Good luck with uriparser! * * * @subsection parsing Parsing URIs (from string to object) * Parsing a URI with uriparser looks like this: * * @code * UriParserStateA state; * UriUriA uri; * * state.uri = &uri; * if (uriParseUriA(&state, "file:///home/user/song.mp3") != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * uriFreeUriMembersA(&uri); * ... * } * ... * uriFreeUriMembersA(&uri); * @endcode * * While the URI object (::UriUriA) holds information about the recogized * parts of the given URI string, the parser state object (::UriParserStateA) * keeps error code and position. This information does not belong to * the URI itself, which is why there are two seperate objects. * * You can reuse parser state objects for parsing several URIs like this: * * @code * UriParserStateA state; * UriUriA uriOne; * UriUriA uriTwo; * * state.uri = &uriOne; * if (uriParseUriA(&state, "file:///home/user/one") != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * uriFreeUriMembersA(&uriOne); * ... * } * ... * state.uri = &uriTwo; * if (uriParseUriA(&state, "file:///home/user/two") != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * uriFreeUriMembersA(&uriOne); * uriFreeUriMembersA(&uriTwo); * ... * } * ... * uriFreeUriMembersA(&uriOne); * uriFreeUriMembersA(&uriTwo); * @endcode * * * @subsection recomposition Recomposing URIs (from object back to string) * According to RFC 3986 * glueing parts of a URI together to form a string is called recomposition. * Before we can recompose a URI object we have to know how much * space the resulting string will take: * * @code * UriUriA uri; * char * uriString; * int charsRequired; * ... * if (uriToStringCharsRequiredA(&uri, &charsRequired) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * charsRequired++; * @endcode * * Now we can tell uriToStringA() to write the string to a given buffer: * * @code * uriString = malloc(charsRequired * sizeof(char)); * if (uriString == NULL) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * if (uriToStringA(uriString, &uri, charsRequired, NULL) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * @endcode * * @remarks * Incrementing charsRequired by 1 is required since * uriToStringCharsRequiredA() returns the length of the string * as strlen() does, but uriToStringA() works with the number * of maximum characters to be written including the * zero-terminator. * * * @subsection resolution Resolving References * Reference Resolution * is the process of turning a (relative) URI reference into an absolute URI by applying a base * URI to it. In code it looks like this: * * @code * UriUriA absoluteDest; * UriUriA relativeSource; * UriUriA absoluteBase; * ... * /COMMENT_HACK* relativeSource holds "../TWO" now *COMMENT_HACK/ * /COMMENT_HACK* absoluteBase holds "file:///one/two/three" now *COMMENT_HACK/ * if (uriAddBaseUriA(&absoluteDest, &relativeSource, &absoluteBase) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * uriFreeUriMembersA(&absoluteDest); * ... * } * /COMMENT_HACK* absoluteDest holds "file:///one/TWO" now *COMMENT_HACK/ * ... * uriFreeUriMembersA(&absoluteDest); * @endcode * * @remarks * uriAddBaseUriA() does not normalize the resulting URI. * Usually you might want to pass it through uriNormalizeSyntaxA() after. * * * @subsection shortening Creating References * Reference Creation is the inverse process of Reference Resolution: A common base URI * is "substracted" from an absolute URI to make a (relative) reference. * If the base URI is not common the remaining URI will still be absolute, i.e. will * carry a scheme * * @code * UriUriA dest; * UriUriA absoluteSource; * UriUriA absoluteBase; * ... * /COMMENT_HACK* absoluteSource holds "file:///one/TWO" now *COMMENT_HACK/ * /COMMENT_HACK* absoluteBase holds "file:///one/two/three" now *COMMENT_HACK/ * if (uriRemoveBaseUriA(&dest, &absoluteSource, &absoluteBase, URI_FALSE) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * uriFreeUriMembersA(&dest); * ... * } * /COMMENT_HACK* dest holds "../TWO" now *COMMENT_HACK/ * ... * uriFreeUriMembersA(&dest); * @endcode * * The fourth parameter is the domain root mode. With URI_FALSE as above this will produce * URIs relative to the base URI. With URI_TRUE the resulting URI will be relative to the * domain root instead, e.g. "/one/TWO" in this case. * * * @subsection filenames Filenames and URIs * Converting filenames to and from URIs works on strings directly, * i.e. without creating an URI object. * * @code * const char * const absFilename = "E:\\Documents and Settings"; * const int bytesNeeded = 8 + 3 * strlen(absFilename) + 1; * char * absUri = malloc(bytesNeeded * sizeof(char)); * if (uriWindowsFilenameToUriStringA(absFilename, absUri) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * free(absUri); * ... * } * /COMMENT_HACK* absUri is "file:///E:/Documents%20and%20Settings" now *COMMENT_HACK/ * ... * free(absUri); * @endcode * * Conversion works .. * - for relative or absolute values, * - in both directions (filenames <--> URIs) and * - with Unix and Windows filenames. * * All you have to do is to choose the right function for the task and allocate * the required space (in characters) for the target buffer. * Let me present you an overview: * * - Filename --> URI * - uriUnixFilenameToUriStringA()\n * Space required: [7 +] 3 * len(filename) + 1 * - uriWindowsFilenameToUriStringA()\n * Space required: [8 +] 3 * len(filename) + 1 * - URI --> filename * - uriUriStringToUnixFilenameA()\n * Space required: len(uriString) + 1 [- 7] * - uriUriStringToWindowsFilenameA()\n * Space required: len(uriString) + 1 [- 8] * * * @subsection normalization Normalizing URIs * Sometimes we come accross unnecessarily long URIs like "http://example.org/one/two/../../one". * The algorithm we can use to shorten this URI down to "http://example.org/one" is called * Syntax-Based Normalization. * Note that normalizing a URI does more than just "stripping dot segments". Please have a look at * Section 6.2.2 of RFC 3986 * for the full description. * * As we asked uriToStringCharsRequiredA() for the required space when converting * a URI object back to a sring, we can ask uriNormalizeSyntaxMaskRequiredA() for * the parts of a URI that require normalization and then pass this normalization * mask to uriNormalizeSyntaxExA(): * * @code * const unsigned int dirtyParts = uriNormalizeSyntaxMaskRequiredA(&uri); * if (uriNormalizeSyntaxExA(&uri, dirtyParts) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * @endcode * * If you don't want to normalize all parts of the URI you can pass a custom * mask as well: * * @code * const unsigned int normMask = URI_NORMALIZE_SCHEME | URI_NORMALIZE_USER_INFO; * if (uriNormalizeSyntaxExA(&uri, normMask) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * @endcode * * Please see ::UriNormalizationMaskEnum for the complete set of flags. * * On the other hand calling plain uriNormalizeSyntaxA() (without the "Ex") * saves you thinking about single parts, as it queries uriNormalizeSyntaxMaskRequiredA() * internally: * * @code * if (uriNormalizeSyntaxA(&uri) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * @endcode * * * @section querystrings Working with query strings * RFC 3986 * itself does not understand the query part of a URI as a list of key/value pairs. * But HTML 2.0 does and defines a media type application/x-www-form-urlencoded * in in section 8.2.1 * of RFC 1866. * uriparser allows you to dissect (or parse) a query string into unescaped key/value pairs * and back. * * To dissect the query part of a just-parsed URI you could write code like this: * * @code * UriUriA uri; * UriQueryListA * queryList; * int itemCount; * ... * if (uriDissectQueryMallocA(&queryList, &itemCount, uri.query.first, * uri.query.afterLast) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * ... * uriFreeQueryListA(queryList); * @endcode * * @remarks * - NULL in the value member means there was no '=' in the item text as with "?abc&def". * - An empty string in the value member means there was '=' in the item as with "?abc=&def". * * * To compose a query string from a query list you could write code like this: * * @code * int charsRequired; * int charsWritten; * char * queryString; * ... * if (uriComposeQueryCharsRequiredA(queryList, &charsRequired) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * queryString = malloc((charsRequired + 1) * sizeof(char)); * if (queryString == NULL) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * if (uriComposeQueryA(queryString, queryList, charsRequired + 1, &charsWritten) != URI_SUCCESS) { * /COMMENT_HACK* Failure *COMMENT_HACK/ * ... * } * ... * free(queryString); * @endcode * * * @section chartypes Ansi and Unicode * uriparser comes with two versions of every structure and function: * one handling Ansi text (char *) and one working with Unicode text (wchar_t *), * for instance * - uriParseUriA() for Ansi and * - uriParseUriW() for Unicode. * * This tutorial only shows the usage of the Ansi editions but * their Unicode counterparts work in the very same way. * * * @section autoconf Autoconf Check * You can use the code below to make ./configure test for presence * of uriparser 0.6.4 or later. * *

Abstract

   A Uniform Resource Identifier (URI) is a compact sequence of
   characters that identifies an abstract or physical resource.  This
   specification defines the generic URI syntax and a process for
   resolving URI references that might be in relative form, along with
   guidelines and security considerations for the use of URIs on the
   Internet.  The URI syntax defines a grammar that is a superset of all
   valid URIs, allowing an implementation to parse the common components
   of a URI reference without knowing the scheme-specific requirements
   of every possible identifier.  This specification does not define a
   generative grammar for URIs; that task is performed by the individual
   specifications of each URI scheme.

RFC 3986                   URI Generic Syntax               January 2005



1.  Introduction


   A Uniform Resource Identifier (URI) provides a simple and extensible
   means for identifying a resource.  This specification of URI syntax
   and semantics is derived from concepts introduced by the World Wide
   Web global information initiative, whose use of these identifiers
   dates from 1990 and is described in "Universal Resource Identifiers
   in WWW" [RFC1630].  The syntax is designed to meet the
   recommendations laid out in "Functional Recommendations for Internet
   Resource Locators" [RFC1736] and "Functional Requirements for Uniform
   Resource Names" [RFC1737].

   This document obsoletes [RFC2396], which merged "Uniform Resource
   Locators" [RFC1738] and "Relative Uniform Resource Locators"
   [RFC1808] in order to define a single, generic syntax for all URIs.
   It obsoletes [RFC2732], which introduced syntax for an IPv6 address.
   It excludes portions of RFC 1738 that defined the specific syntax of
   individual URI schemes; those portions will be updated as separate
   documents.  The process for registration of new URI schemes is
   defined separately by [BCP35].  Advice for designers of new URI
   schemes can be found in [RFC2718].  All significant changes from RFC
   2396 are noted in Appendix D.

   This specification uses the terms "character" and "coded character
   set" in accordance with the definitions provided in [BCP19], and
   "character encoding" in place of what [BCP19] refers to as a
   "charset".


1.1.  Overview of URIs


   URIs are characterized as follows:

   Uniform

      Uniformity provides several benefits.  It allows different types
      of resource identifiers to be used in the same context, even when
      the mechanisms used to access those resources may differ.  It
      allows uniform semantic interpretation of common syntactic
      conventions across different types of resource identifiers.  It
      allows introduction of new types of resource identifiers without
      interfering with the way that existing identifiers are used.  It
      allows the identifiers to be reused in many different contexts,
      thus permitting new applications or protocols to leverage a pre-
      existing, large, and widely used set of resource identifiers.

RFC 3986                   URI Generic Syntax               January 2005


   Resource

      This specification does not limit the scope of what might be a
      resource; rather, the term "resource" is used in a general sense
      for whatever might be identified by a URI.  Familiar examples
      include an electronic document, an image, a source of information
      with a consistent purpose (e.g., "today's weather report for Los
      Angeles"), a service (e.g., an HTTP-to-SMS gateway), and a
      collection of other resources.  A resource is not necessarily
      accessible via the Internet; e.g., human beings, corporations, and
      bound books in a library can also be resources.  Likewise,
      abstract concepts can be resources, such as the operators and
      operands of a mathematical equation, the types of a relationship
      (e.g., "parent" or "employee"), or numeric values (e.g., zero,
      one, and infinity).

   Identifier

      An identifier embodies the information required to distinguish
      what is being identified from all other things within its scope of
      identification.  Our use of the terms "identify" and "identifying"
      refer to this purpose of distinguishing one resource from all
      other resources, regardless of how that purpose is accomplished
      (e.g., by name, address, or context).  These terms should not be
      mistaken as an assumption that an identifier defines or embodies
      the identity of what is referenced, though that may be the case
      for some identifiers.  Nor should it be assumed that a system
      using URIs will access the resource identified: in many cases,
      URIs are used to denote resources without any intention that they
      be accessed.  Likewise, the "one" resource identified might not be
      singular in nature (e.g., a resource might be a named set or a
      mapping that varies over time).

   A URI is an identifier consisting of a sequence of characters
   matching the syntax rule named <URI> in Section 3.  It enables
   uniform identification of resources via a separately defined
   extensible set of naming schemes (Section 3.1).  How that
   identification is accomplished, assigned, or enabled is delegated to
   each scheme specification.

   This specification does not place any limits on the nature of a
   resource, the reasons why an application might seek to refer to a
   resource, or the kinds of systems that might use URIs for the sake of
   identifying resources.  This specification does not require that a
   URI persists in identifying the same resource over time, though that
   is a common goal of all URI schemes.  Nevertheless, nothing in this





Berners-Lee, et al.         Standards Track                     [Page 5]
 
RFC 3986                   URI Generic Syntax               January 2005


   specification prevents an application from limiting itself to
   particular types of resources, or to a subset of URIs that maintains
   characteristics desired by that application.

   URIs have a global scope and are interpreted consistently regardless
   of context, though the result of that interpretation may be in
   relation to the end-user's context.  For example, "http://localhost/"
   has the same interpretation for every user of that reference, even
   though the network interface corresponding to "localhost" may be
   different for each end-user: interpretation is independent of access.
   However, an action made on the basis of that reference will take
   place in relation to the end-user's context, which implies that an
   action intended to refer to a globally unique thing must use a URI
   that distinguishes that resource from all other things.  URIs that
   identify in relation to the end-user's local context should only be
   used when the context itself is a defining aspect of the resource,
   such as when an on-line help manual refers to a file on the end-
   user's file system (e.g., "file:///etc/hosts").


1.1.1.  Generic Syntax


   Each URI begins with a scheme name, as defined in Section 3.1, that
   refers to a specification for assigning identifiers within that
   scheme.  As such, the URI syntax is a federated and extensible naming
   system wherein each scheme's specification may further restrict the
   syntax and semantics of identifiers using that scheme.

   This specification defines those elements of the URI syntax that are
   required of all URI schemes or are common to many URI schemes.  It
   thus defines the syntax and semantics needed to implement a scheme-
   independent parsing mechanism for URI references, by which the
   scheme-dependent handling of a URI can be postponed until the
   scheme-dependent semantics are needed.  Likewise, protocols and data
   formats that make use of URI references can refer to this
   specification as a definition for the range of syntax allowed for all
   URIs, including those schemes that have yet to be defined.  This
   decouples the evolution of identification schemes from the evolution
   of protocols, data formats, and implementations that make use of
   URIs.

   A parser of the generic URI syntax can parse any URI reference into
   its major components.  Once the scheme is determined, further
   scheme-specific parsing can be performed on the components.  In other
   words, the URI generic syntax is a superset of the syntax of all URI
   schemes.

1.1.2.  Examples


   The following example URIs illustrate several URI schemes and
   variations in their common syntax components:

      telnet://192.0.2.16:80/

      urn:oasis:names:specification:docbook:dtd:xml:4.1.2



1.1.3.  URI, URL, and URN


   A URI can be further classified as a locator, a name, or both.  The
   term "Uniform Resource Locator" (URL) refers to the subset of URIs
   that, in addition to identifying a resource, provide a means of
   locating the resource by describing its primary access mechanism
   (e.g., its network "location").  The term "Uniform Resource Name"
   (URN) has been used historically to refer to both URIs under the
   "urn" scheme [RFC2141], which are required to remain globally unique
   and persistent even when the resource ceases to exist or becomes
   unavailable, and to any other URI with the properties of a name.

   An individual scheme does not have to be classified as being just one
   of "name" or "locator".  Instances of URIs from any given scheme may
   have the characteristics of names or locators or both, often
   depending on the persistence and care in the assignment of
   identifiers by the naming authority, rather than on any quality of
   the scheme.  Future specifications and related documentation should
   use the general term "URI" rather than the more restrictive terms
   "URL" and "URN" [RFC3305].

1.2.  Design Considerations



1.2.1.  Transcription


   The URI syntax has been designed with global transcription as one of
   its main considerations.  A URI is a sequence of characters from a
   very limited set: the letters of the basic Latin alphabet, digits,
   and a few special characters.  A URI may be represented in a variety
   of ways; e.g., ink on paper, pixels on a screen, or a sequence of
   character encoding octets.  The interpretation of a URI depends only
   on the characters used and not on how those characters are
   represented in a network protocol.

   The goal of transcription can be described by a simple scenario.
   Imagine two colleagues, Sam and Kim, sitting in a pub at an
   international conference and exchanging research ideas.  Sam asks Kim
   for a location to get more information, so Kim writes the URI for the
   research site on a napkin.  Upon returning home, Sam takes out the
   napkin and types the URI into a computer, which then retrieves the
   information to which Kim referred.

   There are several design considerations revealed by the scenario:

   o  A URI is a sequence of characters that is not always represented
      as a sequence of octets.

   o  A URI might be transcribed from a non-network source and thus
      should consist of characters that are most likely able to be
      entered into a computer, within the constraints imposed by
      keyboards (and related input devices) across languages and
      locales.

   o  A URI often has to be remembered by people, and it is easier for
      people to remember a URI when it consists of meaningful or
      familiar components.

   These design considerations are not always in alignment.  For
   example, it is often the case that the most meaningful name for a URI
   component would require characters that cannot be typed into some
   systems.  The ability to transcribe a resource identifier from one
   medium to another has been considered more important than having a
   URI consist of the most meaningful of components.

   In local or regional contexts and with improving technology, users
   might benefit from being able to use a wider range of characters;
   such use is not defined by this specification.  Percent-encoded
   octets (Section 2.1) may be used within a URI to represent characters
   outside the range of the US-ASCII coded character set if this



Berners-Lee, et al.         Standards Track                     [Page 8]
 
RFC 3986                   URI Generic Syntax               January 2005


   representation is allowed by the scheme or by the protocol element in
   which the URI is referenced.  Such a definition should specify the
   character encoding used to map those characters to octets prior to
   being percent-encoded for the URI.


1.2.2.  Separating Identification from Interaction


   A common misunderstanding of URIs is that they are only used to refer
   to accessible resources.  The URI itself only provides
   identification; access to the resource is neither guaranteed nor
   implied by the presence of a URI.  Instead, any operation associated
   with a URI reference is defined by the protocol element, data format
   attribute, or natural language text in which it appears.

   Given a URI, a system may attempt to perform a variety of operations
   on the resource, as might be characterized by words such as "access",
   "update", "replace", or "find attributes".  Such operations are
   defined by the protocols that make use of URIs, not by this
   specification.  However, we do use a few general terms for describing
   common operations on URIs.  URI "resolution" is the process of
   determining an access mechanism and the appropriate parameters
   necessary to dereference a URI; this resolution may require several
   iterations.  To use that access mechanism to perform an action on the
   URI's resource is to "dereference" the URI.

   When URIs are used within information retrieval systems to identify
   sources of information, the most common form of URI dereference is
   "retrieval": making use of a URI in order to retrieve a
   representation of its associated resource.  A "representation" is a
   sequence of octets, along with representation metadata describing
   those octets, that constitutes a record of the state of the resource
   at the time when the representation is generated.  Retrieval is
   achieved by a process that might include using the URI as a cache key
   to check for a locally cached representation, resolution of the URI
   to determine an appropriate access mechanism (if any), and
   dereference of the URI for the sake of applying a retrieval
   operation.  Depending on the protocols used to perform the retrieval,
   additional information might be supplied about the resource (resource
   metadata) and its relation to other resources.

   URI references in information retrieval systems are designed to be
   late-binding: the result of an access is generally determined when it
   is accessed and may vary over time or due to other aspects of the
   interaction.  These references are created in order to be used in the
   future: what is being identified is not some specific result that was
   obtained in the past, but rather some characteristic that is expected
   to be true for future results.  In such cases, the resource referred
   to by the URI is actually a sameness of characteristics as observed



Berners-Lee, et al.         Standards Track                     [Page 9]
 
RFC 3986                   URI Generic Syntax               January 2005


   over time, perhaps elucidated by additional comments or assertions
   made by the resource provider.

   Although many URI schemes are named after protocols, this does not
   imply that use of these URIs will result in access to the resource
   via the named protocol.  URIs are often used simply for the sake of
   identification.  Even when a URI is used to retrieve a representation
   of a resource, that access might be through gateways, proxies,
   caches, and name resolution services that are independent of the
   protocol associated with the scheme name.  The resolution of some
   URIs may require the use of more than one protocol (e.g., both DNS
   and HTTP are typically used to access an "http" URI's origin server
   when a representation isn't found in a local cache).


1.2.3.  Hierarchical Identifiers


   The URI syntax is organized hierarchically, with components listed in
   order of decreasing significance from left to right.  For some URI
   schemes, the visible hierarchy is limited to the scheme itself:
   everything after the scheme component delimiter (":") is considered
   opaque to URI processing.  Other URI schemes make the hierarchy
   explicit and visible to generic parsing algorithms.

   The generic syntax uses the slash ("/"), question mark ("?"), and
   number sign ("#") characters to delimit components that are
   significant to the generic parser's hierarchical interpretation of an
   identifier.  In addition to aiding the readability of such
   identifiers through the consistent use of familiar syntax, this
   uniform representation of hierarchy across naming schemes allows
   scheme-independent references to be made relative to that hierarchy.

   It is often the case that a group or "tree" of documents has been
   constructed to serve a common purpose, wherein the vast majority of
   URI references in these documents point to resources within the tree
   rather than outside it.  Similarly, documents located at a particular
   site are much more likely to refer to other resources at that site
   than to resources at remote sites.  Relative referencing of URIs
   allows document trees to be partially independent of their location
   and access scheme.  For instance, it is possible for a single set of
   hypertext documents to be simultaneously accessible and traversable
   via each of the "file", "http", and "ftp" schemes if the documents
   refer to each other with relative references.  Furthermore, such
   document trees can be moved, as a whole, without changing any of the
   relative references.

   A relative reference (Section 4.2) refers to a resource by describing
   the difference within a hierarchical name space between the reference
   context and the target URI.  The reference resolution algorithm,



Berners-Lee, et al.         Standards Track                    [Page 10]
 
RFC 3986                   URI Generic Syntax               January 2005


   presented in Section 5, defines how such a reference is transformed
   to the target URI.  As relative references can only be used within
   the context of a hierarchical URI, designers of new URI schemes
   should use a syntax consistent with the generic syntax's hierarchical
   components unless there are compelling reasons to forbid relative
   referencing within that scheme.

      NOTE: Previous specifications used the terms "partial URI" and
      "relative URI" to denote a relative reference to a URI.  As some
      readers misunderstood those terms to mean that relative URIs are a
      subset of URIs rather than a method of referencing URIs, this
      specification simply refers to them as relative references.

   All URI references are parsed by generic syntax parsers when used.
   However, because hierarchical processing has no effect on an absolute
   URI used in a reference unless it contains one or more dot-segments
   (complete path segments of "." or "..", as described in Section 3.3),
   URI scheme specifications can define opaque identifiers by
   disallowing use of slash characters, question mark characters, and
   the URIs "scheme:." and "scheme:..".


1.3.  Syntax Notation


   This specification uses the Augmented Backus-Naur Form (ABNF)
   notation of [RFC2234], including the following core ABNF syntax rules
   defined by that specification: ALPHA (letters), CR (carriage return),
   DIGIT (decimal digits), DQUOTE (double quote), HEXDIG (hexadecimal
   digits), LF (line feed), and SP (space).  The complete URI syntax is
   collected in Appendix A.


2.  Characters


   The URI syntax provides a method of encoding data, presumably for the
   sake of identifying a resource, as a sequence of characters.  The URI
   characters are, in turn, frequently encoded as octets for transport
   or presentation.  This specification does not mandate any particular
   character encoding for mapping between URI characters and the octets
   used to store or transmit those characters.  When a URI appears in a
   protocol element, the character encoding is defined by that protocol;
   without such a definition, a URI is assumed to be in the same
   character encoding as the surrounding text.

   The ABNF notation defines its terminal values to be non-negative
   integers (codepoints) based on the US-ASCII coded character set
   [ASCII].  Because a URI is a sequence of characters, we must invert
   that relation in order to understand the URI syntax.  Therefore, the





Berners-Lee, et al.         Standards Track                    [Page 11]
 
RFC 3986                   URI Generic Syntax               January 2005


   integer values used by the ABNF must be mapped back to their
   corresponding characters via US-ASCII in order to complete the syntax
   rules.

   A URI is composed from a limited set of characters consisting of
   digits, letters, and a few graphic symbols.  A reserved subset of
   those characters may be used to delimit syntax components within a
   URI while the remaining characters, including both the unreserved set
   and those reserved characters not acting as delimiters, define each
   component's identifying data.


2.1.  Percent-Encoding


   A percent-encoding mechanism is used to represent a data octet in a
   component when that octet's corresponding character is outside the
   allowed set or is being used as a delimiter of, or within, the
   component.  A percent-encoded octet is encoded as a character
   triplet, consisting of the percent character "%" followed by the two
   hexadecimal digits representing that octet's numeric value.  For
   example, "%20" is the percent-encoding for the binary octet
   "00100000" (ABNF: %x20), which in US-ASCII corresponds to the space
   character (SP).  Section 2.4 describes when percent-encoding and
   decoding is applied.

      pct-encoded = "%" HEXDIG HEXDIG

   The uppercase hexadecimal digits 'A' through 'F' are equivalent to
   the lowercase digits 'a' through 'f', respectively.  If two URIs
   differ only in the case of hexadecimal digits used in percent-encoded
   octets, they are equivalent.  For consistency, URI producers and
   normalizers should use uppercase hexadecimal digits for all percent-
   encodings.


2.2.  Reserved Characters


   URIs include components and subcomponents that are delimited by
   characters in the "reserved" set.  These characters are called
   "reserved" because they may (or may not) be defined as delimiters by
   the generic syntax, by each scheme-specific syntax, or by the
   implementation-specific syntax of a URI's dereferencing algorithm.
   If data for a URI component would conflict with a reserved
   character's purpose as a delimiter, then the conflicting data must be
   percent-encoded before the URI is formed.








Berners-Lee, et al.         Standards Track                    [Page 12]
 
RFC 3986                   URI Generic Syntax               January 2005


      reserved    = gen-delims / sub-delims

      gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"

      sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

   The purpose of reserved characters is to provide a set of delimiting
   characters that are distinguishable from other data within a URI.
   URIs that differ in the replacement of a reserved character with its
   corresponding percent-encoded octet are not equivalent.  Percent-
   encoding a reserved character, or decoding a percent-encoded octet
   that corresponds to a reserved character, will change how the URI is
   interpreted by most applications.  Thus, characters in the reserved
   set are protected from normalization and are therefore safe to be
   used by scheme-specific and producer-specific algorithms for
   delimiting data subcomponents within a URI.

   A subset of the reserved characters (gen-delims) is used as
   delimiters of the generic URI components described in Section 3.  A
   component's ABNF syntax rule will not use the reserved or gen-delims
   rule names directly; instead, each syntax rule lists the characters
   allowed within that component (i.e., not delimiting it), and any of
   those characters that are also in the reserved set are "reserved" for
   use as subcomponent delimiters within the component.  Only the most
   common subcomponents are defined by this specification; other
   subcomponents may be defined by a URI scheme's specification, or by
   the implementation-specific syntax of a URI's dereferencing
   algorithm, provided that such subcomponents are delimited by
   characters in the reserved set allowed within that component.

   URI producing applications should percent-encode data octets that
   correspond to characters in the reserved set unless these characters
   are specifically allowed by the URI scheme to represent data in that
   component.  If a reserved character is found in a URI component and
   no delimiting role is known for that character, then it must be
   interpreted as representing the data octet corresponding to that
   character's encoding in US-ASCII.


2.3.  Unreserved Characters


   Characters that are allowed in a URI but do not have a reserved
   purpose are called unreserved.  These include uppercase and lowercase
   letters, decimal digits, hyphen, period, underscore, and tilde.

      unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"





Berners-Lee, et al.         Standards Track                    [Page 13]
 
RFC 3986                   URI Generic Syntax               January 2005


   URIs that differ in the replacement of an unreserved character with
   its corresponding percent-encoded US-ASCII octet are equivalent: they
   identify the same resource.  However, URI comparison implementations
   do not always perform normalization prior to comparison (see Section
   6).  For consistency, percent-encoded octets in the ranges of ALPHA
   (%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
   underscore (%5F), or tilde (%7E) should not be created by URI
   producers and, when found in a URI, should be decoded to their
   corresponding unreserved characters by URI normalizers.


2.4.  When to Encode or Decode


   Under normal circumstances, the only time when octets within a URI
   are percent-encoded is during the process of producing the URI from
   its component parts.  This is when an implementation determines which
   of the reserved characters are to be used as subcomponent delimiters
   and which can be safely used as data.  Once produced, a URI is always
   in its percent-encoded form.

   When a URI is dereferenced, the components and subcomponents
   significant to the scheme-specific dereferencing process (if any)
   must be parsed and separated before the percent-encoded octets within
   those components can be safely decoded, as otherwise the data may be
   mistaken for component delimiters.  The only exception is for
   percent-encoded octets corresponding to characters in the unreserved
   set, which can be decoded at any time.  For example, the octet
   corresponding to the tilde ("~") character is often encoded as "%7E"
   by older URI processing implementations; the "%7E" can be replaced by
   "~" without changing its interpretation.

   Because the percent ("%") character serves as the indicator for
   percent-encoded octets, it must be percent-encoded as "%25" for that
   octet to be used as data within a URI.  Implementations must not
   percent-encode or decode the same string more than once, as decoding
   an already decoded string might lead to misinterpreting a percent
   data octet as the beginning of a percent-encoding, or vice versa in
   the case of percent-encoding an already percent-encoded string.


2.5.  Identifying Data


   URI characters provide identifying data for each of the URI
   components, serving as an external interface for identification
   between systems.  Although the presence and nature of the URI
   production interface is hidden from clients that use its URIs (and is
   thus beyond the scope of the interoperability requirements defined by
   this specification), it is a frequent source of confusion and errors
   in the interpretation of URI character issues.  Implementers have to
   be aware that there are multiple character encodings involved in the



Berners-Lee, et al.         Standards Track                    [Page 14]
 
RFC 3986                   URI Generic Syntax               January 2005


   production and transmission of URIs: local name and data encoding,
   public interface encoding, URI character encoding, data format
   encoding, and protocol encoding.

   Local names, such as file system names, are stored with a local
   character encoding.  URI producing applications (e.g., origin
   servers) will typically use the local encoding as the basis for
   producing meaningful names.  The URI producer will transform the
   local encoding to one that is suitable for a public interface and
   then transform the public interface encoding into the restricted set
   of URI characters (reserved, unreserved, and percent-encodings).
   Those characters are, in turn, encoded as octets to be used as a
   reference within a data format (e.g., a document charset), and such
   data formats are often subsequently encoded for transmission over
   Internet protocols.

   For most systems, an unreserved character appearing within a URI
   component is interpreted as representing the data octet corresponding
   to that character's encoding in US-ASCII.  Consumers of URIs assume
   that the letter "X" corresponds to the octet "01011000", and even
   when that assumption is incorrect, there is no harm in making it.  A
   system that internally provides identifiers in the form of a
   different character encoding, such as EBCDIC, will generally perform
   character translation of textual identifiers to UTF-8 [STD63] (or
   some other superset of the US-ASCII character encoding) at an
   internal interface, thereby providing more meaningful identifiers
   than those resulting from simply percent-encoding the original
   octets.

   For example, consider an information service that provides data,
   stored locally using an EBCDIC-based file system, to clients on the
   Internet through an HTTP server.  When an author creates a file with
   the name "Laguna Beach" on that file system, the "http" URI
   corresponding to that resource is expected to contain the meaningful
   string "Laguna%20Beach".  If, however, that server produces URIs by
   using an overly simplistic raw octet mapping, then the result would
   be a URI containing "%D3%81%87%A4%95%81@%C2%85%81%83%88".  An
   internal transcoding interface fixes this problem by transcoding the
   local name to a superset of US-ASCII prior to producing the URI.
   Naturally, proper interpretation of an incoming URI on such an
   interface requires that percent-encoded octets be decoded (e.g.,
   "%20" to SP) before the reverse transcoding is applied to obtain the
   local name.

   In some cases, the internal interface between a URI component and the
   identifying data that it has been crafted to represent is much less
   direct than a character encoding translation.  For example, portions
   of a URI might reflect a query on non-ASCII data, or numeric



Berners-Lee, et al.         Standards Track                    [Page 15]
 
RFC 3986                   URI Generic Syntax               January 2005


   coordinates on a map.  Likewise, a URI scheme may define components
   with additional encoding requirements that are applied prior to
   forming the component and producing the URI.

   When a new URI scheme defines a component that represents textual
   data consisting of characters from the Universal Character Set [UCS],
   the data should first be encoded as octets according to the UTF-8
   character encoding [STD63]; then only those octets that do not
   correspond to characters in the unreserved set should be percent-
   encoded.  For example, the character A would be represented as "A",
   the character LATIN CAPITAL LETTER A WITH GRAVE would be represented
   as "%C3%80", and the character KATAKANA LETTER A would be represented
   as "%E3%82%A2".


3.  Syntax Components


   The generic URI syntax consists of a hierarchical sequence of
   components referred to as the scheme, authority, path, query, and
   fragment.

      URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

      hier-part   = "//" authority path-abempty
                  / path-absolute
                  / path-rootless
                  / path-empty

   The scheme and path components are required, though the path may be
   empty (no characters).  When authority is present, the path must
   either be empty or begin with a slash ("/") character.  When
   authority is not present, the path cannot begin with two slash
   characters ("//").  These restrictions result in five different ABNF
   rules for a path (Section 3.3), only one of which will match any
   given URI reference.

   The following are two example URIs and their component parts:

         foo://example.com:8042/over/there?name=ferret#nose
         \_/   \______________/\_________/ \_________/ \__/
          |           |            |            |        |
       scheme     authority       path        query   fragment
          |   _____________________|__
         / \ /                        \
         urn:example:animal:ferret:nose

RFC 3986                   URI Generic Syntax               January 2005



3.1.  Scheme


   Each URI begins with a scheme name that refers to a specification for
   assigning identifiers within that scheme.  As such, the URI syntax is
   a federated and extensible naming system wherein each scheme's
   specification may further restrict the syntax and semantics of
   identifiers using that scheme.

   Scheme names consist of a sequence of characters beginning with a
   letter and followed by any combination of letters, digits, plus
   ("+"), period ("."), or hyphen ("-").  Although schemes are case-
   insensitive, the canonical form is lowercase and documents that
   specify schemes must do so with lowercase letters.  An implementation
   should accept uppercase letters as equivalent to lowercase in scheme
   names (e.g., allow "HTTP" as well as "http") for the sake of
   robustness but should only produce lowercase scheme names for
   consistency.

      scheme      = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )

   Individual schemes are not specified by this document.  The process
   for registration of new URI schemes is defined separately by [BCP35].
   The scheme registry maintains the mapping between scheme names and
   their specifications.  Advice for designers of new URI schemes can be
   found in [RFC2718].  URI scheme specifications must define their own
   syntax so that all strings matching their scheme-specific syntax will
   also match the <absolute-URI> grammar, as described in Section 4.3.

   When presented with a URI that violates one or more scheme-specific
   restrictions, the scheme-specific resolution process should flag the
   reference as an error rather than ignore the unused parts; doing so
   reduces the number of equivalent URIs and helps detect abuses of the
   generic syntax, which might indicate that the URI has been
   constructed to mislead the user (Section 7.6).


3.2.  Authority


   Many URI schemes include a hierarchical element for a naming
   authority so that governance of the name space defined by the
   remainder of the URI is delegated to that authority (which may, in
   turn, delegate it further).  The generic syntax provides a common
   means for distinguishing an authority based on a registered name or
   server address, along with optional port and user information.

   The authority component is preceded by a double slash ("//") and is
   terminated by the next slash ("/"), question mark ("?"), or number
   sign ("#") character, or by the end of the URI.




Berners-Lee, et al.         Standards Track                    [Page 17]
 
RFC 3986                   URI Generic Syntax               January 2005


      authority   = [ userinfo "@" ] host [ ":" port ]

   URI producers and normalizers should omit the ":" delimiter that
   separates host from port if the port component is empty.  Some
   schemes do not allow the userinfo and/or port subcomponents.

   If a URI contains an authority component, then the path component
   must either be empty or begin with a slash ("/") character.  Non-
   validating parsers (those that merely separate a URI reference into
   its major components) will often ignore the subcomponent structure of
   authority, treating it as an opaque string from the double-slash to
   the first terminating delimiter, until such time as the URI is
   dereferenced.


3.2.1.  User Information


   The userinfo subcomponent may consist of a user name and, optionally,
   scheme-specific information about how to gain authorization to access
   the resource.  The user information, if present, is followed by a
   commercial at-sign ("@") that delimits it from the host.

      userinfo    = *( unreserved / pct-encoded / sub-delims / ":" )

   Use of the format "user:password" in the userinfo field is
   deprecated.  Applications should not render as clear text any data
   after the first colon (":") character found within a userinfo
   subcomponent unless the data after the colon is the empty string
   (indicating no password).  Applications may choose to ignore or
   reject such data when it is received as part of a reference and
   should reject the storage of such data in unencrypted form.  The
   passing of authentication information in clear text has proven to be
   a security risk in almost every case where it has been used.

   Applications that render a URI for the sake of user feedback, such as
   in graphical hypertext browsing, should render userinfo in a way that
   is distinguished from the rest of a URI, when feasible.  Such
   rendering will assist the user in cases where the userinfo has been
   misleadingly crafted to look like a trusted domain name
   (Section 7.6).


3.2.2.  Host


   The host subcomponent of authority is identified by an IP literal
   encapsulated within square brackets, an IPv4 address in dotted-
   decimal form, or a registered name.  The host subcomponent is case-
   insensitive.  The presence of a host subcomponent within a URI does
   not imply that the scheme requires access to the given host on the
   Internet.  In many cases, the host syntax is used only for the sake



Berners-Lee, et al.         Standards Track                    [Page 18]
 
RFC 3986                   URI Generic Syntax               January 2005


   of reusing the existing registration process created and deployed for
   DNS, thus obtaining a globally unique name without the cost of
   deploying another registry.  However, such use comes with its own
   costs: domain name ownership may change over time for reasons not
   anticipated by the URI producer.  In other cases, the data within the
   host component identifies a registered name that has nothing to do
   with an Internet host.  We use the name "host" for the ABNF rule
   because that is its most common purpose, not its only purpose.

      host        = IP-literal / IPv4address / reg-name

   The syntax rule for host is ambiguous because it does not completely
   distinguish between an IPv4address and a reg-name.  In order to
   disambiguate the syntax, we apply the "first-match-wins" algorithm:
   If host matches the rule for IPv4address, then it should be
   considered an IPv4 address literal and not a reg-name.  Although host
   is case-insensitive, producers and normalizers should use lowercase
   for registered names and hexadecimal addresses for the sake of
   uniformity, while only using uppercase letters for percent-encodings.

   A host identified by an Internet Protocol literal address, version 6
   [RFC3513] or later, is distinguished by enclosing the IP literal
   within square brackets ("[" and "]").  This is the only place where
   square bracket characters are allowed in the URI syntax.  In
   anticipation of future, as-yet-undefined IP literal address formats,
   an implementation may use an optional version flag to indicate such a
   format explicitly rather than rely on heuristic determination.

      IP-literal = "[" ( IPv6address / IPvFuture  ) "]"

      IPvFuture  = "v" 1*HEXDIG "." 1*( unreserved / sub-delims / ":" )

   The version flag does not indicate the IP version; rather, it
   indicates future versions of the literal format.  As such,
   implementations must not provide the version flag for the existing
   IPv4 and IPv6 literal address forms described below.  If a URI
   containing an IP-literal that starts with "v" (case-insensitive),
   indicating that the version flag is present, is dereferenced by an
   application that does not know the meaning of that version flag, then
   the application should return an appropriate error for "address
   mechanism not supported".

   A host identified by an IPv6 literal address is represented inside
   the square brackets without a preceding version flag.  The ABNF
   provided here is a translation of the text definition of an IPv6
   literal address provided in [RFC3513].  This syntax does not support
   IPv6 scoped addressing zone identifiers.




Berners-Lee, et al.         Standards Track                    [Page 19]
 
RFC 3986                   URI Generic Syntax               January 2005


   A 128-bit IPv6 address is divided into eight 16-bit pieces.  Each
   piece is represented numerically in case-insensitive hexadecimal,
   using one to four hexadecimal digits (leading zeroes are permitted).
   The eight encoded pieces are given most-significant first, separated
   by colon characters.  Optionally, the least-significant two pieces
   may instead be represented in IPv4 address textual format.  A
   sequence of one or more consecutive zero-valued 16-bit pieces within
   the address may be elided, omitting all their digits and leaving
   exactly two consecutive colons in their place to mark the elision.

      IPv6address =                            6( h16 ":" ) ls32
                  /                       "::" 5( h16 ":" ) ls32
                  / [               h16 ] "::" 4( h16 ":" ) ls32
                  / [ *1( h16 ":" ) h16 ] "::" 3( h16 ":" ) ls32
                  / [ *2( h16 ":" ) h16 ] "::" 2( h16 ":" ) ls32
                  / [ *3( h16 ":" ) h16 ] "::"    h16 ":"   ls32
                  / [ *4( h16 ":" ) h16 ] "::"              ls32
                  / [ *5( h16 ":" ) h16 ] "::"              h16
                  / [ *6( h16 ":" ) h16 ] "::"

      ls32        = ( h16 ":" h16 ) / IPv4address
                  ; least-significant 32 bits of address

      h16         = 1*4HEXDIG
                  ; 16 bits of address represented in hexadecimal

   A host identified by an IPv4 literal address is represented in
   dotted-decimal notation (a sequence of four decimal numbers in the
   range 0 to 255, separated by "."), as described in [RFC1123] by
   reference to [RFC0952].  Note that other forms of dotted notation may
   be interpreted on some platforms, as described in Section 7.4, but
   only the dotted-decimal form of four octets is allowed by this
   grammar.

      IPv4address = dec-octet "." dec-octet "." dec-octet "." dec-octet

      dec-octet   = DIGIT                 ; 0-9
                  / %x31-39 DIGIT         ; 10-99
                  / "1" 2DIGIT            ; 100-199
                  / "2" %x30-34 DIGIT     ; 200-249
                  / "25" %x30-35          ; 250-255

   A host identified by a registered name is a sequence of characters
   usually intended for lookup within a locally defined host or service
   name registry, though the URI's scheme-specific semantics may require
   that a specific registry (or fixed name table) be used instead.  The
   most common name registry mechanism is the Domain Name System (DNS).
   A registered name intended for lookup in the DNS uses the syntax



Berners-Lee, et al.         Standards Track                    [Page 20]
 
RFC 3986                   URI Generic Syntax               January 2005


   defined in Section 3.5 of [RFC1034] and Section 2.1 of [RFC1123].
   Such a name consists of a sequence of domain labels separated by ".",
   each domain label starting and ending with an alphanumeric character
   and possibly also containing "-" characters.  The rightmost domain
   label of a fully qualified domain name in DNS may be followed by a
   single "." and should be if it is necessary to distinguish between
   the complete domain name and some local domain.

      reg-name    = *( unreserved / pct-encoded / sub-delims )

   If the URI scheme defines a default for host, then that default
   applies when the host subcomponent is undefined or when the
   registered name is empty (zero length).  For example, the "file" URI
   scheme is defined so that no authority, an empty host, and
   "localhost" all mean the end-user's machine, whereas the "http"
   scheme considers a missing authority or empty host invalid.

   This specification does not mandate a particular registered name
   lookup technology and therefore does not restrict the syntax of reg-
   name beyond what is necessary for interoperability.  Instead, it
   delegates the issue of registered name syntax conformance to the
   operating system of each application performing URI resolution, and
   that operating system decides what it will allow for the purpose of
   host identification.  A URI resolution implementation might use DNS,
   host tables, yellow pages, NetInfo, WINS, or any other system for
   lookup of registered names.  However, a globally scoped naming
   system, such as DNS fully qualified domain names, is necessary for
   URIs intended to have global scope.  URI producers should use names
   that conform to the DNS syntax, even when use of DNS is not
   immediately apparent, and should limit these names to no more than
   255 characters in length.

   The reg-name syntax allows percent-encoded octets in order to
   represent non-ASCII registered names in a uniform way that is
   independent of the underlying name resolution technology.  Non-ASCII
   characters must first be encoded according to UTF-8 [STD63], and then
   each octet of the corresponding UTF-8 sequence must be percent-
   encoded to be represented as URI characters.  URI producing
   applications must not use percent-encoding in host unless it is used
   to represent a UTF-8 character sequence.  When a non-ASCII registered
   name represents an internationalized domain name intended for
   resolution via the DNS, the name must be transformed to the IDNA
   encoding [RFC3490] prior to name lookup.  URI producers should
   provide these registered names in the IDNA encoding, rather than a
   percent-encoding, if they wish to maximize interoperability with
   legacy URI resolvers.

3.2.3.  Port


   The port subcomponent of authority is designated by an optional port
   number in decimal following the host and delimited from it by a
   single colon (":") character.

      port        = *DIGIT

   A scheme may define a default port.  For example, the "http" scheme
   defines a default port of "80", corresponding to its reserved TCP
   port number.  The type of port designated by the port number (e.g.,
   TCP, UDP, SCTP) is defined by the URI scheme.  URI producers and
   normalizers should omit the port component and its ":" delimiter if
   port is empty or if its value would be the same as that of the
   scheme's default.


3.3.  Path


   The path component contains data, usually organized in hierarchical
   form, that, along with data in the non-hierarchical query component
   (Section 3.4), serves to identify a resource within the scope of the
   URI's scheme and naming authority (if any).  The path is terminated
   by the first question mark ("?") or number sign ("#") character, or
   by the end of the URI.

   If a URI contains an authority component, then the path component
   must either be empty or begin with a slash ("/") character.  If a URI
   does not contain an authority component, then the path cannot begin
   with two slash characters ("//").  In addition, a URI reference
   (Section 4.1) may be a relative-path reference, in which case the
   first path segment cannot contain a colon (":") character.  The ABNF
   requires five separate rules to disambiguate these cases, only one of
   which will match the path substring within a given URI reference.  We
   use the generic term "path component" to describe the URI substring
   matched by the parser to one of these rules.

      path          = path-abempty    ; begins with "/" or is empty
                    / path-absolute   ; begins with "/" but not "//"
                    / path-noscheme   ; begins with a non-colon segment
                    / path-rootless   ; begins with a segment
                    / path-empty      ; zero characters

      path-abempty  = *( "/" segment )
      path-absolute = "/" [ segment-nz *( "/" segment ) ]
      path-noscheme = segment-nz-nc *( "/" segment )
      path-rootless = segment-nz *( "/" segment )
      path-empty    = 0<pchar>




Berners-Lee, et al.         Standards Track                    [Page 22]
 
RFC 3986                   URI Generic Syntax               January 2005


      segment       = *pchar
      segment-nz    = 1*pchar
      segment-nz-nc = 1*( unreserved / pct-encoded / sub-delims / "@" )
                    ; non-zero-length segment without any colon ":"

      pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"

   A path consists of a sequence of path segments separated by a slash
   ("/") character.  A path is always defined for a URI, though the
   defined path may be empty (zero length).  Use of the slash character
   to indicate hierarchy is only required when a URI will be used as the
   context for relative references.  For example, the URI
   <mailto:fred@example.com> has a path of "fred@example.com", whereas
   the URI <foo://info.example.com?fred> has an empty path.

   The path segments "." and "..", also known as dot-segments, are
   defined for relative reference within the path name hierarchy.  They
   are intended for use at the beginning of a relative-path reference
   (Section 4.2) to indicate relative position within the hierarchical
   tree of names.  This is similar to their role within some operating
   systems' file directory structures to indicate the current directory
   and parent directory, respectively.  However, unlike in a file
   system, these dot-segments are only interpreted within the URI path
   hierarchy and are removed as part of the resolution process (Section
   5.2).

   Aside from dot-segments in hierarchical paths, a path segment is
   considered opaque by the generic syntax.  URI producing applications
   often use the reserved characters allowed in a segment to delimit
   scheme-specific or dereference-handler-specific subcomponents.  For
   example, the semicolon (";") and equals ("=") reserved characters are
   often used to delimit parameters and parameter values applicable to
   that segment.  The comma (",") reserved character is often used for
   similar purposes.  For example, one URI producer might use a segment
   such as "name;v=1.1" to indicate a reference to version 1.1 of
   "name", whereas another might use a segment such as "name,1.1" to
   indicate the same.  Parameter types may be defined by scheme-specific
   semantics, but in most cases the syntax of a parameter is specific to
   the implementation of the URI's dereferencing algorithm.


3.4.  Query


   The query component contains non-hierarchical data that, along with
   data in the path component (Section 3.3), serves to identify a
   resource within the scope of the URI's scheme and naming authority
   (if any).  The query component is indicated by the first question
   mark ("?") character and terminated by a number sign ("#") character
   or by the end of the URI.



Berners-Lee, et al.         Standards Track                    [Page 23]
 
RFC 3986                   URI Generic Syntax               January 2005


      query       = *( pchar / "/" / "?" )

   The characters slash ("/") and question mark ("?") may represent data
   within the query component.  Beware that some older, erroneous
   implementations may not handle such data correctly when it is used as
   the base URI for relative references (Section 5.1), apparently
   because they fail to distinguish query data from path data when
   looking for hierarchical separators.  However, as query components
   are often used to carry identifying information in the form of
   "key=value" pairs and one frequently used value is a reference to
   another URI, it is sometimes better for usability to avoid percent-
   encoding those characters.


3.5.  Fragment


   The fragment identifier component of a URI allows indirect
   identification of a secondary resource by reference to a primary
   resource and additional identifying information.  The identified
   secondary resource may be some portion or subset of the primary
   resource, some view on representations of the primary resource, or
   some other resource defined or described by those representations.  A
   fragment identifier component is indicated by the presence of a
   number sign ("#") character and terminated by the end of the URI.

      fragment    = *( pchar / "/" / "?" )

   The semantics of a fragment identifier are defined by the set of
   representations that might result from a retrieval action on the
   primary resource.  The fragment's format and resolution is therefore
   dependent on the media type [RFC2046] of a potentially retrieved
   representation, even though such a retrieval is only performed if the
   URI is dereferenced.  If no such representation exists, then the
   semantics of the fragment are considered unknown and are effectively
   unconstrained.  Fragment identifier semantics are independent of the
   URI scheme and thus cannot be redefined by scheme specifications.

   Individual media types may define their own restrictions on or
   structures within the fragment identifier syntax for specifying
   different types of subsets, views, or external references that are
   identifiable as secondary resources by that media type.  If the
   primary resource has multiple representations, as is often the case
   for resources whose representation is selected based on attributes of
   the retrieval request (a.k.a., content negotiation), then whatever is
   identified by the fragment should be consistent across all of those
   representations.  Each representation should either define the
   fragment so that it corresponds to the same secondary resource,
   regardless of how it is represented, or should leave the fragment
   undefined (i.e., not found).

   As with any URI, use of a fragment identifier component does not
   imply that a retrieval action will take place.  A URI with a fragment
   identifier may be used to refer to the secondary resource without any
   implication that the primary resource is accessible or will ever be
   accessed.

   Fragment identifiers have a special role in information retrieval
   systems as the primary form of client-side indirect referencing,
   allowing an author to specifically identify aspects of an existing
   resource that are only indirectly provided by the resource owner.  As
   such, the fragment identifier is not used in the scheme-specific
   processing of a URI; instead, the fragment identifier is separated
   from the rest of the URI prior to a dereference, and thus the
   identifying information within the fragment itself is dereferenced
   solely by the user agent, regardless of the URI scheme.  Although
   this separate handling is often perceived to be a loss of
   information, particularly for accurate redirection of references as
   resources move over time, it also serves to prevent information
   providers from denying reference authors the right to refer to
   information within a resource selectively.  Indirect referencing also
   provides additional flexibility and extensibility to systems that use
   URIs, as new media types are easier to define and deploy than new
   schemes of identification.

   The characters slash ("/") and question mark ("?") are allowed to
   represent data within the fragment identifier.  Beware that some
   older, erroneous implementations may not handle this data correctly
   when it is used as the base URI for relative references (Section
   5.1).


4.  Usage


   When applications make reference to a URI, they do not always use the
   full form of reference defined by the "URI" syntax rule.  To save
   space and take advantage of hierarchical locality, many Internet
   protocol elements and media type formats allow an abbreviation of a
   URI, whereas others restrict the syntax to a particular form of URI.
   We define the most common forms of reference syntax in this
   specification because they impact and depend upon the design of the
   generic syntax, requiring a uniform parsing algorithm in order to be
   interpreted consistently.


4.1.  URI Reference


   URI-reference is used to denote the most common usage of a resource
   identifier.

      URI-reference = URI / relative-ref



Berners-Lee, et al.         Standards Track                    [Page 25]
 
RFC 3986                   URI Generic Syntax               January 2005


   A URI-reference is either a URI or a relative reference.  If the
   URI-reference's prefix does not match the syntax of a scheme followed
   by its colon separator, then the URI-reference is a relative
   reference.

   A URI-reference is typically parsed first into the five URI
   components, in order to determine what components are present and
   whether the reference is relative.  Then, each component is parsed
   for its subparts and their validation.  The ABNF of URI-reference,
   along with the "first-match-wins" disambiguation rule, is sufficient
   to define a validating parser for the generic syntax.  Readers
   familiar with regular expressions should see Appendix B for an
   example of a non-validating URI-reference parser that will take any
   given string and extract the URI components.


4.2.  Relative Reference


   A relative reference takes advantage of the hierarchical syntax
   (Section 1.2.3) to express a URI reference relative to the name space
   of another hierarchical URI.

      relative-ref  = relative-part [ "?" query ] [ "#" fragment ]

      relative-part = "//" authority path-abempty
                    / path-absolute
                    / path-noscheme
                    / path-empty

   The URI referred to by a relative reference, also known as the target
   URI, is obtained by applying the reference resolution algorithm of
   Section 5.

   A relative reference that begins with two slash characters is termed
   a network-path reference; such references are rarely used.  A
   relative reference that begins with a single slash character is
   termed an absolute-path reference.  A relative reference that does
   not begin with a slash character is termed a relative-path reference.

   A path segment that contains a colon character (e.g., "this:that")
   cannot be used as the first segment of a relative-path reference, as
   it would be mistaken for a scheme name.  Such a segment must be
   preceded by a dot-segment (e.g., "./this:that") to make a relative-
   path reference.

RFC 3986                   URI Generic Syntax               January 2005



4.3.  Absolute URI


   Some protocol elements allow only the absolute form of a URI without
   a fragment identifier.  For example, defining a base URI for later
   use by relative references calls for an absolute-URI syntax rule that
   does not allow a fragment.

      absolute-URI  = scheme ":" hier-part [ "?" query ]

   URI scheme specifications must define their own syntax so that all
   strings matching their scheme-specific syntax will also match the
   <absolute-URI> grammar.  Scheme specifications will not define
   fragment identifier syntax or usage, regardless of its applicability
   to resources identifiable via that scheme, as fragment identification
   is orthogonal to scheme definition.  However, scheme specifications
   are encouraged to include a wide range of examples, including
   examples that show use of the scheme's URIs with fragment identifiers
   when such usage is appropriate.


4.4.  Same-Document Reference


   When a URI reference refers to a URI that is, aside from its fragment
   component (if any), identical to the base URI (Section 5.1), that
   reference is called a "same-document" reference.  The most frequent
   examples of same-document references are relative references that are
   empty or include only the number sign ("#") separator followed by a
   fragment identifier.

   When a same-document reference is dereferenced for a retrieval
   action, the target of that reference is defined to be within the same
   entity (representation, document, or message) as the reference;
   therefore, a dereference should not result in a new retrieval action.

   Normalization of the base and target URIs prior to their comparison,
   as described in Sections 6.2.2 and 6.2.3, is allowed but rarely
   performed in practice.  Normalization may increase the set of same-
   document references, which may be of benefit to some caching
   applications.  As such, reference authors should not assume that a
   slightly different, though equivalent, reference URI will (or will
   not) be interpreted as a same-document reference by any given
   application.


4.5.  Suffix Reference


   The URI syntax is designed for unambiguous reference to resources and
   extensibility via the URI scheme.  However, as URI identification and
   usage have become commonplace, traditional media (television, radio,
   newspapers, billboards, etc.) have increasingly used a suffix of the



Berners-Lee, et al.         Standards Track                    [Page 27]
 
RFC 3986                   URI Generic Syntax               January 2005


   URI as a reference, consisting of only the authority and path
   portions of the URI, such as

      www.w3.org/Addressing/

   or simply a DNS registered name on its own.  Such references are
   primarily intended for human interpretation rather than for machines,
   with the assumption that context-based heuristics are sufficient to
   complete the URI (e.g., most registered names beginning with "www"
   are likely to have a URI prefix of "http://").  Although there is no
   standard set of heuristics for disambiguating a URI suffix, many
   client implementations allow them to be entered by the user and
   heuristically resolved.

   Although this practice of using suffix references is common, it
   should be avoided whenever possible and should never be used in
   situations where long-term references are expected.  The heuristics
   noted above will change over time, particularly when a new URI scheme
   becomes popular, and are often incorrect when used out of context.
   Furthermore, they can lead to security issues along the lines of
   those described in [RFC1535].

   As a URI suffix has the same syntax as a relative-path reference, a
   suffix reference cannot be used in contexts where a relative
   reference is expected.  As a result, suffix references are limited to
   places where there is no defined base URI, such as dialog boxes and
   off-line advertisements.


5.  Reference Resolution


   This section defines the process of resolving a URI reference within
   a context that allows relative references so that the result is a
   string matching the <URI> syntax rule of Section 3.


5.1.  Establishing a Base URI


   The term "relative" implies that a "base URI" exists against which
   the relative reference is applied.  Aside from fragment-only
   references (Section 4.4), relative references are only usable when a
   base URI is known.  A base URI must be established by the parser
   prior to parsing URI references that might be relative.  A base URI
   must conform to the <absolute-URI> syntax rule (Section 4.3).  If the
   base URI is obtained from a URI reference, then that reference must
   be converted to absolute form and stripped of any fragment component
   prior to its use as a base URI.






Berners-Lee, et al.         Standards Track                    [Page 28]
 
RFC 3986                   URI Generic Syntax               January 2005


   The base URI of a reference can be established in one of four ways,
   discussed below in order of precedence.  The order of precedence can
   be thought of in terms of layers, where the innermost defined base
   URI has the highest precedence.  This can be visualized graphically
   as follows:

         .----------------------------------------------------------.
         |  .----------------------------------------------------.  |
         |  |  .----------------------------------------------.  |  |
         |  |  |  .----------------------------------------.  |  |  |
         |  |  |  |  .----------------------------------.  |  |  |  |
         |  |  |  |  |       <relative-reference>       |  |  |  |  |
         |  |  |  |  `----------------------------------'  |  |  |  |
         |  |  |  | (5.1.1) Base URI embedded in content   |  |  |  |
         |  |  |  `----------------------------------------'  |  |  |
         |  |  | (5.1.2) Base URI of the encapsulating entity |  |  |
         |  |  |         (message, representation, or none)   |  |  |
         |  |  `----------------------------------------------'  |  |
         |  | (5.1.3) URI used to retrieve the entity            |  |
         |  `----------------------------------------------------'  |
         | (5.1.4) Default Base URI (application-dependent)         |
         `----------------------------------------------------------'


5.1.1.  Base URI Embedded in Content


   Within certain media types, a base URI for relative references can be
   embedded within the content itself so that it can be readily obtained
   by a parser.  This can be useful for descriptive documents, such as
   tables of contents, which may be transmitted to others through
   protocols other than their usual retrieval context (e.g., email or
   USENET news).

   It is beyond the scope of this specification to specify how, for each
   media type, a base URI can be embedded.  The appropriate syntax, when
   available, is described by the data format specification associated
   with each media type.


5.1.2.  Base URI from the Encapsulating Entity


   If no base URI is embedded, the base URI is defined by the
   representation's retrieval context.  For a document that is enclosed
   within another entity, such as a message or archive, the retrieval
   context is that entity.  Thus, the default base URI of a
   representation is the base URI of the entity in which the
   representation is encapsulated.






Berners-Lee, et al.         Standards Track                    [Page 29]
 
RFC 3986                   URI Generic Syntax               January 2005


   A mechanism for embedding a base URI within MIME container types
   (e.g., the message and multipart types) is defined by MHTML
   [RFC2557].  Protocols that do not use the MIME message header syntax,
   but that do allow some form of tagged metadata to be included within
   messages, may define their own syntax for defining a base URI as part
   of a message.


5.1.3.  Base URI from the Retrieval URI


   If no base URI is embedded and the representation is not encapsulated
   within some other entity, then, if a URI was used to retrieve the
   representation, that URI shall be considered the base URI.  Note that
   if the retrieval was the result of a redirected request, the last URI
   used (i.e., the URI that resulted in the actual retrieval of the
   representation) is the base URI.


5.1.4.  Default Base URI


   If none of the conditions described above apply, then the base URI is
   defined by the context of the application.  As this definition is
   necessarily application-dependent, failing to define a base URI by
   using one of the other methods may result in the same content being
   interpreted differently by different types of applications.

   A sender of a representation containing relative references is
   responsible for ensuring that a base URI for those references can be
   established.  Aside from fragment-only references, relative
   references can only be used reliably in situations where the base URI
   is well defined.


5.2.  Relative Resolution


   This section describes an algorithm for converting a URI reference
   that might be relative to a given base URI into the parsed components
   of the reference's target.  The components can then be recomposed, as
   described in Section 5.3, to form the target URI.  This algorithm
   provides definitive results that can be used to test the output of
   other implementations.  Applications may implement relative reference
   resolution by using some other algorithm, provided that the results
   match what would be given by this one.











Berners-Lee, et al.         Standards Track                    [Page 30]
 
RFC 3986                   URI Generic Syntax               January 2005



5.2.1.  Pre-parse the Base URI


   The base URI (Base) is established according to the procedure of
   Section 5.1 and parsed into the five main components described in
   Section 3.  Note that only the scheme component is required to be
   present in a base URI; the other components may be empty or
   undefined.  A component is undefined if its associated delimiter does
   not appear in the URI reference; the path component is never
   undefined, though it may be empty.

   Normalization of the base URI, as described in Sections 6.2.2 and
   6.2.3, is optional.  A URI reference must be transformed to its
   target URI before it can be normalized.


5.2.2.  Transform References


   For each URI reference (R), the following pseudocode describes an
   algorithm for transforming R into its target URI (T):

      -- The URI reference is parsed into the five URI components
      --
      (R.scheme, R.authority, R.path, R.query, R.fragment) = parse(R);

      -- A non-strict parser may ignore a scheme in the reference
      -- if it is identical to the base URI's scheme.
      --
      if ((not strict) and (R.scheme == Base.scheme)) then
         undefine(R.scheme);
      endif;






















Berners-Lee, et al.         Standards Track                    [Page 31]
 
RFC 3986                   URI Generic Syntax               January 2005


      if defined(R.scheme) then
         T.scheme    = R.scheme;
         T.authority = R.authority;
         T.path      = remove_dot_segments(R.path);
         T.query     = R.query;
      else
         if defined(R.authority) then
            T.authority = R.authority;
            T.path      = remove_dot_segments(R.path);
            T.query     = R.query;
         else
            if (R.path == "") then
               T.path = Base.path;
               if defined(R.query) then
                  T.query = R.query;
               else
                  T.query = Base.query;
               endif;
            else
               if (R.path starts-with "/") then
                  T.path = remove_dot_segments(R.path);
               else
                  T.path = merge(Base.path, R.path);
                  T.path = remove_dot_segments(T.path);
               endif;
               T.query = R.query;
            endif;
            T.authority = Base.authority;
         endif;
         T.scheme = Base.scheme;
      endif;

      T.fragment = R.fragment;


5.2.3.  Merge Paths


   The pseudocode above refers to a "merge" routine for merging a
   relative-path reference with the path of the base URI.  This is
   accomplished as follows:

   o  If the base URI has a defined authority component and an empty
      path, then return a string consisting of "/" concatenated with the
      reference's path; otherwise,








Berners-Lee, et al.         Standards Track                    [Page 32]
 
RFC 3986                   URI Generic Syntax               January 2005


   o  return a string consisting of the reference's path component
      appended to all but the last segment of the base URI's path (i.e.,
      excluding any characters after the right-most "/" in the base URI
      path, or excluding the entire base URI path if it does not contain
      any "/" characters).


5.2.4.  Remove Dot Segments


   The pseudocode also refers to a "remove_dot_segments" routine for
   interpreting and removing the special "." and ".." complete path
   segments from a referenced path.  This is done after the path is
   extracted from a reference, whether or not the path was relative, in
   order to remove any invalid or extraneous dot-segments prior to
   forming the target URI.  Although there are many ways to accomplish
   this removal process, we describe a simple method using two string
   buffers.

   1.  The input buffer is initialized with the now-appended path
       components and the output buffer is initialized to the empty
       string.

   2.  While the input buffer is not empty, loop as follows:

       A.  If the input buffer begins with a prefix of "../" or "./",
           then remove that prefix from the input buffer; otherwise,

       B.  if the input buffer begins with a prefix of "/./" or "/.",
           where "." is a complete path segment, then replace that
           prefix with "/" in the input buffer; otherwise,

       C.  if the input buffer begins with a prefix of "/../" or "/..",
           where ".." is a complete path segment, then replace that
           prefix with "/" in the input buffer and remove the last
           segment and its preceding "/" (if any) from the output
           buffer; otherwise,

       D.  if the input buffer consists only of "." or "..", then remove
           that from the input buffer; otherwise,

       E.  move the first path segment in the input buffer to the end of
           the output buffer, including the initial "/" character (if
           any) and any subsequent characters up to, but not including,
           the next "/" character or the end of the input buffer.

   3.  Finally, the output buffer is returned as the result of
       remove_dot_segments.





Berners-Lee, et al.         Standards Track                    [Page 33]
 
RFC 3986                   URI Generic Syntax               January 2005


   Note that dot-segments are intended for use in URI references to
   express an identifier relative to the hierarchy of names in the base
   URI.  The remove_dot_segments algorithm respects that hierarchy by
   removing extra dot-segments rather than treat them as an error or
   leaving them to be misinterpreted by dereference implementations.

   The following illustrates how the above steps are applied for two
   examples of merged paths, showing the state of the two buffers after
   each step.

      STEP   OUTPUT BUFFER         INPUT BUFFER

       1 :                         /a/b/c/./../../g
       2E:   /a                    /b/c/./../../g
       2E:   /a/b                  /c/./../../g
       2E:   /a/b/c                /./../../g
       2B:   /a/b/c                /../../g
       2C:   /a/b                  /../g
       2C:   /a                    /g
       2E:   /a/g

      STEP   OUTPUT BUFFER         INPUT BUFFER

       1 :                         mid/content=5/../6
       2E:   mid                   /content=5/../6
       2E:   mid/content=5         /../6
       2C:   mid                   /6
       2E:   mid/6

   Some applications may find it more efficient to implement the
   remove_dot_segments algorithm by using two segment stacks rather than
   strings.

      Note: Beware that some older, erroneous implementations will fail
      to separate a reference's query component from its path component
      prior to merging the base and reference paths, resulting in an
      interoperability failure if the query component contains the
      strings "/../" or "/./".

RFC 3986                   URI Generic Syntax               January 2005



5.3.  Component Recomposition


   Parsed URI components can be recomposed to obtain the corresponding
   URI reference string.  Using pseudocode, this would be:

      result = ""

      if defined(scheme) then
         append scheme to result;
         append ":" to result;
      endif;

      if defined(authority) then
         append "//" to result;
         append authority to result;
      endif;

      append path to result;

      if defined(query) then
         append "?" to result;
         append query to result;
      endif;

      if defined(fragment) then
         append "#" to result;
         append fragment to result;
      endif;

      return result;

   Note that we are careful to preserve the distinction between a
   component that is undefined, meaning that its separator was not
   present in the reference, and a component that is empty, meaning that
   the separator was present and was immediately followed by the next
   component separator or the end of the reference.


5.4.  Reference Resolution Examples


   Within a representation with a well defined base URI of

      http://a/b/c/d;p?q

   a relative reference is transformed to its target URI as follows.

      "?y"            =  "http://a/b/c/d;p?y"
      "g?y"           =  "http://a/b/c/g?y"
      "#s"            =  "http://a/b/c/d;p?q#s"
      "g#s"           =  "http://a/b/c/g#s"
      "g?y#s"         =  "http://a/b/c/g?y#s"
      ";x"            =  "http://a/b/c/;x"
      "g;x"           =  "http://a/b/c/g;x"
      "g;x?y#s"       =  "http://a/b/c/g;x?y#s"
      ""              =  "http://a/b/c/d;p?q"
      "."             =  "http://a/b/c/"
      "./"            =  "http://a/b/c/"
      ".."            =  "http://a/b/"
      "../"           =  "http://a/b/"
      "../g"          =  "http://a/b/g"
      "../.."         =  "http://a/"
      "../../"        =  "http://a/"
      "../../g"       =  "http://a/g"


5.4.2.  Abnormal Examples


   Although the following abnormal examples are unlikely to occur in
   normal practice, all URI parsers should be capable of resolving them
   consistently.  Each example uses the same base as that above.

   Parsers must be careful in handling cases where there are more ".."
   segments in a relative-path reference than there are hierarchical
   levels in the base URI's path.  Note that the ".." syntax cannot be
   used to change the authority component of a URI.

      "../../../g"    =  "http://a/g"
      "../../../../g" =  "http://a/g"












Berners-Lee, et al.         Standards Track                    [Page 36]
 
RFC 3986                   URI Generic Syntax               January 2005


   Similarly, parsers must remove the dot-segments "." and ".." when
   they are complete components of a path, but not when they are only
   part of a segment.

      "/./g"          =  "http://a/g"
      "/../g"         =  "http://a/g"
      "g."            =  "http://a/b/c/g."
      ".g"            =  "http://a/b/c/.g"
      "g.."           =  "http://a/b/c/g.."
      "..g"           =  "http://a/b/c/..g"

   Less likely are cases where the relative reference uses unnecessary
   or nonsensical forms of the "." and ".." complete path segments.

      "./../g"        =  "http://a/b/g"
      "./g/."         =  "http://a/b/c/g/"
      "g/./h"         =  "http://a/b/c/g/h"
      "g/../h"        =  "http://a/b/c/h"
      "g;x=1/./y"     =  "http://a/b/c/g;x=1/y"
      "g;x=1/../y"    =  "http://a/b/c/y"

   Some applications fail to separate the reference's query and/or
   fragment components from the path component before merging it with
   the base path and removing dot-segments.  This error is rarely
   noticed, as typical usage of a fragment never includes the hierarchy
   ("/") character and the query component is not normally used within
   relative references.

      "g?y/./x"       =  "http://a/b/c/g?y/./x"
      "g?y/../x"      =  "http://a/b/c/g?y/../x"
      "g#s/./x"       =  "http://a/b/c/g#s/./x"
      "g#s/../x"      =  "http://a/b/c/g#s/../x"

   Some parsers allow the scheme name to be present in a relative
   reference if it is the same as the base URI scheme.  This is
   considered to be a loophole in prior specifications of partial URI
   [RFC1630].  Its use should be avoided but is allowed for backward
   compatibility.

      "http:g"        =  "http:g"         ; for strict parsers
                      /  "http://a/b/c/g" ; for backward compatibility

6.  Normalization and Comparison


   One of the most common operations on URIs is simple comparison:
   determining whether two URIs are equivalent without using the URIs to
   access their respective resource(s).  A comparison is performed every
   time a response cache is accessed, a browser checks its history to
   color a link, or an XML parser processes tags within a namespace.
   Extensive normalization prior to comparison of URIs is often used by
   spiders and indexing engines to prune a search space or to reduce
   duplication of request actions and response storage.

   URI comparison is performed for some particular purpose.  Protocols
   or implementations that compare URIs for different purposes will
   often be subject to differing design trade-offs in regards to how
   much effort should be spent in reducing aliased identifiers.  This
   section describes various methods that may be used to compare URIs,
   the trade-offs between them, and the types of applications that might
   use them.


6.1.  Equivalence


   Because URIs exist to identify resources, presumably they should be
   considered equivalent when they identify the same resource.  However,
   this definition of equivalence is not of much practical use, as there
   is no way for an implementation to compare two resources unless it
   has full knowledge or control of them.  For this reason,
   determination of equivalence or difference of URIs is based on string
   comparison, perhaps augmented by reference to additional rules
   provided by URI scheme definitions.  We use the terms "different" and
   "equivalent" to describe the possible outcomes of such comparisons,
   but there are many application-dependent versions of equivalence.

   Even though it is possible to determine that two URIs are equivalent,
   URI comparison is not sufficient to determine whether two URIs
   identify different resources.  For example, an owner of two different
   domain names could decide to serve the same resource from both,
   resulting in two different URIs.  Therefore, comparison methods are
   designed to minimize false negatives while strictly avoiding false
   positives.

   In testing for equivalence, applications should not directly compare
   relative references; the references should be converted to their
   respective target URIs before comparison.  When URIs are compared to
   select (or avoid) a network action, such as retrieval of a
   representation, fragment components (if any) should be excluded from
   the comparison.

RFC 3986                   URI Generic Syntax               January 2005



6.2.  Comparison Ladder


   A variety of methods are used in practice to test URI equivalence.
   These methods fall into a range, distinguished by the amount of
   processing required and the degree to which the probability of false
   negatives is reduced.  As noted above, false negatives cannot be
   eliminated.  In practice, their probability can be reduced, but this
   reduction requires more processing and is not cost-effective for all
   applications.

   If this range of comparison practices is considered as a ladder, the
   following discussion will climb the ladder, starting with practices
   that are cheap but have a relatively higher chance of producing false
   negatives, and proceeding to those that have higher computational
   cost and lower risk of false negatives.


6.2.1.  Simple String Comparison


   If two URIs, when considered as character strings, are identical,
   then it is safe to conclude that they are equivalent.  This type of
   equivalence test has very low computational cost and is in wide use
   in a variety of applications, particularly in the domain of parsing.

   Testing strings for equivalence requires some basic precautions.
   This procedure is often referred to as "bit-for-bit" or
   "byte-for-byte" comparison, which is potentially misleading.  Testing
   strings for equality is normally based on pair comparison of the
   characters that make up the strings, starting from the first and
   proceeding until both strings are exhausted and all characters are
   found to be equal, until a pair of characters compares unequal, or
   until one of the strings is exhausted before the other.

   This character comparison requires that each pair of characters be
   put in comparable form.  For example, should one URI be stored in a
   byte array in EBCDIC encoding and the second in a Java String object
   (UTF-16), bit-for-bit comparisons applied naively will produce
   errors.  It is better to speak of equality on a character-for-
   character basis rather than on a byte-for-byte or bit-for-bit basis.
   In practical terms, character-by-character comparisons should be done
   codepoint-by-codepoint after conversion to a common character
   encoding.

   False negatives are caused by the production and use of URI aliases.
   Unnecessary aliases can be reduced, regardless of the comparison
   method, by consistently providing URI references in an already-
   normalized form (i.e., a form identical to what would be produced
   after normalization is applied, as described below).




Berners-Lee, et al.         Standards Track                    [Page 39]
 
RFC 3986                   URI Generic Syntax               January 2005


   Protocols and data formats often limit some URI comparisons to simple
   string comparison, based on the theory that people and
   implementations will, in their own best interest, be consistent in
   providing URI references, or at least consistent enough to negate any
   efficiency that might be obtained from further normalization.


6.2.2.  Syntax-Based Normalization


   Implementations may use logic based on the definitions provided by
   this specification to reduce the probability of false negatives.
   This processing is moderately higher in cost than character-for-
   character string comparison.  For example, an application using this
   approach could reasonably consider the following two URIs equivalent:

      example://a/b/c/%7Bfoo%7D
      eXAMPLE://a/./b/../b/%63/%7bfoo%7d

   Web user agents, such as browsers, typically apply this type of URI
   normalization when determining whether a cached response is
   available.  Syntax-based normalization includes such techniques as
   case normalization, percent-encoding normalization, and removal of
   dot-segments.


6.2.2.1.  Case Normalization


   For all URIs, the hexadecimal digits within a percent-encoding
   triplet (e.g., "%3a" versus "%3A") are case-insensitive and therefore
   should be normalized to use uppercase letters for the digits A-F.

   When a URI uses components of the generic syntax, the component
   syntax equivalence rules always apply; namely, that the scheme and
   host are case-insensitive and therefore should be normalized to
   lowercase.  For example, the URI <HTTP://www.EXAMPLE.com/> is
   equivalent to <http://www.example.com/>.  The other generic syntax
   components are assumed to be case-sensitive unless specifically
   defined otherwise by the scheme (see Section 6.2.3).


6.2.2.2.  Percent-Encoding Normalization


   The percent-encoding mechanism (Section 2.1) is a frequent source of
   variance among otherwise identical URIs.  In addition to the case
   normalization issue noted above, some URI producers percent-encode
   octets that do not require percent-encoding, resulting in URIs that
   are equivalent to their non-encoded counterparts.  These URIs should
   be normalized by decoding any percent-encoded octet that corresponds
   to an unreserved character, as described in Section 2.3.

RFC 3986                   URI Generic Syntax               January 2005



6.2.2.3.  Path Segment Normalization


   The complete path segments "." and ".." are intended only for use
   within relative references (Section 4.1) and are removed as part of
   the reference resolution process (Section 5.2).  However, some
   deployed implementations incorrectly assume that reference resolution
   is not necessary when the reference is already a URI and thus fail to
   remove dot-segments when they occur in non-relative paths.  URI
   normalizers should remove dot-segments by applying the
   remove_dot_segments algorithm to the path, as described in
   Section 5.2.4.


6.2.3.  Scheme-Based Normalization


   The syntax and semantics of URIs vary from scheme to scheme, as
   described by the defining specification for each scheme.
   Implementations may use scheme-specific rules, at further processing
   cost, to reduce the probability of false negatives.  For example,
   because the "http" scheme makes use of an authority component, has a
   default port of "80", and defines an empty path to be equivalent to
   "/", the following four URIs are equivalent:

      http://example.com
      http://example.com/
      http://example.com:/
      http://example.com:80/

   In general, a URI that uses the generic syntax for authority with an
   empty path should be normalized to a path of "/".  Likewise, an
   explicit ":port", for which the port is empty or the default for the
   scheme, is equivalent to one where the port and its ":" delimiter are
   elided and thus should be removed by scheme-based normalization.  For
   example, the second URI above is the normal form for the "http"
   scheme.

   Another case where normalization varies by scheme is in the handling
   of an empty authority component or empty host subcomponent.  For many
   scheme specifications, an empty authority or host is considered an
   error; for others, it is considered equivalent to "localhost" or the
   end-user's host.  When a scheme defines a default for authority and a
   URI reference to that default is desired, the reference should be
   normalized to an empty authority for the sake of uniformity, brevity,
   and internationalization.  If, however, either the userinfo or port
   subcomponents are non-empty, then the host should be given explicitly
   even if it matches the default.

   Normalization should not remove delimiters when their associated
   component is empty unless licensed to do so by the scheme



Berners-Lee, et al.         Standards Track                    [Page 41]
 
RFC 3986                   URI Generic Syntax               January 2005


   specification.  For example, the URI "http://example.com/?" cannot be
   assumed to be equivalent to any of the examples above.  Likewise, the
   presence or absence of delimiters within a userinfo subcomponent is
   usually significant to its interpretation.  The fragment component is
   not subject to any scheme-based normalization; thus, two URIs that
   differ only by the suffix "#" are considered different regardless of
   the scheme.

   Some schemes define additional subcomponents that consist of case-
   insensitive data, giving an implicit license to normalizers to
   convert this data to a common case (e.g., all lowercase).  For
   example, URI schemes that define a subcomponent of path to contain an
   Internet hostname, such as the "mailto" URI scheme, cause that
   subcomponent to be case-insensitive and thus subject to case
   normalization (e.g., "mailto:Joe@Example.COM" is equivalent to
   "mailto:Joe@example.com", even though the generic syntax considers
   the path component to be case-sensitive).

   Other scheme-specific normalizations are possible.


6.2.4.  Protocol-Based Normalization


   Substantial effort to reduce the incidence of false negatives is
   often cost-effective for web spiders.  Therefore, they implement even
   more aggressive techniques in URI comparison.  For example, if they
   observe that a URI such as

      http://example.com/data

   redirects to a URI differing only in the trailing slash

      http://example.com/data/

   they will likely regard the two as equivalent in the future.  This
   kind of technique is only appropriate when equivalence is clearly
   indicated by both the result of accessing the resources and the
   common conventions of their scheme's dereference algorithm (in this
   case, use of redirection by HTTP origin servers to avoid problems
   with relative references).

7.  Security Considerations


   A URI does not in itself pose a security threat.  However, as URIs
   are often used to provide a compact set of instructions for access to
   network resources, care must be taken to properly interpret the data
   within a URI, to prevent that data from causing unintended access,
   and to avoid including data that should not be revealed in plain
   text.


7.1.  Reliability and Consistency


   There is no guarantee that once a URI has been used to retrieve
   information, the same information will be retrievable by that URI in
   the future.  Nor is there any guarantee that the information
   retrievable via that URI in the future will be observably similar to
   that retrieved in the past.  The URI syntax does not constrain how a
   given scheme or authority apportions its namespace or maintains it
   over time.  Such guarantees can only be obtained from the person(s)
   controlling that namespace and the resource in question.  A specific
   URI scheme may define additional semantics, such as name persistence,
   if those semantics are required of all naming authorities for that
   scheme.


7.2.  Malicious Construction


   It is sometimes possible to construct a URI so that an attempt to
   perform a seemingly harmless, idempotent operation, such as the
   retrieval of a representation, will in fact cause a possibly damaging
   remote operation.  The unsafe URI is typically constructed by
   specifying a port number other than that reserved for the network
   protocol in question.  The client unwittingly contacts a site running
   a different protocol service, and data within the URI contains
   instructions that, when interpreted according to this other protocol,
   cause an unexpected operation.  A frequent example of such abuse has
   been the use of a protocol-based scheme with a port component of
   "25", thereby fooling user agent software into sending an unintended
   or impersonating message via an SMTP server.

   Applications should prevent dereference of a URI that specifies a TCP
   port number within the "well-known port" range (0 - 1023) unless the
   protocol being used to dereference that URI is compatible with the
   protocol expected on that well-known port.  Although IANA maintains a
   registry of well-known ports, applications should make such
   restrictions user-configurable to avoid preventing the deployment of
   new services.






Berners-Lee, et al.         Standards Track                    [Page 43]
 
RFC 3986                   URI Generic Syntax               January 2005


   When a URI contains percent-encoded octets that match the delimiters
   for a given resolution or dereference protocol (for example, CR and
   LF characters for the TELNET protocol), these percent-encodings must
   not be decoded before transmission across that protocol.  Transfer of
   the percent-encoding, which might violate the protocol, is less
   harmful than allowing decoded octets to be interpreted as additional
   operations or parameters, perhaps triggering an unexpected and
   possibly harmful remote operation.


7.3.  Back-End Transcoding


   When a URI is dereferenced, the data within it is often parsed by
   both the user agent and one or more servers.  In HTTP, for example, a
   typical user agent will parse a URI into its five major components,
   access the authority's server, and send it the data within the
   authority, path, and query components.  A typical server will take
   that information, parse the path into segments and the query into
   key/value pairs, and then invoke implementation-specific handlers to
   respond to the request.  As a result, a common security concern for
   server implementations that handle a URI, either as a whole or split
   into separate components, is proper interpretation of the octet data
   represented by the characters and percent-encodings within that URI.

   Percent-encoded octets must be decoded at some point during the
   dereference process.  Applications must split the URI into its
   components and subcomponents prior to decoding the octets, as
   otherwise the decoded octets might be mistaken for delimiters.
   Security checks of the data within a URI should be applied after
   decoding the octets.  Note, however, that the "%00" percent-encoding
   (NUL) may require special handling and should be rejected if the
   application is not expecting to receive raw data within a component.

   Special care should be taken when the URI path interpretation process
   involves the use of a back-end file system or related system
   functions.  File systems typically assign an operational meaning to
   special characters, such as the "/", "\", ":", "[", and "]"
   characters, and to special device names like ".", "..", "...", "aux",
   "lpt", etc.  In some cases, merely testing for the existence of such
   a name will cause the operating system to pause or invoke unrelated
   system calls, leading to significant security concerns regarding
   denial of service and unintended data transfer.  It would be
   impossible for this specification to list all such significant
   characters and device names.  Implementers should research the
   reserved names and characters for the types of storage device that
   may be attached to their applications and restrict the use of data
   obtained from URI components accordingly.

RFC 3986                   URI Generic Syntax               January 2005



7.4.  Rare IP Address Formats


   Although the URI syntax for IPv4address only allows the common
   dotted-decimal form of IPv4 address literal, many implementations
   that process URIs make use of platform-dependent system routines,
   such as gethostbyname() and inet_aton(), to translate the string
   literal to an actual IP address.  Unfortunately, such system routines
   often allow and process a much larger set of formats than those
   described in Section 3.2.2.

   For example, many implementations allow dotted forms of three
   numbers, wherein the last part is interpreted as a 16-bit quantity
   and placed in the right-most two bytes of the network address (e.g.,
   a Class B network).  Likewise, a dotted form of two numbers means
   that the last part is interpreted as a 24-bit quantity and placed in
   the right-most three bytes of the network address (Class A), and a
   single number (without dots) is interpreted as a 32-bit quantity and
   stored directly in the network address.  Adding further to the
   confusion, some implementations allow each dotted part to be
   interpreted as decimal, octal, or hexadecimal, as specified in the C
   language (i.e., a leading 0x or 0X implies hexadecimal; a leading 0
   implies octal; otherwise, the number is interpreted as decimal).

   These additional IP address formats are not allowed in the URI syntax
   due to differences between platform implementations.  However, they
   can become a security concern if an application attempts to filter
   access to resources based on the IP address in string literal format.
   If this filtering is performed, literals should be converted to
   numeric form and filtered based on the numeric value, and not on a
   prefix or suffix of the string form.


7.5.  Sensitive Information


   URI producers should not provide a URI that contains a username or
   password that is intended to be secret.  URIs are frequently
   displayed by browsers, stored in clear text bookmarks, and logged by
   user agent history and intermediary applications (proxies).  A
   password appearing within the userinfo component is deprecated and
   should be considered an error (or simply ignored) except in those
   rare cases where the 'password' parameter is intended to be public.


7.6.  Semantic Attacks


   Because the userinfo subcomponent is rarely used and appears before
   the host in the authority component, it can be used to construct a
   URI intended to mislead a human user by appearing to identify one
   (trusted) naming authority while actually identifying a different
   authority hidden behind the noise.  For example



Berners-Lee, et al.         Standards Track                    [Page 45]
 
RFC 3986                   URI Generic Syntax               January 2005


      ftp://cnn.example.com&story=breaking_news@10.0.0.1/top_story.htm

   might lead a human user to assume that the host is 'cnn.example.com',
   whereas it is actually '10.0.0.1'.  Note that a misleading userinfo
   subcomponent could be much longer than the example above.

   A misleading URI, such as that above, is an attack on the user's
   preconceived notions about the meaning of a URI rather than an attack
   on the software itself.  User agents may be able to reduce the impact
   of such attacks by distinguishing the various components of the URI
   when they are rendered, such as by using a different color or tone to
   render userinfo if any is present, though there is no panacea.  More
   information on URI-based semantic attacks can be found in [Siedzik].


8.  IANA Considerations


   URI scheme names, as defined by <scheme> in Section 3.1, form a
   registered namespace that is managed by IANA according to the
   procedures defined in [BCP35].  No IANA actions are required by this
   document.

Appendix B.  Parsing a URI Reference with a Regular Expression

   As the "first-match-wins" algorithm is identical to the "greedy"
   disambiguation method used by POSIX regular expressions, it is
   natural and commonplace to use a regular expression for parsing the
   potential five components of a URI reference.

   The following line is the regular expression for breaking-down a
   well-formed URI reference into its components.

RFC 3986                   URI Generic Syntax               January 2005


      ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
       12            3  4          5       6  7        8 9

   The numbers in the second line above are only to assist readability;
   they indicate the reference points for each subexpression (i.e., each
   paired parenthesis).  We refer to the value matched for subexpression
   <n> as $<n>.  For example, matching the above expression to

      http://www.ics.uci.edu/pub/ietf/uri/#Related

   results in the following subexpression matches:

      $1 = http:
      $2 = http
      $3 = //www.ics.uci.edu
      $4 = www.ics.uci.edu
      $5 = /pub/ietf/uri/
      $6 = <undefined>
      $7 = <undefined>
      $8 = #Related
      $9 = Related

   where <undefined> indicates that the component is not present, as is
   the case for the query component in the above example.  Therefore, we
   can determine the value of the five components as

      scheme    = $2
      authority = $4
      path      = $5
      query     = $7
      fragment  = $9

   Going in the opposite direction, we can recreate a URI reference from
   its components by using the algorithm of Section 5.3.

Appendix C.  Delimiting a URI in Context

   URIs are often transmitted through formats that do not provide a
   clear context for their interpretation.  For example, there are many
   occasions when a URI is included in plain text; examples include text
   sent in email, USENET news, and on printed paper.  In such cases, it
   is important to be able to delimit the URI from the rest of the text,
   and in particular from punctuation marks that might be mistaken for
   part of the URI.

   In practice, URIs are delimited in a variety of ways, but usually
   within double-quotes "http://example.com/", angle brackets
   <http://example.com/>, or just by using whitespace:



Berners-Lee, et al.         Standards Track                    [Page 51]
 
RFC 3986                   URI Generic Syntax               January 2005


      http://example.com/

   These wrappers do not form part of the URI.

   In some cases, extra whitespace (spaces, line-breaks, tabs, etc.) may
   have to be added to break a long URI across lines.  The whitespace
   should be ignored when the URI is extracted.

   No whitespace should be introduced after a hyphen ("-") character.
   Because some typesetters and printers may (erroneously) introduce a
   hyphen at the end of line when breaking it, the interpreter of a URI
   containing a line break immediately after a hyphen should ignore all
   whitespace around the line break and should be aware that the hyphen
   may or may not actually be part of the URI.

   Using <> angle brackets around each URI is especially recommended as
   a delimiting style for a reference that contains embedded whitespace.

   The prefix "URL:" (with or without a trailing space) was formerly
   recommended as a way to help distinguish a URI from other bracketed
   designators, though it is not commonly used in practice and is no
   longer recommended.

   For robustness, software that accepts user-typed URI should attempt
   to recognize and strip both delimiters and embedded whitespace.

   For example, the text

      Yes, Jim, I found it under "http://www.w3.org/Addressing/",
      but you can probably pick it up from <ftp://foo.example.
      http://www.ics.uci.edu/pub/
      ietf/uri/historical.html#WARNING>.

   contains the URI references

      http://www.w3.org/Addressing/
      ftp://foo.example.com/rfc/
      http://www.ics.uci.edu/pub/ietf/uri/historical.html#WARNING

RFC 3986                   URI Generic Syntax               January 2005


Appendix D.  Changes from RFC 2396

D.1.  Additions

   An ABNF rule for URI has been introduced to correspond to one common
   usage of the term: an absolute URI with optional fragment.

   IPv6 (and later) literals have been added to the list of possible
   identifiers for the host portion of an authority component, as
   described by [RFC2732], with the addition of "[" and "]" to the
   reserved set and a version flag to anticipate future versions of IP
   literals.  Square brackets are now specified as reserved within the
   authority component and are not allowed outside their use as
   delimiters for an IP literal within host.  In order to make this
   change without changing the technical definition of the path, query,
   and fragment components, those rules were redefined to directly
   specify the characters allowed.

   As [RFC2732] defers to [RFC3513] for definition of an IPv6 literal
   address, which, unfortunately, lacks an ABNF description of
   IPv6address, we created a new ABNF rule for IPv6address that matches
   the text representations defined by Section 2.2 of [RFC3513].
   Likewise, the definition of IPv4address has been improved in order to
   limit each decimal octet to the range 0-255.

   Section 6, on URI normalization and comparison, has been completely
   rewritten and extended by using input from Tim Bray and discussion
   within the W3C Technical Architecture Group.

D.2.  Modifications

   The ad-hoc BNF syntax of RFC 2396 has been replaced with the ABNF of
   [RFC2234].  This change required all rule names that formerly
   included underscore characters to be renamed with a dash instead.  In
   addition, a number of syntax rules have been eliminated or simplified
   to make the overall grammar more comprehensible.  Specifications that
   refer to the obsolete grammar rules may be understood by replacing
   those rules according to the following table:

   Use of the above obsolete rules for the definition of scheme-specific
   syntax is deprecated.

   Section 2, on characters, has been rewritten to explain what
   characters are reserved, when they are reserved, and why they are
   reserved, even when they are not used as delimiters by the generic
   syntax.  The mark characters that are typically unsafe to decode,
   including the exclamation mark ("!"), asterisk ("*"), single-quote
   ("'"), and open and close parentheses ("(" and ")"), have been moved
   to the reserved set in order to clarify the distinction between
   reserved and unreserved and, hopefully, to answer the most common
   question of scheme designers.  Likewise, the section on
   percent-encoded characters has been rewritten, and URI normalizers

RFC 3986                   URI Generic Syntax               January 2005


   corresponding to unreserved characters.  In general, the terms
   "escaped" and "unescaped" have been replaced with "percent-encoded"
   and "decoded", respectively, to reduce confusion with other forms of
   escape mechanisms.

   The ABNF for URI and URI-reference has been redesigned to make them
   more friendly to LALR parsers and to reduce complexity.  As a result,
   the layout form of syntax description has been removed, along with
   the uric, uric_no_slash, opaque_part, net_path, abs_path, rel_path,
   path_segments, rel_segment, and mark rules.  All references to
   "opaque" URIs have been replaced with a better description of how the
   path component may be opaque to hierarchy.  The relativeURI rule has
   been replaced with relative-ref to avoid unnecessary confusion over
   whether they are a subset of URI.  The ambiguity regarding the
   parsing of URI-reference as a URI or a relative-ref with a colon in
   the first segment has been eliminated through the use of five
   separate path matching rules.

   The fragment identifier has been moved back into the section on
   generic syntax components and within the URI and relative-ref rules,
   though it remains excluded from absolute-URI.  The number sign ("#")
   character has been moved back to the reserved set as a result of
   reintegrating the fragment syntax.

   The ABNF has been corrected to allow the path component to be empty.
   This also allows an absolute-URI to consist of nothing after the
   "scheme:", as is present in practice with the "dav:" namespace
   [RFC2518] and with the "about:" scheme used internally by many WWW
   browser implementations.  The ambiguity regarding the boundary
   between authority and path has been eliminated through the use of
   five separate path matching rules.

   Registry-based naming authorities that use the generic syntax are now
   defined within the host rule.  This change allows current
   implementations, where whatever name provided is simply fed to the
   local name resolution mechanism, to be consistent with the
   specification.  It also removes the need to re-specify DNS name
   formats here.  Furthermore, it allows the host component to contain
   percent-encoded octets, which is necessary to enable
   internationalized domain names to be provided in URIs, processed in
   their native character encodings at the application layers above URI
   processing, and passed to an IDNA library as a registered name in the
   UTF-8 character encoding.  The server, hostport, hostname,
   domainlabel, toplabel, and alphanum rules have been removed.

   The resolving relative references algorithm of [RFC2396] has been
   rewritten with pseudocode for this revision to improve clarity and
   fix the following issues:

RFC 3986                   URI Generic Syntax               January 2005


   o  [RFC2396] section 5.2, step 6a, failed to account for a base URI
      with no path.

   o  Restored the behavior of [RFC1808] where, if the reference
      contains an empty path and a defined query component, the target
      URI inherits the base URI's path component.

   o  The determination of whether a URI reference is a same-document
      reference has been decoupled from the URI parser, simplifying the
      URI processing interface within applications in a way consistent
      with the internal architecture of deployed URI processing
      implementations.  The determination is now based on comparison to
      the base URI after transforming a reference to absolute form,
      rather than on the format of the reference itself.  This change
      may result in more references being considered "same-document"
      under this specification than there would be under the rules given
      in RFC 2396, especially when normalization is used to reduce
      aliases.  However, it does not change the status of existing
      same-document references.

   o  Separated the path merge routine into two routines: merge, for
      describing combination of the base URI path with a relative-path
      reference, and remove_dot_segments, for describing how to remove
      the special "." and ".." segments from a composed path.  The
      remove_dot_segments algorithm is now applied to all URI reference
      paths in order to match common implementations and to improve the
      normalization of URIs in practice.  This change only impacts the
      parsing of abnormal references and same-scheme references wherein
      the base URI has a non-hierarchical path.

1.  Introduction


   This specification defines the addressing architecture of the IP
   Version 6 (IPv6) protocol.  It includes the basic formats for the
   various types of IPv6 addresses (unicast, anycast, and multicast).

2. IPv6 Addressing


   IPv6 addresses are 128-bit identifiers for interfaces and sets of
   interfaces (where "interface" is as defined in section 2 of [IPV6]).
   There are three types of addresses:

   Unicast:   An identifier for a single interface.  A packet sent to a
              unicast address is delivered to the interface identified
              by that address.

   Anycast:   An identifier for a set of interfaces (typically belonging
              to different nodes).  A packet sent to an anycast address
              is delivered to one of the interfaces identified by that
              address (the "nearest" one, according to the routing
              protocols' measure of distance).

   Multicast: An identifier for a set of interfaces (typically belonging
              to different nodes).  A packet sent to a multicast address
              is delivered to all interfaces identified by that address.

   There are no broadcast addresses in IPv6, their function being
   superseded by multicast addresses.

   In this document, fields in addresses are given a specific name, for
   example "subnet".  When this name is used with the term "ID" for
   identifier after the name (e.g., "subnet ID"), it refers to the
   contents of the named field.  When it is used with the term "prefix"
   (e.g., "subnet prefix") it refers to all of the address from the left
   up to and including this field.

   In IPv6, all zeros and all ones are legal values for any field,
   unless specifically excluded.  Specifically, prefixes may contain, or
   end with, zero-valued fields.

2.1 Addressing Model


   IPv6 addresses of all types are assigned to interfaces, not nodes.
   An IPv6 unicast address refers to a single interface.  Since each
   interface belongs to a single node, any of that node's interfaces'
   unicast addresses may be used as an identifier for the node.

   All interfaces are required to have at least one link-local unicast
   address (see section 2.8 for additional required addresses).  A
   single interface may also have multiple IPv6 addresses of any type
   (unicast, anycast, and multicast) or scope.  Unicast addresses with
   scope greater than link-scope are not needed for interfaces that are
   not used as the origin or destination of any IPv6 packets to or from
   non-neighbors.  This is sometimes convenient for point-to-point
   interfaces.  There is one exception to this addressing model:

      A unicast address or a set of unicast addresses may be assigned to
      multiple physical interfaces if the implementation treats the
      multiple physical interfaces as one interface when presenting it
      to the internet layer.  This is useful for load-sharing over
      multiple physical interfaces.

   Currently IPv6 continues the IPv4 model that a subnet prefix is
   associated with one link.  Multiple subnet prefixes may be assigned
   to the same link.


2.2 Text Representation of Addresses


   There are three conventional forms for representing IPv6 addresses as
   text strings:

   1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are the
      hexadecimal values of the eight 16-bit pieces of the address.

      Examples:

         FEDC:BA98:7654:3210:FEDC:BA98:7654:3210

         1080:0:0:0:8:800:200C:417A

      Note that it is not necessary to write the leading zeros in an
      individual field, but there must be at least one numeral in every
      field (except for the case described in 2.).

   2. Due to some methods of allocating certain styles of IPv6
      addresses, it will be common for addresses to contain long strings
      of zero bits.  In order to make writing addresses containing zero
      bits easier a special syntax is available to compress the zeros.



Hinden & Deering            Standards Track                     [Page 4]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


      The use of "::" indicates one or more groups of 16 bits of zeros.
      The "::" can only appear once in an address.  The "::" can also be
      used to compress leading or trailing zeros in an address.

      For example, the following addresses:

         1080:0:0:0:8:800:200C:417A  a unicast address
         FF01:0:0:0:0:0:0:101        a multicast address
         0:0:0:0:0:0:0:1             the loopback address
         0:0:0:0:0:0:0:0             the unspecified addresses

      may be represented as:

         1080::8:800:200C:417A       a unicast address
         FF01::101                   a multicast address
         ::1                         the loopback address
         ::                          the unspecified addresses

   3. An alternative form that is sometimes more convenient when dealing
      with a mixed environment of IPv4 and IPv6 nodes is
      x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values of
      the six high-order 16-bit pieces of the address, and the 'd's are
      the decimal values of the four low-order 8-bit pieces of the
      address (standard IPv4 representation).  Examples:

         0:0:0:0:0:0:13.1.68.3

         0:0:0:0:0:FFFF:129.144.52.38

      or in compressed form:

         ::13.1.68.3

         ::FFFF:129.144.52.38


2.3 Text Representation of Address Prefixes


   The text representation of IPv6 address prefixes is similar to the
   way IPv4 addresses prefixes are written in CIDR notation [CIDR].  An
   IPv6 address prefix is represented by the notation:

      ipv6-address/prefix-length

   where

      ipv6-address    is an IPv6 address in any of the notations listed
                      in section 2.2.




Hinden & Deering            Standards Track                     [Page 5]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


      prefix-length   is a decimal value specifying how many of the
                      leftmost contiguous bits of the address comprise
                      the prefix.

   For example, the following are legal representations of the 60-bit
   prefix 12AB00000000CD3 (hexadecimal):

      12AB:0000:0000:CD30:0000:0000:0000:0000/60
      12AB::CD30:0:0:0:0/60
      12AB:0:0:CD30::/60

   The following are NOT legal representations of the above prefix:

      12AB:0:0:CD3/60   may drop leading zeros, but not trailing zeros,
                        within any 16-bit chunk of the address

      12AB::CD30/60     address to left of "/" expands to
                        12AB:0000:0000:0000:0000:000:0000:CD30

      12AB::CD3/60      address to left of "/" expands to
                        12AB:0000:0000:0000:0000:000:0000:0CD3

   When writing both a node address and a prefix of that node address
   (e.g., the node's subnet prefix), the two can combined as follows:

      the node address      12AB:0:0:CD30:123:4567:89AB:CDEF
      and its subnet number 12AB:0:0:CD30::/60

      can be abbreviated as 12AB:0:0:CD30:123:4567:89AB:CDEF/60

2.4 Address Type Identification

   The type of an IPv6 address is identified by the high-order bits of
   the address, as follows:

   Address type         Binary prefix        IPv6 notation   Section
   ------------         -------------        -------------   -------
   Unspecified          00...0  (128 bits)   ::/128          2.5.2
   Loopback             00...1  (128 bits)   ::1/128         2.5.3
   Multicast            11111111             FF00::/8        2.7
   Link-local unicast   1111111010           FE80::/10       2.5.6
   Site-local unicast   1111111011           FEC0::/10       2.5.6
   Global unicast       (everything else)

   Anycast addresses are taken from the unicast address spaces (of any
   scope) and are not syntactically distinguishable from unicast
   addresses.




Hinden & Deering            Standards Track                     [Page 6]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   The general format of global unicast addresses is described in
   section 2.5.4.  Some special-purpose subtypes of global unicast
   addresses which contain embedded IPv4 addresses (for the purposes of
   IPv4-IPv6 interoperation) are described in section 2.5.5.

   Future specifications may redefine one or more sub-ranges of the
   global unicast space for other purposes, but unless and until that
   happens, implementations must treat all addresses that do not start
   with any of the above-listed prefixes as global unicast addresses.


2.5 Unicast Addresses


   IPv6 unicast addresses are aggregable with prefixes of arbitrary
   bit-length similar to IPv4 addresses under Classless Interdomain
   Routing.

   There are several types of unicast addresses in IPv6, in particular
   global unicast, site-local unicast, and link-local unicast.  There
   are also some special-purpose subtypes of global unicast, such as
   IPv6 addresses with embedded IPv4 addresses or encoded NSAP
   addresses.  Additional address types or subtypes can be defined in
   the future.

   IPv6 nodes may have considerable or little knowledge of the internal
   structure of the IPv6 address, depending on the role the node plays
   (for instance, host versus router).  At a minimum, a node may
   consider that unicast addresses (including its own) have no internal
   structure:

   |                           128 bits                              |
   +-----------------------------------------------------------------+
   |                          node address                           |
   +-----------------------------------------------------------------+

   A slightly sophisticated host (but still rather simple) may
   additionally be aware of subnet prefix(es) for the link(s) it is
   attached to, where different addresses may have different values for
   n:

   |                         n bits                 |   128-n bits   |
   +------------------------------------------------+----------------+
   |                   subnet prefix                | interface ID   |
   +------------------------------------------------+----------------+

   Though a very simple router may have no knowledge of the internal
   structure of IPv6 unicast addresses, routers will more generally have
   knowledge of one or more of the hierarchical boundaries for the
   operation of routing protocols.  The known boundaries will differ



Hinden & Deering            Standards Track                     [Page 7]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   from router to router, depending on what positions the router holds
   in the routing hierarchy.


2.5.1 Interface Identifiers


   Interface identifiers in IPv6 unicast addresses are used to identify
   interfaces on a link.  They are required to be unique within a subnet
   prefix.  It is recommended that the same interface identifier not be
   assigned to different nodes on a link.  They may also be unique over
   a broader scope.  In some cases an interface's identifier will be
   derived directly from that interface's link-layer address.  The same
   interface identifier may be used on multiple interfaces on a single
   node, as long as they are attached to different subnets.

   Note that the uniqueness of interface identifiers is independent of
   the uniqueness of IPv6 addresses.  For example, a global unicast
   address may be created with a non-global scope interface identifier
   and a site-local address may be created with a global scope interface
   identifier.

   For all unicast addresses, except those that start with binary value
   000, Interface IDs are required to be 64 bits long and to be
   constructed in Modified EUI-64 format.

   Modified EUI-64 format based Interface identifiers may have global
   scope when derived from a global token (e.g., IEEE 802 48-bit MAC or
   IEEE EUI-64 identifiers [EUI64]) or may have local scope where a
   global token is not available (e.g., serial links, tunnel end-points,
   etc.) or where global tokens are undesirable (e.g., temporary tokens
   for privacy [PRIV]).

   Modified EUI-64 format interface identifiers are formed by inverting
   the "u" bit (universal/local bit in IEEE EUI-64 terminology) when
   forming the interface identifier from IEEE EUI-64 identifiers.  In
   the resulting Modified EUI-64 format the "u" bit is set to one (1) to
   indicate global scope, and it is set to zero (0) to indicate local
   scope.  The first three octets in binary of an IEEE EUI-64 identifier
   are as follows:

       0       0 0       1 1       2
      |0       7 8       5 6       3|
      +----+----+----+----+----+----+
      |cccc|ccug|cccc|cccc|cccc|cccc|
      +----+----+----+----+----+----+

   written in Internet standard bit-order , where "u" is the
   universal/local bit, "g" is the individual/group bit, and "c" are the
   bits of the company_id.  Appendix A: "Creating Modified EUI-64 format



Hinden & Deering            Standards Track                     [Page 8]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   Interface Identifiers" provides examples on the creation of Modified
   EUI-64 format based interface identifiers.

   The motivation for inverting the "u" bit when forming an interface
   identifier is to make it easy for system administrators to hand
   configure non-global identifiers when hardware tokens are not
   available.  This is expected to be case for serial links, tunnel end-
   points, etc.  The alternative would have been for these to be of the
   form 0200:0:0:1, 0200:0:0:2, etc., instead of the much simpler 1, 2,
   etc.

   The use of the universal/local bit in the Modified EUI-64 format
   identifier is to allow development of future technology that can take
   advantage of interface identifiers with global scope.

   The details of forming interface identifiers are defined in the
   appropriate "IPv6 over <link>" specification such as "IPv6 over
   Ethernet" [ETHER], "IPv6 over FDDI" [FDDI], etc.


2.5.2 The Unspecified Address


   The address 0:0:0:0:0:0:0:0 is called the unspecified address.  It
   must never be assigned to any node.  It indicates the absence of an
   address.  One example of its use is in the Source Address field of
   any IPv6 packets sent by an initializing host before it has learned
   its own address.

   The unspecified address must not be used as the destination address
   of IPv6 packets or in IPv6 Routing Headers.  An IPv6 packet with a
   source address of unspecified must never be forwarded by an IPv6
   router.


2.5.3 The Loopback Address


   The unicast address 0:0:0:0:0:0:0:1 is called the loopback address.
   It may be used by a node to send an IPv6 packet to itself.  It may
   never be assigned to any physical interface.   It is treated as
   having link-local scope, and may be thought of as the link-local
   unicast address of a virtual interface (typically called "the
   loopback interface") to an imaginary link that goes nowhere.

   The loopback address must not be used as the source address in IPv6
   packets that are sent outside of a single node.  An IPv6 packet with
   a destination address of loopback must never be sent outside of a
   single node and must never be forwarded by an IPv6 router.  A packet
   received on an interface with destination address of loopback must be
   dropped.

RFC 3513              IPv6 Addressing Architecture            April 2003



2.5.4 Global Unicast Addresses


   The general format for IPv6 global unicast addresses is as follows:

   |         n bits         |   m bits  |       128-n-m bits         |
   +------------------------+-----------+----------------------------+
   | global routing prefix  | subnet ID |       interface ID         |
   +------------------------+-----------+----------------------------+

   where the global routing prefix is a (typically hierarchically-
   structured) value assigned to a site (a cluster of subnets/links),
   the subnet ID is an identifier of a link within the site, and the
   interface ID is as defined in section 2.5.1.

   All global unicast addresses other than those that start with binary
   000 have a 64-bit interface ID field (i.e., n + m = 64), formatted as
   described in section 2.5.1.  Global unicast addresses that start with
   binary 000 have no such constraint on the size or structure of the
   interface ID field.

   Examples of global unicast addresses that start with binary 000 are
   the IPv6 address with embedded IPv4 addresses described in section
   2.5.5 and the IPv6 address containing encoded NSAP addresses
   specified in [NSAP].  An example of global addresses starting with a
   binary value other than 000 (and therefore having a 64-bit interface
   ID field) can be found in [AGGR].


2.5.5 IPv6 Addresses with Embedded IPv4 Addresses


   The IPv6 transition mechanisms [TRAN] include a technique for hosts
   and routers to dynamically tunnel IPv6 packets over IPv4 routing
   infrastructure.  IPv6 nodes that use this technique are assigned
   special IPv6 unicast addresses that carry a global IPv4 address in
   the low-order 32 bits.  This type of address is termed an "IPv4-
   compatible IPv6 address" and has the format:

   |                80 bits               | 16 |      32 bits        |
   +--------------------------------------+--------------------------+
   |0000..............................0000|0000|    IPv4 address     |
   +--------------------------------------+----+---------------------+

   Note: The IPv4 address used in the "IPv4-compatible IPv6 address"
   must be a globally-unique IPv4 unicast address.

   A second type of IPv6 address which holds an embedded IPv4 address is
   also defined.  This address type is used to represent the addresses
   of IPv4 nodes as IPv6 addresses.  This type of address is termed an
   "IPv4-mapped IPv6 address" and has the format:



Hinden & Deering            Standards Track                    [Page 10]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   |                80 bits               | 16 |      32 bits        |
   +--------------------------------------+--------------------------+
   |0000..............................0000|FFFF|    IPv4 address     |
   +--------------------------------------+----+---------------------+


2.5.6 Local-Use IPv6 Unicast Addresses


   There are two types of local-use unicast addresses defined.  These
   are Link-Local and Site-Local.  The Link-Local is for use on a single
   link and the Site-Local is for use in a single site.  Link-Local
   addresses have the following format:

   |   10     |
   |  bits    |         54 bits         |          64 bits           |
   +----------+-------------------------+----------------------------+
   |1111111010|           0             |       interface ID         |
   +----------+-------------------------+----------------------------+

   Link-Local addresses are designed to be used for addressing on a
   single link for purposes such as automatic address configuration,
   neighbor discovery, or when no routers are present.

   Routers must not forward any packets with link-local source or
   destination addresses to other links.

   Site-Local addresses have the following format:

   |   10     |
   |  bits    |         54 bits         |         64 bits            |
   +----------+-------------------------+----------------------------+
   |1111111011|        subnet ID        |       interface ID         |
   +----------+-------------------------+----------------------------+

   Site-local addresses are designed to be used for addressing inside of
   a site without the need for a global prefix.  Although a subnet ID
   may be up to 54-bits long, it is expected that globally-connected
   sites will use the same subnet IDs for site-local and global
   prefixes.

   Routers must not forward any packets with site-local source or
   destination addresses outside of the site.

2.6 Anycast Addresses


   An IPv6 anycast address is an address that is assigned to more than
   one interface (typically belonging to different nodes), with the
   property that a packet sent to an anycast address is routed to the
   "nearest" interface having that address, according to the routing
   protocols' measure of distance.

   Anycast addresses are allocated from the unicast address space, using
   any of the defined unicast address formats.  Thus, anycast addresses
   are syntactically indistinguishable from unicast addresses.  When a
   unicast address is assigned to more than one interface, thus turning
   it into an anycast address, the nodes to which the address is
   assigned must be explicitly configured to know that it is an anycast
   address.

   For any assigned anycast address, there is a longest prefix P of that
   address that identifies the topological region in which all
   interfaces belonging to that anycast address reside.  Within the
   region identified by P, the anycast address must be maintained as a
   separate entry in the routing system (commonly referred to as a "host
   route"); outside the region identified by P, the anycast address may
   be aggregated into the routing entry for prefix P.

   Note that in the worst case, the prefix P of an anycast set may be
   the null prefix, i.e., the members of the set may have no topological
   locality.  In that case, the anycast address must be maintained as a
   separate routing entry throughout the entire internet, which presents
   a severe scaling limit on how many such "global" anycast sets may be
   supported.  Therefore, it is expected that support for global anycast
   sets may be unavailable or very restricted.

   One expected use of anycast addresses is to identify the set of
   routers belonging to an organization providing internet service.
   Such addresses could be used as intermediate addresses in an IPv6
   Routing header, to cause a packet to be delivered via a particular
   service provider or sequence of service providers.

   Some other possible uses are to identify the set of routers attached
   to a particular subnet, or the set of routers providing entry into a
   particular routing domain.

   There is little experience with widespread, arbitrary use of internet
   anycast addresses, and some known complications and hazards when
   using them in their full generality [ANYCST].  Until more experience
   has been gained and solutions are specified, the following
   restrictions are imposed on IPv6 anycast addresses:




Hinden & Deering            Standards Track                    [Page 12]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   o  An anycast address must not be used as the source address of an
      IPv6 packet.

   o  An anycast address must not be assigned to an IPv6 host, that is,
      it may be assigned to an IPv6 router only.


2.6.1 Required Anycast Address


   The Subnet-Router anycast address is predefined.  Its format is as
   follows:

   |                         n bits                 |   128-n bits   |
   +------------------------------------------------+----------------+
   |                   subnet prefix                | 00000000000000 |
   +------------------------------------------------+----------------+

   The "subnet prefix" in an anycast address is the prefix which
   identifies a specific link.  This anycast address is syntactically
   the same as a unicast address for an interface on the link with the
   interface identifier set to zero.

   Packets sent to the Subnet-Router anycast address will be delivered
   to one router on the subnet.  All routers are required to support the
   Subnet-Router anycast addresses for the subnets to which they have
   interfaces.

   The subnet-router anycast address is intended to be used for
   applications where a node needs to communicate with any one of the
   set of routers.


2.7 Multicast Addresses


   An IPv6 multicast address is an identifier for a group of interfaces
   (typically on different nodes).  An interface may belong to any
   number of multicast groups.  Multicast addresses have the following
   format:

   |   8    |  4 |  4 |                  112 bits                   |
   +------ -+----+----+---------------------------------------------+
   |11111111|flgs|scop|                  group ID                   |
   +--------+----+----+---------------------------------------------+

         binary 11111111 at the start of the address identifies the
         address as being a multicast address.

                                       +-+-+-+-+
         flgs is a set of 4 flags:     |0|0|0|T|
                                       +-+-+-+-+



Hinden & Deering            Standards Track                    [Page 13]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


            The high-order 3 flags are reserved, and must be initialized
            to 0.

            T = 0 indicates a permanently-assigned ("well-known")
            multicast address, assigned by the Internet Assigned Number
            Authority (IANA).

            T = 1 indicates a non-permanently-assigned ("transient")
            multicast address.

         scop is a 4-bit multicast scope value used to limit the scope
         of the multicast group.  The values are:

            0  reserved
            1  interface-local scope
            2  link-local scope
            3  reserved
            4  admin-local scope
            5  site-local scope
            6  (unassigned)
            7  (unassigned)
            8  organization-local scope
            9  (unassigned)
            A  (unassigned)
            B  (unassigned)
            C  (unassigned)
            D  (unassigned)
            E  global scope
            F  reserved

            interface-local scope spans only a single interface on a
            node, and is useful only for loopback transmission of
            multicast.

            link-local and site-local multicast scopes span the same
            topological regions as the corresponding unicast scopes.

            admin-local scope is the smallest scope that must be
            administratively configured, i.e., not automatically derived
            from physical connectivity or other, non- multicast-related
            configuration.

            organization-local scope is intended to span multiple sites
            belonging to a single organization.

            scopes labeled "(unassigned)" are available for
            administrators to define additional multicast regions.




Hinden & Deering            Standards Track                    [Page 14]

         group ID identifies the multicast group, either permanent or
         transient, within the given scope.

   The "meaning" of a permanently-assigned multicast address is
   independent of the scope value.  For example, if the "NTP servers
   group" is assigned a permanent multicast address with a group ID of
   101 (hex), then:

      FF01:0:0:0:0:0:0:101 means all NTP servers on the same interface
      (i.e., the same node) as the sender.

      FF02:0:0:0:0:0:0:101 means all NTP servers on the same link as the
      sender.

      FF05:0:0:0:0:0:0:101 means all NTP servers in the same site as the
      sender.

      FF0E:0:0:0:0:0:0:101 means all NTP servers in the internet.

   Non-permanently-assigned multicast addresses are meaningful only
   within a given scope.  For example, a group identified by the non-
   permanent, site-local multicast address FF15:0:0:0:0:0:0:101 at one
   site bears no relationship to a group using the same address at a
   different site, nor to a non-permanent group using the same group ID
   with different scope, nor to a permanent group with the same group
   ID.

   Multicast addresses must not be used as source addresses in IPv6
   packets or appear in any Routing header.

   Routers must not forward any multicast packets beyond of the scope
   indicated by the scop field in the destination multicast address.

   Nodes must not originate a packet to a multicast address whose scop
   field contains the reserved value 0; if such a packet is received, it
   must be silently dropped.  Nodes should not originate a packet to a
   multicast address whose scop field contains the reserved value F; if
   such a packet is sent or received, it must be treated the same as
   packets destined to a global (scop E) multicast address.


2.7.1 Pre-Defined Multicast Addresses


   The following well-known multicast addresses are pre-defined.  The
   group ID's defined in this section are defined for explicit scope
   values.

   Use of these group IDs for any other scope values, with the T flag
   equal to 0, is not allowed.

                                      FF0F:0:0:0:0:0:0:0

   The above multicast addresses are reserved and shall never be
   assigned to any multicast group.

      All Nodes Addresses:    FF01:0:0:0:0:0:0:1
                              FF02:0:0:0:0:0:0:1

   The above multicast addresses identify the group of all IPv6 nodes,
   within scope 1 (interface-local) or 2 (link-local).

      All Routers Addresses:   FF01:0:0:0:0:0:0:2
                               FF02:0:0:0:0:0:0:2
                               FF05:0:0:0:0:0:0:2

   The above multicast addresses identify the group of all IPv6 routers,
   within scope 1 (interface-local), 2 (link-local), or 5 (site-local).

      Solicited-Node Address:  FF02:0:0:0:0:1:FFXX:XXXX

   Solicited-node multicast address are computed as a function of a
   node's unicast and anycast addresses.  A solicited-node multicast
   address is formed by taking the low-order 24 bits of an address
   (unicast or anycast) and appending those bits to the prefix
   FF02:0:0:0:0:1:FF00::/104 resulting in a multicast address in the
   range

      FF02:0:0:0:0:1:FF00:0000

   to

      FF02:0:0:0:0:1:FFFF:FFFF




Hinden & Deering            Standards Track                    [Page 16]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   For example, the solicited node multicast address corresponding to
   the IPv6 address 4037::01:800:200E:8C6C is FF02::1:FF0E:8C6C.  IPv6
   addresses that differ only in the high-order bits, e.g., due to
   multiple high-order prefixes associated with different aggregations,
   will map to the same solicited-node address thereby, reducing the
   number of multicast addresses a node must join.

   A node is required to compute and join (on the appropriate interface)
   the associated Solicited-Node multicast addresses for every unicast
   and anycast address it is assigned.


2.8 A Node's Required Addresses


   A host is required to recognize the following addresses as
   identifying itself:

      o  Its required Link-Local Address for each interface.
      o  Any additional Unicast and Anycast Addresses that have been
         configured for the node's interfaces (manually or
         automatically).
      o  The loopback address.
      o  The All-Nodes Multicast Addresses defined in section 2.7.1.
      o  The Solicited-Node Multicast Address for each of its unicast
         and anycast addresses.
      o  Multicast Addresses of all other groups to which the node
         belongs.

   A router is required to recognize all addresses that a host is
   required to recognize, plus the following addresses as identifying
   itself:

      o  The Subnet-Router Anycast Addresses for all interfaces for
         which it is configured to act as a router.
      o  All other Anycast Addresses with which the router has been
         configured.
      o  The All-Routers Multicast Addresses defined in section 2.7.1.


3. Security Considerations


   IPv6 addressing documents do not have any direct impact on Internet
   infrastructure security.  Authentication of IPv6 packets is defined
   in [AUTH].

   Notes:

   1. The "unspecified address", the "loopback address", and the IPv6
      Addresses with Embedded IPv4 Addresses are assigned out of the
      0000 0000 binary prefix space.

   2. For now, IANA should limit its allocation of IPv6 unicast address
      space to the range of addresses that start with binary value 001.
      The rest of the global unicast address space (approximately 85% of
      the IPv6 address space) is reserved for future definition and use,
      and is not to be assigned by IANA at this time.

APPENDIX A: Creating Modified EUI-64 format Interface Identifiers

   Depending on the characteristics of a specific link or node there are
   a number of approaches for creating Modified EUI-64 format interface
   identifiers.  This appendix describes some of these approaches.

Links or Nodes with IEEE EUI-64 Identifiers

   The only change needed to transform an IEEE EUI-64 identifier to an
   interface identifier is to invert the "u" (universal/local) bit.  For
   example, a globally unique IEEE EUI-64 identifier of the form:

   |0              1|1              3|3              4|4              6|
   |0              5|6              1|2              7|8              3|
   +----------------+----------------+----------------+----------------+
   |cccccc0gcccccccc|ccccccccmmmmmmmm|mmmmmmmmmmmmmmmm|mmmmmmmmmmmmmmmm|
   +----------------+----------------+----------------+----------------+

   where "c" are the bits of the assigned company_id, "0" is the value
   of the universal/local bit to indicate global scope, "g" is
   individual/group bit, and "m" are the bits of the manufacturer-
   selected extension identifier.  The IPv6 interface identifier would
   be of the form:

   |0              1|1              3|3              4|4              6|
   |0              5|6              1|2              7|8              3|
   +----------------+----------------+----------------+----------------+
   |cccccc1gcccccccc|ccccccccmmmmmmmm|mmmmmmmmmmmmmmmm|mmmmmmmmmmmmmmmm|
   +----------------+----------------+----------------+----------------+

   The only change is inverting the value of the universal/local bit.

Links or Nodes with IEEE 802 48 bit MAC's

   [EUI64] defines a method to create a IEEE EUI-64 identifier from an
   IEEE 48bit MAC identifier.  This is to insert two octets, with
   hexadecimal values of 0xFF and 0xFE, in the middle of the 48 bit MAC
   (between the company_id and vendor supplied id).  For example, the 48
   bit IEEE MAC with global scope:

   |0              1|1              3|3              4|
   |0              5|6              1|2              7|
   +----------------+----------------+----------------+
   |cccccc0gcccccccc|ccccccccmmmmmmmm|mmmmmmmmmmmmmmmm|
   +----------------+----------------+----------------+

   where "c" are the bits of the assigned company_id, "0" is the value
   of the universal/local bit to indicate global scope, "g" is
   individual/group bit, and "m" are the bits of the manufacturer-
   selected extension identifier.  The interface identifier would be of
   the form:

   |0              1|1              3|3              4|4              6|
   |0              5|6              1|2              7|8              3|

   |cccccc1gcccccccc|cccccccc11111111|11111110mmmmmmmm|mmmmmmmmmmmmmmmm|
   +----------------+----------------+----------------+----------------+

   When IEEE 802 48bit MAC addresses are available (on an interface or a
   node), an implementation may use them to create interface identifiers
   due to their availability and uniqueness properties.

Links with Other Kinds of Identifiers

   There are a number of types of links that have link-layer interface
   identifiers other than IEEE EIU-64 or IEEE 802 48-bit MACs.  Examples
   include LocalTalk and Arcnet.  The method to create an Modified EUI-
   64 format identifier is to take the link identifier (e.g., the
   LocalTalk 8 bit node identifier) and zero fill it to the left.  For
   example, a LocalTalk 8 bit node identifier of hexadecimal value 0x4F
   results in the following interface identifier:

   |0              1|1              3|3              4|4              6|
   |0              5|6              1|2              7|8              3|
   +----------------+----------------+----------------+----------------+
   |0000000000000000|0000000000000000|0000000000000000|0000000001001111|
   +----------------+----------------+----------------+----------------+

   Note that this results in the universal/local bit set to "0" to
   indicate local scope.

Links without Identifiers

   There are a number of links that do not have any type of built-in
   identifier.  The most common of these are serial links and configured
   tunnels.  Interface identifiers must be chosen that are unique within
   a subnet-prefix.




Hinden & Deering            Standards Track                    [Page 22]
 
RFC 3513              IPv6 Addressing Architecture            April 2003


   When no built-in identifier is available on a link the preferred
   approach is to use a global interface identifier from another
   interface or one which is assigned to the node itself.  When using
   this approach no other interface connecting the same node to the same
   subnet-prefix may use the same identifier.

   If there is no global interface identifier available for use on the
   link the implementation needs to create a local-scope interface
   identifier.  The only requirement is that it be unique within a
   subnet prefix.  There are many possible approaches to select a
   subnet-prefix-unique interface identifier.  These include:

      Manual Configuration
      Node Serial Number
      Other node-specific token

   The subnet-prefix-unique interface identifier should be generated in
   a manner that it does not change after a reboot of a node or if
   interfaces are added or deleted from the node.

   The selection of the appropriate algorithm is link and implementation
   dependent.  The details on forming interface identifiers are defined
   in the appropriate "IPv6 over <link>" specification.  It is strongly
   recommended that a collision detection algorithm be implemented as
   part of any automatic algorithm.

APPENDIX B: Changes from RFC-2373

   The following changes were made from RFC-2373 "IP Version 6
   Addressing Architecture":

   -  Clarified text in section 2.2 to allow "::" to represent one or
      more groups of 16 bits of zeros.
   -  Changed uniqueness requirement of Interface Identifiers from
      unique on a link to unique within a subnet prefix.  Also added a
      recommendation that the same interface identifier not be assigned
      to different machines on a link.
   -  Change site-local format to make the subnet ID field 54-bit long
      and remove the 38-bit zero's field.
   -  Added description of multicast scop values and rules to handle the
      reserved scop value 0.
   -  Revised sections 2.4 and 2.5.6 to simplify and clarify how
      different address types  are identified.  This was done to insure
      that implementations do not build in any knowledge about global
      unicast format prefixes.  Changes include:
         o  Removed Format Prefix (FP) terminology
         o  Revised list of address types to only include exceptions to
            global unicast and a singe entry that identifies everything
            else as Global Unicast.
         o  Removed list of defined prefix exceptions from section 2.5.6
            as it is now the main part of section 2.4.
   -  Clarified text relating to EUI-64 identifiers to distinguish
      between IPv6's "Modified EUI-64 format" identifiers and IEEE EUI-
      64 identifiers.
   -  Combined the sections on the Global Unicast Addresses and NSAP
      Addresses into a single section on Global Unicast Addresses,
      generalized the Global Unicast format, and cited [AGGR] and [NSAP]
      as examples.
   -  Reordered sections 2.5.4 and 2.5.5.
   -  Removed section 2.7.2 Assignment of New IPv6 Multicast Addresses
      because this is being redefined elsewhere.
   -  Added an IANA considerations section that updates the IANA IPv6
      address allocations and documents the NSAP and AGGR allocations.
   -  Added clarification that the "IPv4-compatible IPv6 address" must
      use global IPv4 unicast addresses.
   -  Divided references in to normative and non-normative sections.
   -  Added reference to [PRIV] in section 2.5.1
   -  Added clarification that routers must not forward multicast
      packets outside of the scope indicated in the multicast address.
   -  Added clarification that routers must not forward packets with
       source address of the unspecified address.
   -  Added clarification that routers must drop packets received on an
      interface with destination address of loopback.
   -  Clarified the definition of IPv4-mapped addresses.

RFC 3513              IPv6 Addressing Architecture            April 2003


   -  Removed the ABNF Description of Text Representations Appendix.
   -  Removed the address block reserved for IPX addresses.
   -  Multicast scope changes:
         o  Changed name of scope value 1 from "node-local" to
            "interface-local"
         o  Defined scope value 4 as "admin-local"
   -  Corrected reference to RFC1933 and updated references.
   -  Many small changes to clarify and make the text more consistent.

Abstract

   The Hypertext Markup Language (HTML) is a simple markup language used
   to create hypertext documents that are platform independent. HTML
   documents are SGML documents with generic semantics that are
   appropriate for representing information from a wide range of
   domains. HTML markup can represent hypertext news, mail,
   documentation, and hypermedia; menus of options; database query
   results; simple structured documents with in-lined graphics; and
   hypertext views of existing bodies of information.

   HTML has been in use by the World Wide Web (WWW) global information
   initiative since 1990. This specification roughly corresponds to the
   capabilities of HTML in common use prior to June 1994. HTML is an
   application of ISO Standard 8879:1986 Information Processing Text and
   Office Systems; Standard Generalized Markup Language (SGML).

   The "text/html" Internet Media Type (RFC 1590) and MIME Content Type
   (RFC 1521) is defined by this specification.

1. Introduction

   The HyperText Markup Language (HTML) is a simple data format used to
   create hypertext documents that are portable from one platform to
   another. HTML documents are SGML documents with generic semantics
   that are appropriate for representing information from a wide range
   of domains.




Berners-Lee & Connolly      Standards Track                     [Page 2]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   As HTML is an application of SGML, this specification assumes a
   working knowledge of [SGML].

1.1. Scope

   HTML has been in use by the World-Wide Web (WWW) global information
   initiative since 1990. Previously, informal documentation on HTML has
   been available from a number of sources on the Internet. This
   specification brings together, clarifies, and formalizes a set of
   features that roughly corresponds to the capabilities of HTML in
   common use prior to June 1994. A number of new features to HTML are
   being proposed and experimented in the Internet community.

   This document thus defines a HTML 2.0 (to distinguish it from the
   previous informal specifications). Future (generally upwardly
   compatible) versions of HTML with new features will be released with
   higher version numbers.

   HTML is an application of ISO Standard 8879:1986, "Information
   Processing Text and Office Systems; Standard Generalized Markup
   Language" (SGML). The HTML Document Type Definition (DTD) is a formal
   definition of the HTML syntax in terms of SGML.

   This specification also defines HTML as an Internet Media
   Type[IMEDIA] and MIME Content Type[MIME] called `text/html'. As such,
   it defines the semantics of the HTML syntax and how that syntax
   should be interpreted by user agents.

1.2. Conformance

   This specification governs the syntax of HTML documents and aspects
   of the behavior of HTML user agents.

1.2.1. Documents

   A document is a conforming HTML document if:

        * It is a conforming SGML document, and it conforms to the
        HTML DTD (see 9.1, "HTML DTD").

            NOTE - There are a number of syntactic idioms that
            are not supported or are supported inconsistently in
            some historical user agent implementations. These
            idioms are identified in notes like this throughout
            this specification.

        * It conforms to the application conventions in this
        specification. For example, the value of the HREF attribute



Berners-Lee & Connolly      Standards Track                     [Page 3]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


        of the <A> element must conform to the URI syntax.

        * Its document character set includes [ISO-8859-1] and
        agrees with [ISO-10646]; that is, each code position listed
        in 13, "The HTML Coded Character Set" is included, and each
        code position in the document character set is mapped to the
        same character as [ISO-10646] designates for that code
        position.

            NOTE - The document character set is somewhat
            independent of the character encoding scheme used to
            represent a document. For example, the `ISO-2022-JP'
            character encoding scheme can be used for HTML
            documents, since its repertoire is a subset of the
            [ISO-10646] repertoire. The critical distinction is
            that numeric character references agree with
            [ISO-10646] regardless of how the document is
            encoded.

1.2.2. Feature Test Entities

   The HTML DTD defines a standard HTML document type and several
   variations, by way of feature test entities. Feature test entities
   are declarations in the HTML DTD that control the inclusion or
   exclusion of portions of the DTD.

    HTML.Recommended
            Certain features of the language are necessary for
            compatibility with widespread usage, but they may
            compromise the structural integrity of a document. This
            feature test entity selects a more prescriptive document
            type definition that eliminates those features. It is
            set to `IGNORE' by default.

            For example, in order to preserve the structure of a
            document, an editing user agent may translate HTML
            documents to the recommended subset, or it may require
            that the documents be in the recommended subset for
            import.

    HTML.Deprecated
            Certain features of the language are necessary for
            compatibility with earlier versions of the
            specification, but they tend to be used and implemented
            inconsistently, and their use is deprecated. This
            feature test entity enables a document type definition
            that allows these features. It is set to `INCLUDE' by
            default.



Berners-Lee & Connolly      Standards Track                     [Page 4]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


            Documents generated by translation software or editing
            software should not contain deprecated idioms.

1.2.3. User Agents

   An HTML user agent conforms to this specification if:

        * It parses the characters of an HTML document into data
        characters and markup according to [SGML].

            NOTE - In the interest of robustness and
            extensibility, there are a number of widely deployed
            conventions for handling non-conforming documents.
            See 4.2.1, "Undeclared Markup Error Handling" for
            details.

        * It supports the `ISO-8859-1' character encoding scheme and
        processes each character in the ISO Latin Alphabet No. 1 as
        specified in 6.1, "The HTML Document Character Set".

            NOTE - To support non-western writing systems, HTML
            user agents are encouraged to support
            `ISO-10646-UCS-2' or similar character encoding
            schemes and as much of the character repertoire of
            [ISO-10646] as is practical.

        * It behaves identically for documents whose parsed token
        sequences are identical.

        For example, comments and the whitespace in tags disappear
        during tokenization, and hence they do not influence the
        behavior of conforming user agents.

2. Terms

    absolute URI
            a URI in absolute form; for example, as per [URL]

    anchor
            one of two ends of a hyperlink; typically, a phrase
            marked as an <A> element.

    base URI
            an absolute URI used in combination with a relative URI
            to determine another absolute URI.

    character
            An atom of information, for example a letter or a digit.
            Graphic characters have associated glyphs, whereas
            control characters have associated processing semantics.

    character encoding
    scheme
            A function whose domain is the set of sequences of
            octets, and whose range is the set of sequences of
            characters from a character repertoire; that is, a
            sequence of octets and a character encoding scheme
            determines a sequence of characters.

    character repertoire
            A finite set of characters; e.g. the range of a coded
            character set.

    code position
            An integer. A coded character set and a code position
            from its domain determine a character.

    coded character set
            A function whose domain is a subset of the integers and
            whose range is a character repertoire. That is, for some
            set of integers (usually of the form {0, 1, 2, ..., N}
            ), a coded character set and an integer in that set
            determine a character. Conversely, a character and a
            coded character set determine the character's code
            position (or, in rare cases, a few code positions).

    conforming HTML user
    agent
            A user agent that conforms to this specification in its
            processing of the Internet Media Type `text/html'.

    data character
            Characters other than markup, which make up the content
            of elements.

    document character set
            a coded character set whose range includes all
            characters used in a document. Every SGML document has
            exactly one document character set. Numeric character
            references are resolved via the document character set.

    DTD
            document type definition. Rules that apply SGML to the
            markup of documents of a particular type, including a
            set of element and entity declarations. [SGML]

    element
            A component of the hierarchical structure defined by a
            document type definition; it is identified in a document
            instance by descriptive markup, usually a start-tag and
            end-tag. [SGML]

    end-tag
            Descriptive markup that identifies the end of an
            element. [SGML]

    entity
            data with an associated notation or interpretation; for
            example, a sequence of octets associated with an
            Internet Media Type. [SGML]

    fragment identifier
            the portion of an HREF attribute value following the `#'
            character which modifies the presentation of the
            destination of a hyperlink.

    form data set
            a sequence of name/value pairs; the names are given by
            an HTML document and the values are given by a user.

    HTML document
            An SGML document conforming to this document type
            definition.

    hyperlink
            a relationship between two anchors, called the head and
            the tail. The link goes from the tail to the head. The
            head and tail are also known as destination and source,
            respectively.

    markup
            Syntactically delimited characters added to the data of
            a document to represent its structure. There are four
            different kinds of markup: descriptive markup (tags),
            references, markup declarations, and processing
            instructions. [SGML]

    may
            A document or user interface is conforming whether this
            statement applies or not.

    media type
            an Internet Media Type, as per [IMEDIA].

    message entity
            a head and body. The head is a collection of name/value
            fields, and the body is a sequence of octets. The head
            defines the content type and content transfer encoding
            of the body. [MIME]

    minimally conforming
    HTML user agent
            A user agent that conforms to this specification except
            for form processing. It may only process level 1 HTML
            documents.

    must
            Documents or user agents in conflict with this statement
            are not conforming.

    numeric character
    reference
            markup that refers to a character by its code position
            in the document character set.

    SGML document
            A sequence of characters organized physically as a set
            of entities and logically into a hierarchy of elements.
            An SGML document consists of data characters and markup;
            the markup describes the structure of the information
            and an instance of that structure. [SGML]

    shall
            If a document or user agent conflicts with this
            statement, it does not conform to this specification.

    should
            If a document or user agent conflicts with this
            statement, undesirable results may occur in practice
            even though it conforms to this specification.

    start-tag
            Descriptive markup that identifies the start of an
            element and specifies its generic identifier and
            attributes. [SGML]

    syntax-reference
    character set
            A coded character set whose range includes all
            characters used for markup; e.g. name characters and
            delimiter characters.

    tag
            Markup that delimits an element. A tag includes a name
            which refers to an element declaration in the DTD, and
            may include attributes. [SGML]

    text entity
            A finite sequence of characters. A text entity typically
            takes the form of a sequence of octets with some
            associated character encoding scheme, transmitted over
            the network or stored in a file. [SGML]

    typical
            Typical processing is described for many elements. This
            is not a mandatory part of the specification but is
            given as guidance for designers and to help explain the
            uses for which the elements were intended.

    URI
            A Uniform Resource Identifier is a formatted string that
            serves as an identifier for a resource, typically on the
            Internet. URIs are used in HTML to identify the anchors
            of hyperlinks. URIs in common practice include Uniform
            Resource Locators (URLs)[URL] and Relative URLs
            [RELURL].

    user agent
            A component of a distributed system that presents an
            interface and processes requests on behalf of a user;
            for example, a www browser or a mail user agent.

3. HTML as an Application of SGML

   HTML is an application of ISO 8879:1986 -- Standard Generalized
   Markup Language (SGML). SGML is a system for defining structured
   document types and markup languages to represent instances of those
   document types[SGML]. The public text -- DTD and SGML declaration --
   of the HTML document type definition are provided in 9, "HTML Public
   Text".

   The term "HTML" refers to both the document type defined here and the
   markup language for representing instances of this document type.

3.1. SGML Documents

   An HTML document is an SGML document; that is, a sequence of
   characters organized physically into a set of entities, and logically
   as a hierarchy of elements.

   In the SGML specification, the first production of the SGML syntax
   grammar separates an SGML document into three parts: an SGML
   declaration, a prologue, and an instance. For the purposes of this
   specification, the prologue is a DTD. This DTD describes another
   grammar: the start symbol is given in the doctype declaration, the
   terminals are data characters and tags, and the productions are
   determined by the element declarations. The instance must conform to
   the DTD, that is, it must be in the language defined by this grammar.

   The SGML declaration determines the lexicon of the grammar. It
   specifies the document character set, which determines a character
   repertoire that contains all characters that occur in all text
   entities in the document, and the code positions associated with
   those characters.

   The SGML declaration also specifies the syntax-reference character
   set of the document, and a few other parameters that bind the
   abstract syntax of SGML to a concrete syntax. This concrete syntax
   determines how the sequence of characters of the document is mapped
   to a sequence of terminals in the grammar of the prologue.








Berners-Lee & Connolly      Standards Track                    [Page 10]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   For example, consider the following document:

    <!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN">
    <title>Parsing Example</title>
    <p>Some text. <em>&#42;wow&#42;</em></p>

   An HTML user agent should use the SGML declaration that is given in
   9.5, "SGML Declaration for HTML". According to its document character
   set, `&#42;' refers to an asterisk character, `*'.

   The instance above is regarded as the following sequence of
   terminals:

        1. start-tag: TITLE

        2. data characters: "Parsing Example"

        3. end-tag: TITLE

        4. start-tag: P

        5. data characters "Some text."

        6. start-tag: EM

        7. data characters: "*wow*"

        8. end-tag: EM

        9. end-tag: P





















Berners-Lee & Connolly      Standards Track                    [Page 11]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   The start symbol of the DTD grammar is HTML, and the productions are
   given in the public text identified by `-//IETF//DTD HTML 2.0//EN'
   (9.1, "HTML DTD"). The terminals above parse as:

       HTML
        |
        \-HEAD
        |  |
        |  \-TITLE
        |      |
        |      \-<TITLE>
        |      |
        |      \-"Parsing Example"
        |      |
        |      \-</TITLE>
        |
        \-BODY
          |
          \-P
            |
            \-<P>
            |
            \-"Some text. "
            |
            \-EM
            |  |
            |  \-<EM>
            |  |
            |  \-"*wow*"
            |  |
            |  \-</EM>
            |
            \-</P>

   Some of the elements are delimited explicitly by tags, while the
   boundaries of others are inferred. The <HTML> element contains a
   <HEAD> element and a <BODY> element. The <HEAD> contains <TITLE>,
   which is explicitly delimited by start- and end-tags.

3.2. HTML Lexical Syntax

   SGML specifies an abstract syntax and a reference concrete syntax.
   Aside from certain quantities and capacities (e.g. the limit on the
   length of a name), all HTML documents use the reference concrete
   syntax. In particular, all markup characters are in the repertoire of
   [ISO-646]. Data characters are drawn from the document character set
   (see 6, "Characters, Words, and Paragraphs").




Berners-Lee & Connolly      Standards Track                    [Page 12]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   A complete discussion of SGML parsing, e.g. the mapping of a sequence
   of characters to a sequence of tags and data, is left to the SGML
   standard[SGML]. This section is only a summary.

3.2.1. Data Characters

   Any sequence of characters that do not constitute markup (see 9.6
   "Delimiter Recognition" of [SGML]) are mapped directly to strings of
   data characters. Some markup also maps to data character strings.
   Numeric character references map to single-character strings, via the
   document character set. Each reference to one of the general entities
   defined in the HTML DTD maps to a single-character string.

   For example,

    abc&lt;def    => "abc","<","def"
    abc&#60;def   => "abc","<","def"

   The terminating semicolon on entity or numeric character references
   is only necessary when the character following the reference would
   otherwise be recognized as part of the name (see 9.4.5 "Reference
   End" in [SGML]).

    abc &lt def     => "abc ","<"," def"
    abc &#60 def    => "abc ","<"," def"

   An ampersand is only recognized as markup when it is followed by a
   letter or a `#' and a digit:

    abc & lt def    => "abc & lt def"
    abc &# 60 def    => "abc &# 60 def"

   A useful technique for translating plain text to HTML is to replace
   each '<', '&', and '>' by an entity reference or numeric character
   reference as follows:

                     ENTITY      NUMERIC
           CHARACTER REFERENCE   CHAR REF     CHARACTER DESCRIPTION
           --------- ----------  -----------  ---------------------
             &       &amp;       &#38;        Ampersand
             <       &lt;        &#60;        Less than
             >       &gt;        &#62;        Greater than

        NOTE - There are SGML mechanisms, CDATA and RCDATA
        declared content, that allow most `<', `>', and `&'
        characters to be entered without the use of entity
        references. Because these mechanisms tend to be used and
        implemented inconsistently, and because they conflict



Berners-Lee & Connolly      Standards Track                    [Page 13]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


        with techniques for reducing HTML to 7 bit ASCII for
        transport, they are deprecated in this version of HTML.
        See 5.5.2.1, "Example and Listing: XMP, LISTING".

3.2.2. Tags

   Tags delimit elements such as headings, paragraphs, lists, character
   highlighting, and links. Most HTML elements are identified in a
   document as a start-tag, which gives the element name and attributes,
   followed by the content, followed by the end tag. Start-tags are
   delimited by `<' and `>'; end tags are delimited by `</' and `>'. An
   example is:

   <H1>This is a Heading</H1>

   Some elements only have a start-tag without an end-tag. For example,
   to create a line break, use the `<BR>' tag.  Additionally, the end
   tags of some other elements, such as Paragraph (`</P>'), List Item
   (`</LI>'), Definition Term (`</DT>'), and Definition Description
   (`</DD>') elements, may be omitted.

   The content of an element is a sequence of data character strings and
   nested elements. Some elements, such as anchors, cannot be nested.
   Anchors and character highlighting may be put inside other
   constructs. See the HTML DTD, 9.1, "HTML DTD" for full details.

      NOTE - The SGML declaration for HTML specifies SHORTTAG YES, which
      means that there are other valid syntaxes for tags, such as NET
      tags, `<EM/.../'; empty start tags, `<>'; and empty end-tags,
      `</>'. Until support for these idioms is widely deployed, their
      use is strongly discouraged.

3.2.3. Names

   A name consists of a letter followed by letters, digits, periods, or
   hyphens. The length of a name is limited to 72 characters by the
   `NAMELEN' parameter in the SGML declaration for HTML, 9.5, "SGML
   Declaration for HTML". Element and attribute names are not case
   sensitive, but entity names are.  For example, `<BLOCKQUOTE>',
   `<BlockQuote>', and `<blockquote>' are equivalent, whereas `&amp;' is
   different from `&AMP;'.

   In a start-tag, the element name must immediately follow the tag open
   delimiter `<'.







Berners-Lee & Connolly      Standards Track                    [Page 14]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


3.2.4. Attributes

   In a start-tag, white space and attributes are allowed between the
   element name and the closing delimiter. An attribute specification
   typically consists of an attribute name, an equal sign, and a value,
   though some attribute specifications may be just a name token. White
   space is allowed around the equal sign.

   The value of the attribute may be either:

        * A string literal, delimited by single quotes or double
        quotes and not containing any occurrences of the delimiting
        character.

            NOTE - Some historical implementations consider any
            occurrence of the `>' character to signal the end of
            a tag. For compatibility with such implementations,
            when `>' appears in an attribute value, it should be
            represented with a numeric character reference. For
            example, `<IMG SRC="eq1.jpg" alt="a>b">' should be
            written `<IMG SRC="eq1.jpg" alt="a&#62;b">' or `<IMG
            SRC="eq1.jpg" alt="a&gt;b">'.

        * A name token (a sequence of letters, digits, periods, or
        hyphens). Name tokens are not case sensitive.

            NOTE - Some historical implementations allow any
            character except space or `>' in a name token.

   In this example, <img> is the element name, src is the attribute
   name, and `http://host/dir/file.gif' is the attribute value:

   <img src='http://host/dir/file.gif'>

   A useful technique for computing an attribute value literal for a
   given string is to replace each quote and white space character by an
   entity reference or numeric character reference as follows:

                     ENTITY      NUMERIC
           CHARACTER REFERENCE   CHAR REF     CHARACTER DESCRIPTION
           --------- ----------  -----------  ---------------------
             HT                  &#9;         Tab
             LF                  &#10;        Line Feed
             CR                  &#13;        Carriage Return
             SP                  &#32;        Space
             "       &quot;      &#34;        Quotation mark
             &       &amp;       &#38;        Ampersand




Berners-Lee & Connolly      Standards Track                    [Page 15]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   For example:

   <IMG SRC="image.jpg" alt="First &quot;real&quot; example">

   The `NAMELEN' parameter in the SGML declaration (9.5, "SGML
   Declaration for HTML") limits the length of an attribute value to
   1024 characters.

   Attributes such as ISMAP and COMPACT may be written using a minimized
   syntax (see 7.9.1.2 "Omitted Attribute Name" in [SGML]). The markup:

   <UL COMPACT="compact">

   can be written using a minimized syntax:

   <UL COMPACT>

   NOTE - Some historical implementations only understand the minimized
   syntax.

3.2.5. Comments

   To include comments in an HTML document, use a comment declaration. A
   comment declaration consists of `<!' followed by zero or more
   comments followed by `>'. Each comment starts with `--' and includes
   all text up to and including the next occurrence of `--'. In a
   comment declaration, white space is allowed after each comment, but
   not before the first comment.  The entire comment declaration is
   ignored.

      NOTE - Some historical HTML implementations incorrectly consider
      any `>' character to be the termination of a comment.

   For example:

    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
    <HEAD>
    <TITLE>HTML Comment Example</TITLE>
    <!-- Id: html-sgml.sgm,v 1.5 1995/05/26 21:29:50 connolly Exp  -->
    <!-- another -- -- comment -->
    <!>
    </HEAD>
    <BODY>

3.3. HTML Public Text Identifiers

   To identify information as an HTML document conforming to this
   specification, each document must start with one of the following
   document type declarations.

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

   This document type declaration refers to the HTML DTD in 9.1, "HTML
   DTD".

      NOTE - If the body of a `text/html' message entity does not begin
      with a document type declaration, an HTML user agent should infer
      the above document type declaration.

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Level 2//EN">

   This document type declaration also refers to the HTML DTD which
   appears in 9.1, "HTML DTD".

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Level 1//EN">

   This document type declaration refers to the level 1 HTML DTD in 9.3,
   "Level 1 HTML DTD". Form elements must not occur in level 1
   documents.

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict//EN">
   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0 Strict Level 1//EN">

   These two document type declarations refer to the HTML DTD in 9.2,
   "Strict HTML DTD" and 9.4, "Strict Level 1 HTML DTD". They refer to
   the more structurally rigid definition of HTML.

   HTML user agents may support other document types. In particular,
   they may support other formal public identifiers, or other document
   types altogether. They may support an internal declaration subset
   with supplemental entity, element, and other markup declarations.

3.4. Example HTML Document

    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
    <HTML>
    <!-- Here's a good place to put a comment. -->
    <HEAD>
    <TITLE>Structural Example</TITLE>
    </HEAD><BODY>
    <H1>First Header</H1>
    <P>This is a paragraph in the example HTML file. Keep in mind

    that the title does not appear in the document text, but that
    the header (defined by H1) does.</P>
    <OL>
    <LI>First item in an ordered list.
    <LI>Second item in an ordered list.

      <LI> Whitespace may be used to assist in reading the
           HTML source.
      </UL>
    <LI>Third item in an ordered list.
    </OL>
    <P>This is an additional paragraph. Technically, end tags are
    not required for paragraphs, although they are allowed. You can
    include character highlighting in a paragraph. <EM>This sentence
    of the paragraph is emphasized.</EM> Note that the &lt;/P&gt;
    end tag has been omitted.
    <P>
    <IMG SRC ="triangle.xbm" alt="Warning: ">
    Be sure to read these <b>bold instructions</b>.
    </BODY></HTML>

4. HTML as an Internet Media Type

   An HTML user agent allows users to interact with resources which have
   HTML representations. At a minimum, it must allow users to examine
   and navigate the content of HTML level 1 documents. HTML user agents
   should be able to preserve all formatting distinctions represented in
   an HTML document, and be able to simultaneously present resources
   referred to by IMG elements (they may ignore some formatting
   distinctions or IMG resources at the request of the user). Level 2
   HTML user agents should support form entry and submission.

4.1. text/html media type

   This specification defines the Internet Media Type [IMEDIA] (formerly
   referred to as the Content Type [MIME]) called `text/html'. The
   following is to be registered with [IANA].

    Media Type name
            text

    Media subtype name
            html

    Required parameters
            none




Berners-Lee & Connolly      Standards Track                    [Page 18]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    Optional parameters
            level, charset

    Encoding considerations
            any encoding is allowed

    Security considerations
            see 10, "Security Considerations"

    The optional parameters are defined as follows:

    Level
            The level parameter specifies the feature set used in
            the document. The level is an integer number, implying
            that any features of same or lower level may be present
            in the document. Level 1 is all features defined in this
            specification except those that require the <FORM>
            element. Level 2 includes form processing. Level 2 is
            the default.

    Charset
            The charset parameter (as defined in section 7.1.1 of
            RFC 1521[MIME]) may be given to specify the character
            encoding scheme used to represent the HTML document as a
            sequence of octets. The default value is outside the
            scope of this specification; but for example, the
            default is `US-ASCII' in the context of MIME mail, and
            `ISO-8859-1' in the context of HTTP [HTTP].

4.2. HTML Document Representation

   A message entity with a content type of `text/html' represents an
   HTML document, consisting of a single text entity. The `charset'
   parameter (whether implicit or explicit) identifies a character
   encoding scheme. The text entity consists of the characters
   determined by this character encoding scheme and the octets of the
   body of the message entity.

4.2.1. Undeclared Markup Error Handling

   To facilitate experimentation and interoperability between
   implementations of various versions of HTML, the installed base of
   HTML user agents supports a superset of the HTML 2.0 language by
   reducing it to HTML 2.0: markup in the form of a start-tag or end-
   tag, whose generic identifier is not declared is mapped to nothing
   during tokenization. Undeclared attributes are treated similarly. The
   entire attribute specification of an unknown attribute (i.e., the
   unknown attribute and its value, if any) should be ignored. On the



Berners-Lee & Connolly      Standards Track                    [Page 19]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   other hand, references to undeclared entities should be treated as
   data characters.

   For example:

    <div class=chapter><h1>foo</h1><p>...</div>
      => <H1>,"foo",</H1>,<P>,"..."
    xxx <P ID=z23> yyy
      => "xxx ",<P>," yyy
    Let &alpha; &amp; &beta; be finite sets.
      => "Let &alpha; & &beta; be finite sets."

   Support for notifying the user of such errors is encouraged.

   Information providers are warned that this convention is not binding:
   unspecified behavior may result, as such markup does not conform to
   this specification.

4.2.2. Conventional Representation of Newlines

   SGML specifies that a text entity is a sequence of records, each
   beginning with a record start character and ending with a record end
   character (code positions 10 and 13 respectively) (section 7.6.1,
   "Record Boundaries" in [SGML]).

   [MIME] specifies that a body of type `text/*' is a sequence of lines,
   each terminated by CRLF, that is, octets 13, 10.

   In practice, HTML documents are frequently represented and
   transmitted using an end of line convention that depends on the
   conventions of the source of the document; frequently, that
   representation consists of CR only, LF only, or a CR LF sequence.
   Hence the decoding of the octets will often result in a text entity
   with some missing record start and record end characters.

   Since there is no ambiguity, HTML user agents are encouraged to infer
   the missing record start and end characters.

   An HTML user agent should treat end of line in any of its variations
   as a word space in all contexts except preformatted text. Within
   preformatted text, an HTML user agent should treat any of the three
   common representations of end-of-line as starting a new line.

5. Document Structure

   An HTML document is a tree of elements, including a head and body,
   headings, paragraphs, lists, etc. Form elements are discussed in 8,
   "Forms".



Berners-Lee & Connolly      Standards Track                    [Page 20]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.1. Document Element: HTML

   The HTML document element consists of a head and a body, much like a
   memo or a mail message. The head contains the title and optional
   elements. The body is a text flow consisting of paragraphs, lists,
   and other elements.

5.2. Head: HEAD

   The head of an HTML document is an unordered collection of
   information about the document. For example:

    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
    <HEAD>
    <TITLE>Introduction to HTML</TITLE>
    </HEAD>
    ...

5.2.1. Title: TITLE

   Every HTML document must contain a <TITLE> element.

   The title should identify the contents of the document in a global
   context. A short title, such as "Introduction" may be meaningless out
   of context. A title such as "Introduction to HTML Elements" is more
   appropriate.

      NOTE - The length of a title is not limited; however, long titles
      may be truncated in some applications. To minimize this
      possibility, titles should be fewer than 64 characters.

   A user agent may display the title of a document in a history list or
   as a label for the window displaying the document. This differs from
   headings (5.4, "Headings: H1 ... H6"), which are typically displayed
   within the body text flow.

5.2.2. Base Address: BASE

   The optional <BASE> element provides a base address for interpreting
   relative URLs when the document is read out of context (see 7,
   "Hyperlinks"). The value of the HREF attribute must be an absolute
   URI.

5.2.3. Keyword Index: ISINDEX

   The <ISINDEX> element indicates that the user agent should allow the
   user to search an index by giving keywords. See 7.5, "Queries and
   Indexes" for details.



Berners-Lee & Connolly      Standards Track                    [Page 21]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.2.4. Link: LINK

   The <LINK> element represents a hyperlink (see 7, "Hyperlinks").  Any
   number of LINK elements may occur in the <HEAD> element of an HTML
   document. It has the same attributes as the <A> element (see 5.7.3,
   "Anchor: A").

   The <LINK> element is typically used to indicate authorship, related
   indexes and glossaries, older or more recent versions, document
   hierarchy, associated resources such as style sheets, etc.

5.2.5. Associated Meta-information: META

   The <META> element is an extensible container for use in identifying
   specialized document meta-information.  Meta-information has two main
   functions:

        * to provide a means to discover that the data set exists
        and how it might be obtained or accessed; and

        * to document the content, quality, and features of a data
        set, indicating its fitness for use.

   Each <META> element specifies a name/value pair. If multiple META
   elements are provided with the same name, their combined contents--
   concatenated as a comma-separated list--is the value associated with
   that name.

        NOTE - The <META> element should not be used where a
        specific element, such as <TITLE>, would be more
        appropriate. Rather than a <META> element with a URI as
        the value of the CONTENT attribute, use a <LINK>
        element.

   HTTP servers may read the content of the document <HEAD> to generate
   header fields corresponding to any elements defining a value for the
   attribute HTTP-EQUIV.

        NOTE - The method by which the server extracts document
        meta-information is unspecified and not mandatory. The
        <META> element only provides an extensible mechanism for
        identifying and embedding document meta-information --
        how it may be used is up to the individual server
        implementation and the HTML user agent.







Berners-Lee & Connolly      Standards Track                    [Page 22]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    Attributes of the META element:

    HTTP-EQUIV
            binds the element to an HTTP header field. An HTTP
            server may use this information to process the document.
            In particular, it may include a header field in the
            responses to requests for this document: the header name
            is taken from the HTTP-EQUIV attribute value, and the
            header value is taken from the value of the CONTENT
            attribute. HTTP header names are not case sensitive.

    NAME
            specifies the name of the name/value pair. If not
            present, HTTP-EQUIV gives the name.

    CONTENT
            specifies the value of the name/value pair.

    Examples

    If the document contains:

    <META HTTP-EQUIV="Expires"
          CONTENT="Tue, 04 Dec 1993 21:29:02 GMT">
    <meta http-equiv="Keywords" CONTENT="Fred">
    <META HTTP-EQUIV="Reply-to"
          content="fielding@ics.uci.edu (Roy Fielding)">
    <Meta Http-equiv="Keywords" CONTENT="Barney">

    then the server may include the following header fields:

    Expires: Tue, 04 Dec 1993 21:29:02 GMT
    Keywords: Fred, Barney
    Reply-to: fielding@ics.uci.edu (Roy Fielding)

    as part of the HTTP response to a `GET' or `HEAD' request for
    that document.

    An HTTP server must not use the <META> element to form an HTTP
    response header unless the HTTP-EQUIV attribute is present.

    An HTTP server may disregard any <META> elements that specify
    information controlled by the HTTP server, for example `Server',

    `Date', and `Last-modified'.

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.2.6. Next Id: NEXTID

   The <NEXTID> element is included for historical reasons only.  HTML
   documents should not contain <NEXTID> elements.

   The <NEXTID> element gives a hint for the name to use for a new <A>
   element when editing an HTML document. It should be distinct from all
   NAME attribute values on <A> elements. For example:

   <NEXTID N=Z27>

5.3. Body: BODY

   The <BODY> element contains the text flow of the document, including
   headings, paragraphs, lists, etc.

   For example:

    <BODY>
    <h1>Important Stuff</h1>
    <p>Explanation about important stuff...
    </BODY>

5.4. Headings: H1 ... H6

   The six heading elements, <H1> through <H6>, denote section headings.
   Although the order and occurrence of headings is not constrained by
   the HTML DTD, documents should not skip levels (for example, from H1
   to H3), as converting such documents to other representations is
   often problematic.

   Example of use:

    <H1>This is a heading</H1>
    Here is some text
    <H2>Second level heading</H2>
    Here is some more text.

    Typical renderings are:

    H1
            Bold, very-large font, centered. One or two blank lines
            above and below.

    H2
            Bold, large font, flush-left. One or two blank lines
            above and below.

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    H3
            Italic, large font, slightly indented from the left
            margin. One or two blank lines above and below.

    H4
            Bold, normal font, indented more than H3. One blank line
            above and below.

    H5
            Italic, normal font, indented as H4. One blank line
            above.

    H6
            Bold, indented same as normal text, more than H5. One
            blank line above.

5.5. Block Structuring Elements

   Block structuring elements include paragraphs, lists, and block
   quotes. They must not contain heading elements, but they may contain
   phrase markup, and in some cases, they may be nested.

5.5.1. Paragraph: P

   The <P> element indicates a paragraph. The exact indentation, leading
   space, etc. of a paragraph is not specified and may be a function of
   other tags, style sheets, etc.

   Typically, paragraphs are surrounded by a vertical space of one line
   or half a line. The first line in a paragraph is indented in some
   cases.

   Example of use:

    <H1>This Heading Precedes the Paragraph</H1>
    <P>This is the text of the first paragraph.
    <P>This is the text of the second paragraph. Although you do not
    need to start paragraphs on new lines, maintaining this
    convention facilitates document maintenance.</P>
    <P>This is the text of a third paragraph.</P>

5.5.2. Preformatted Text: PRE

   The <PRE> element represents a character cell block of text and is
   suitable for text that has been formatted for a monospaced font.

   The <PRE> tag may be used with the optional WIDTH attribute. The
   WIDTH attribute specifies the maximum number of characters for a line



Berners-Lee & Connolly      Standards Track                    [Page 25]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   and allows the HTML user agent to select a suitable font and
   indentation.

   Within preformatted text:

        * Line breaks within the text are rendered as a move to the
        beginning of the next line.

            NOTE - References to the "beginning of a new line"
            do not imply that the renderer is forbidden from
            using a constant left indent for rendering
            preformatted text. The left indent may be
            constrained by the width required.

        * Anchor elements and phrase markup may be used.

            NOTE - Constraints on the processing of <PRE>
            content may limit or prevent the ability of the HTML
            user agent to faithfully render phrase markup.

        * Elements that define paragraph formatting (headings,
        address, etc.) must not be used.

            NOTE - Some historical documents contain <P> tags in
            <PRE> elements. User agents are encouraged to treat
            this as a line break. A <P> tag followed by a
            newline character should produce only one line
            break, not a line break plus a blank line.

        * The horizontal tab character (code position 9 in the HTML
        document character set) must be interpreted as the smallest
        positive nonzero number of spaces which will leave the
        number of characters so far on the line as a multiple of 8.
        Documents should not contain tab characters, as they are not
        supported consistently.

    Example of use:

    <PRE>
    Line 1.
           Line 2 is to the right of line 1.     <a href="abc">abc</a>
           Line 3 aligns with line 2.            <a href="def">def</a>
    </PRE>








Berners-Lee & Connolly      Standards Track                    [Page 26]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.5.2.1. Example and Listing: XMP, LISTING

   The <XMP> and <LISTING> elements are similar to the <PRE> element,
   but they have a different syntax. Their content is declared as CDATA,
   which means that no markup except the end-tag open delimiter-in-
   context is recognized (see 9.6 "Delimiter Recognition" of [SGML]).

      NOTE - In a previous draft of the HTML specification, the syntax
      of <XMP> and <LISTING> elements allowed closing tags to be treated
      as data characters, as long as the tag name was not <XMP> or
      <LISTING>, respectively.

   Since CDATA declared content has a number of unfortunate interactions
   with processing techniques and tends to be used and implemented
   inconsistently, HTML documents should not contain <XMP> nor <LISTING>
   elements -- the <PRE> tag is more expressive and more consistently
   supported.

   The <LISTING> element should be rendered so that at least 132
   characters fit on a line. The <XMP> element should be rendered so
   that at least 80 characters fit on a line but is otherwise identical
   to the <LISTING> element.

      NOTE - In a previous draft, HTML included a <PLAINTEXT> element
      that is similar to the <LISTING> element, except that there is no
      closing tag: all characters after the <PLAINTEXT> start-tag are
      data.

5.5.3. Address: ADDRESS

   The <ADDRESS> element contains such information as address, signature
   and authorship, often at the beginning or end of the body of a
   document.

   Typically, the <ADDRESS> element is rendered in an italic typeface
   and may be indented.

   Example of use:

    <ADDRESS>
    Newsletter editor<BR>
    J.R. Brown<BR>
    JimquickPost News, Jimquick, CT 01234<BR>
    Tel (123) 456 7890
    </ADDRESS>

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.5.4. Block Quote: BLOCKQUOTE

   The <BLOCKQUOTE> element contains text quoted from another source.

   A typical rendering might be a slight extra left and right indent,
   and/or italic font. The <BLOCKQUOTE> typically provides space above
   and below the quote.

   Single-font rendition may reflect the quotation style of Internet
   mail by putting a vertical line of graphic characters, such as the
   greater than symbol (>), in the left margin.

   Example of use:

    I think the play ends
    <BLOCKQUOTE>
    <P>Soft you now, the fair Ophelia. Nymph, in thy orisons, be all
    my sins remembered.
    </BLOCKQUOTE>
    but I am not sure.

5.6. List Elements

   HTML includes a number of list elements. They may be used in
   combination; for example, a <OL> may be nested in an <LI> element of
   a <UL>.

   The COMPACT attribute suggests that a compact rendering be used.

5.6.1. Unordered List: UL, LI

   The <UL> represents a list of items -- typically rendered as a
   bulleted list.

   The content of a <UL> element is a sequence of <LI> elements.  For
   example:

    <UL>
    <LI>First list item
    <LI>Second list item
     <p>second paragraph of second item
    <LI>Third list item
    </UL>

5.6.2. Ordered List: OL

   The <OL> element represents an ordered list of items, sorted by
   sequence or order of importance. It is typically rendered as a



Berners-Lee & Connolly      Standards Track                    [Page 28]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   numbered list.

   The content of a <OL> element is a sequence of <LI> elements.  For
   example:

    <OL>
    <LI>Click the Web button to open URI window.
    <LI>Enter the URI number in the text field of the Open URI
    window. The Web document you specified is displayed.
      <ol>
       <li>substep 1
       <li>substep 2
      </ol>
    <LI>Click highlighted text to move from one link to another.
    </OL>

5.6.3. Directory List: DIR

   The <DIR> element is similar to the <UL> element. It represents a
   list of short items, typically up to 20 characters each. Items in a
   directory list may be arranged in columns, typically 24 characters
   wide.

   The content of a <DIR> element is a sequence of <LI> elements.
   Nested block elements are not allowed in the content of <DIR>
   elements. For example:

    <DIR>
    <LI>A-H<LI>I-M
    <LI>M-R<LI>S-Z
    </DIR>

5.6.4. Menu List: MENU

   The <MENU> element is a list of items with typically one line per
   item. The menu list style is typically more compact than the style of
   an unordered list.

   The content of a <MENU> element is a sequence of <LI> elements.
   Nested block elements are not allowed in the content of <MENU>
   elements. For example:

    <MENU>
    <LI>First item in the list.
    <LI>Second item in the list.
    <LI>Third item in the list.
    </MENU>

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.6.5. Definition List: DL, DT, DD

   A definition list is a list of terms and corresponding definitions.
   Definition lists are typically formatted with the term flush-left and
   the definition, formatted paragraph style, indented after the term.

   The content of a <DL> element is a sequence of <DT> elements and/or
   <DD> elements, usually in pairs. Multiple <DT> may be paired with a
   single <DD> element. Documents should not contain multiple
   consecutive <DD> elements.

   Example of use:

    <DL>
    <DT>Term<DD>This is the definition of the first term.
    <DT>Term<DD>This is the definition of the second term.
    </DL>

   If the DT term does not fit in the DT column (typically one third of
   the display area), it may be extended across the page with the DD
   section moved to the next line, or it may be wrapped onto successive
   lines of the left hand column.

   The optional COMPACT attribute suggests that a compact rendering be
   used, because the list items are small and/or the entire list is
   large.

   Unless the COMPACT attribute is present, an HTML user agent may leave
   white space between successive DT, DD pairs. The COMPACT attribute
   may also reduce the width of the left-hand (DT) column.

    <DL COMPACT>
    <DT>Term<DD>This is the first definition in compact format.
    <DT>Term<DD>This is the second definition in compact format.
    </DL>

5.7. Phrase Markup

   Phrases may be marked up according to idiomatic usage, typographic
   appearance, or for use as hyperlink anchors.

   User agents must render highlighted phrases distinctly from plain
   text. Additionally, <EM> content must be rendered as distinct from
   <STRONG> content, and <B> content must rendered as distinct from <I>
   content.

   Phrase elements may be nested within the content of other phrase
   elements; however, HTML user agents may render nested phrase elements



Berners-Lee & Connolly      Standards Track                    [Page 30]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   indistinctly from non-nested elements:

   plain <B>bold <I>italic</I></B> may be rendered
   the same as plain <B>bold </B><I>italic</I>

5.7.1. Idiomatic Elements

   Phrases may be marked up to indicate certain idioms.

      NOTE - User agents may support the <DFN> element, not included in
      this specification, as it has been deployed to some extent. It is
      used to indicate the defining instance of a term, and it is
      typically rendered in italic or bold italic.

5.7.1.1. Citation: CITE

      The <CITE> element is used to indicate the title of a book or
      other citation. It is typically rendered as italics. For example:

      He just couldn't get enough of <cite>The Grapes of Wrath</cite>.

5.7.1.2. Code: CODE

      The <CODE> element indicates an example of code, typically
      rendered in a mono-spaced font. The <CODE> element is intended for
      short words or phrases of code; the <PRE> block structuring
      element (5.5.2, "Preformatted Text: PRE") is more appropriate
       for multiple-line listings. For example:

      The expression <code>x += 1</code>
      is short for <code>x = x + 1</code>.

5.7.1.3. Emphasis: EM

      The <EM> element indicates an emphasized phrase, typically
      rendered as italics. For example:

      A singular subject <em>always</em> takes a singular verb.

5.7.1.4. Keyboard: KBD

      The <KBD> element indicates text typed by a user, typically
      rendered in a mono-spaced font. This is commonly used in
      instruction manuals. For example:

      Enter <kbd>FIND IT</kbd> to search the database.





Berners-Lee & Connolly      Standards Track                    [Page 31]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.7.1.5. Sample: SAMP

      The <SAMP> element indicates a sequence of literal characters,
      typically rendered in a mono-spaced font. For example:

      The only word containing the letters <samp>mt</samp> is dreamt.

5.7.1.6. Strong Emphasis: STRONG

      The <STRONG> element indicates strong emphasis, typically rendered
      in bold. For example:

      <strong>STOP</strong>, or I'll say "<strong>STOP</strong>" again!

5.7.1.7. Variable: VAR

      The <VAR> element indicates a placeholder variable, typically
      rendered as italic. For example:

      Type <SAMP>html-check <VAR>file</VAR> | more</SAMP>
      to check <VAR>file</VAR> for markup errors.

5.7.2. Typographic Elements

      Typographic elements are used to specify the format of marked
      text.

      Typical renderings for idiomatic elements may vary between user
      agents. If a specific rendering is necessary -- for example, when
      referring to a specific text attribute as in "The italic parts are
      mandatory" -- a typographic element can be used to ensure that the
      intended typography is used where possible.

      NOTE - User agents may support some typographic elements not
      included in this specification, as they have been deployed to some
      extent. The <STRIKE> element indicates horizontal line through the
      characters, and the <U> element indicates an underline.

5.7.2.1. Bold: B

   The <B> element indicates bold text. Where bold typography is
   unavailable, an alternative representation may be used.

5.7.2.2. Italic: I

   The <I> element indicates italic text. Where italic typography is
   unavailable, an alternative representation may be used.




Berners-Lee & Connolly      Standards Track                    [Page 32]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


5.7.2.3. Teletype: TT

   The <TT> element indicates teletype (monospaced )text. Where a
   teletype font is unavailable, an alternative representation may be
   used.

5.7.3. Anchor: A

   The <A> element indicates a hyperlink anchor (see 7, "Hyperlinks").
   At least one of the NAME and HREF attributes should be present.
   Attributes of the <A> element:

    HREF
            gives the URI of the head anchor of a hyperlink.

    NAME
            gives the name of the anchor, and makes it available as
            a head of a hyperlink.

    TITLE
            suggests a title for the destination resource --
            advisory only. The TITLE attribute may be used:

                * for display prior to accessing the destination
                resource, for example, as a margin note or on a
                small box while the mouse is over the anchor, or
                while the document is being loaded;

                * for resources that do not include a title, such as
                graphics, plain text and Gopher menus, for use as a
                window title.

    REL
            The REL attribute gives the relationship(s) described by
            the hyperlink. The value is a whitespace separated list
            of relationship names. The semantics of link
            relationships are not specified in this document.

    REV
            same as the REL attribute, but the semantics of the
            relationship are in the reverse direction. A link from A
            to B with REL="X" expresses the same relationship as a
            link from B to A with REV="X". An anchor may have both
            REL and REV attributes.

    URN
            specifies a preferred, more persistent identifier for
            the head anchor of the hyperlink. The syntax and



Berners-Lee & Connolly      Standards Track                    [Page 33]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


            semantics of the URN attribute are not yet specified.

    METHODS
            specifies methods to be used in accessing the
            destination, as a whitespace-separated list of names.
            The set of applicable names is a function of the scheme
            of the URI in the HREF attribute. For similar reasons as
            for the TITLE attribute, it may be useful to include the
            information in advance in the link. For example, the
            HTML user agent may chose a different rendering as a
            function of the methods allowed; for example, something
            that is searchable may get a different icon.

5.8. Line Break: BR

   The <BR> element specifies a line break between words (see 6,
   "Characters, Words, and Paragraphs"). For example:

    <P> Pease porridge hot<BR>
    Pease porridge cold<BR>
    Pease porridge in the pot<BR>
    Nine days old.

5.9. Horizontal Rule: HR

   The <HR> element is a divider between sections of text; typically a
   full width horizontal rule or equivalent graphic.  For example:

    <HR>
    <ADDRESS>February 8, 1995, CERN</ADDRESS>
    </BODY>

5.10. Image: IMG

   The <IMG> element refers to an image or icon via a hyperlink (see
   7.3, "Simultaneous Presentation of Image Resources").

   HTML user agents may process the value of the ALT attribute as an
   alternative to processing the image resource indicated by the SRC
   attribute.

      NOTE - Some HTML user agents can process graphics linked via
      anchors, but not <IMG> graphics. If a graphic is essential, it
      should be referenced from an <A> element rather than an <IMG>
      element. If the graphic is not essential, then the <IMG> element
      is appropriate.

   Attributes of the <IMG> element:



Berners-Lee & Connolly      Standards Track                    [Page 34]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    ALIGN
            alignment of the image with respect to the text
            baseline.

                * `TOP' specifies that the top of the image aligns
                with the tallest item on the line containing the
                image.

                * `MIDDLE' specifies that the center of the image
                aligns with the baseline of the line containing the
                image.

                * `BOTTOM' specifies that the bottom of the image
                aligns with the baseline of the line containing the
                image.

    ALT
            text to use in place of the referenced image resource,
            for example due to processing constraints or user
            preference.

    ISMAP
            indicates an image map (see 7.6, "Image Maps").

    SRC
            specifies the URI of the image resource.

                NOTE - In practice, the media types of image
                resources are limited to a few raster graphic
                formats: typically `image/gif', `image/jpeg'. In
                particular, `text/html' resources are not
                intended to be used as image resources.

    Examples of use:

    <IMG SRC="triangle.xbm" ALT="Warning:"> Be sure
    to read these instructions.

    <a href="http://machine/htbin/imagemap/sample">
    <IMG SRC="sample.xbm" ISMAP>
    </a>

6. Characters, Words, and Paragraphs

   An HTML user agent should present the body of an HTML document as a
   collection of typeset paragraphs and preformatted text.  Except for
   preformatted elements (<PRE>, <XMP>, <LISTING>, <TEXTAREA>), each
   block structuring element is regarded as a paragraph by taking the



Berners-Lee & Connolly      Standards Track                    [Page 35]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   data characters in its content and the content of its descendant
   elements, concatenating them, and splitting the result into words,
   separated by space, tab, or record end characters (and perhaps hyphen
   characters). The sequence of words is typeset as a paragraph by
   breaking it into lines.

6.1. The HTML Document Character Set

   The document character set specified in 9.5, "SGML Declaration for
   HTML" must be supported by HTML user agents. It includes the graphic
   characters of Latin Alphabet No. 1, or simply Latin-1.  Latin-1
   comprises 191 graphic characters, including the alphabets of most
   Western European languages.

      NOTE - Use of the non-breaking space and soft hyphen indicator
      characters is discouraged because support for them is not widely
      deployed.

      NOTE - To support non-western writing systems, a larger character
      repertoire will be specified in a future version of HTML. The
      document character set will be [ISO-10646], or some subset that
      agrees with [ISO-10646]; in particular, all numeric character
      references must use code positions assigned by [ISO-10646].

   In SGML applications, the use of control characters is limited in
   order to maximize the chance of successful interchange over
   heterogeneous networks and operating systems. In the HTML document
   character set only three control characters are allowed: Horizontal
   Tab, Carriage Return, and Line Feed (code positions 9, 13, and 10).

   The HTML DTD references the Added Latin 1 entity set, to allow
   mnemonic representation of selected Latin 1 characters using only the
   widely supported ASCII character repertoire. For example:

   Kurt G&ouml;del was a famous logician and mathematician.

   See 9.7.2, "ISO Latin 1 Character Entity Set" for a table of the
   "Added Latin 1" entities, and 13, "The HTML Coded Character Set" for
   a table of the code positions of [ISO 8859-1] and the control
   characters in the HTML document character set.

7. Hyperlinks

   In addition to general purpose elements such as paragraphs and lists,
   HTML documents can express hyperlinks. An HTML user agent allows the
   user to navigate these hyperlinks.





Berners-Lee & Connolly      Standards Track                    [Page 36]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   A hyperlink is a relationship between two anchors, called the head
   and the tail of the hyperlink[DEXTER]. Anchors are identified by an
   anchor address: an absolute Uniform Resource Identifier (URI),
   optionally followed by a '#' and a sequence of characters called a
   fragment identifier. For example:

   http://www.w3.org/hypertext/WWW/TheProject.html
   http://www.w3.org/hypertext/WWW/TheProject.html#z31

   In an anchor address, the URI refers to a resource; it may be used in
   a variety of information retrieval protocols to obtain an entity that
   represents the resource, such as an HTML document. The fragment
   identifier, if present, refers to some view on, or portion of the
   resource.

   Each of the following markup constructs indicates the tail anchor of
   a hyperlink or set of hyperlinks:

        * <A> elements with HREF present.

        * <LINK> elements.

        * <IMG> elements.

        * <INPUT> elements with the SRC attribute present.

        * <ISINDEX> elements.

        * <FORM> elements with `METHOD=GET'.

   These markup constructs refer to head anchors by a URI, either
   absolute or relative, or a fragment identifier, or both.

   In the case of a relative URI, the absolute URI in the address of the
   head anchor is the result of combining the relative URI with a base
   absolute URI as in [RELURL]. The base document is taken from the
   document's <BASE> element, if present; else, it is determined as in
   [RELURL].

7.1. Accessing Resources

   Once the address of the head anchor is determined, the user agent may
   obtain a representation of the resource.

   For example, if the base URI is `http://host/x/y.html' and the
   document contains:

   <img src="../icons/abc.gif">



Berners-Lee & Connolly      Standards Track                    [Page 37]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   then the user agent uses the URI `http://host/icons/abc.gif' to
   access the resource, as in [URL]..

7.2. Activation of Hyperlinks

   An HTML user agent allows the user to navigate the content of the
   document and request activation of hyperlinks denoted by <A>
   elements. HTML user agents should also allow activation of <LINK>
   element hyperlinks.

   To activate a link, the user agent obtains a representation of the
   resource identified in the address of the head anchor. If the
   representation is another HTML document, navigation may begin again
   with this new document.

7.3. Simultaneous Presentation of Image Resources

   An HTML user agent may activate hyperlinks indicated by <IMG> and
   <INPUT> elements concurrently with processing the document; that is,
   image hyperlinks may be processed without explicit request by the
   user. Image resources should be embedded in the presentation at the
   point of the tail anchor, that is the <IMG> or <INPUT> element.

   <LINK> hyperlinks may also be processed without explicit user
   request; for example, style sheet resources may be processed before
   or during the processing of the document.

7.4. Fragment Identifiers

   Any characters following a `#' character in a hypertext address
   constitute a fragment identifier. In particular, an address of the
   form `#fragment' refers to an anchor in the same document.

   The meaning of fragment identifiers depends on the media type of the
   representation of the anchor's resource. For `text/html'
   representations, it refers to the <A> element with a NAME attribute
   whose value is the same as the fragment identifier.  The matching is
   case sensitive. The document should have exactly one such element.
   The user agent should indicate the anchor element, for example by
   scrolling to and/or highlighting the phrase.

   For example, if the base URI is `http://host/x/y.html' and the user
   activated the link denoted by the following markup:

   <p> See: <a href="app1.html#bananas">appendix 1</a>
   for more detail on bananas.





Berners-Lee & Connolly      Standards Track                    [Page 38]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   Then the user agent accesses the resource identified by
   `http://host/x/app1.html'. Assuming the resource is represented using
   the `text/html' media type, the user agent must locate the <A>
   element whose NAME attribute is `bananas' and begin navigation there.

7.5. Queries and Indexes

   The <ISINDEX> element represents a set of hyperlinks. The user can
   choose from the set by providing keywords to the user agent.  The
   user agent computes the head URI by appending `?' and the keywords to
   the base URI. The keywords are escaped according to [URL] and joined
   by `+'. For example, if a document contains:

    <BASE HREF="http://host/index">
    <ISINDEX>

    and the user provides the keywords `apple' and `berry', then the
    user agent must access the resource
    `http://host/index?apple+berry'.

    <FORM> elements with `METHOD=GET' also represent sets of
    hyperlinks. See 8.2.2, "Query Forms: METHOD=GET" for details.

7.6. Image Maps

   If the ISMAP attribute is present on an <IMG> element, the <IMG>
   element must be contained in an <A> element with an HREF present.
   This construct represents a set of hyperlinks. The user can choose
   from the set by choosing a pixel of the image. The user agent
   computes the head URI by appending `?' and the x and y coordinates of
   the pixel to the URI given in the <A> element.  For example, if a
   document contains:

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
   <head><title>ImageMap Example</title>
   <BASE HREF="http://host/index"></head>
   <body>
   <p> Choose any of these icons:<br>
   <a href="/cgi-bin/imagemap"><img ismap src="icons.gif"></a>

   and the user chooses the upper-leftmost pixel, the chosen
   hyperlink is the one with the URI
   `http://host/cgi-bin/imagemap?0,0'.

RFC 1866            Hypertext Markup Language - 2.0        November 1995


8. Forms

   A form is a template for a form data set and an associated
   method and action URI. A form data set is a sequence of
   name/value pair fields. The names are specified on the NAME
   attributes of form input elements, and the values are given
   initial values by various forms of markup and edited by the
   user. The resulting form data set is used to access an
   information service as a function of the action and method.

   Forms elements can be mixed in with document structuring
   elements. For example, a <PRE> element may contain a <FORM>
   element, or a <FORM> element may contain lists which contain
   <INPUT> elements. This gives considerable flexibility in
   designing the layout of forms.

   Form processing is a level 2 feature.

8.1. Form Elements

8.1.1. Form: FORM

   The <FORM> element contains a sequence of input elements, along
   with document structuring elements. The attributes are:

    ACTION
            specifies the action URI for the form. The action URI of
            a form defaults to the base URI of the document (see 7,
            "Hyperlinks").

    METHOD
            selects a method of accessing the action URI. The set of
            applicable methods is a function of the scheme of the
            action URI of the form. See 8.2.2, "Query Forms:
            METHOD=GET" and 8.2.3, "Forms with Side-Effects:
            METHOD=POST".

    ENCTYPE
            specifies the media type used to encode the name/value
            pairs for transport, in case the protocol does not
            itself impose a format. See 8.2.1, "The form-urlencoded
            Media Type".

8.1.2. Input Field: INPUT

   The <INPUT> element represents a field for user input. The TYPE
   attribute discriminates between several variations of fields.




Berners-Lee & Connolly      Standards Track                    [Page 40]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   The <INPUT> element has a number of attributes. The set of applicable
   attributes depends on the value of the TYPE attribute.

8.1.2.1. Text Field: INPUT TYPE=TEXT

   The default value of the TYPE attribute is `TEXT', indicating a
   single line text entry field. (Use the <TEXTAREA> element for multi-
   line text fields.)

   Required attributes are:

    NAME
            name for the form field corresponding to this element.

    The optional attributes are:

    MAXLENGTH
            constrains the number of characters that can be entered
            into a text input field. If the value of MAXLENGTH is
            greater the the value of the SIZE attribute, the field
            should scroll appropriately. The default number of
            characters is unlimited.

    SIZE
            specifies the amount of display space allocated to this
            input field according to its type. The default depends
            on the user agent.

    VALUE
            The initial value of the field.

    For example:

<p>Street Address: <input name=street><br>
Postal City code: <input name=city size=16 maxlength=16><br>
Zip Code: <input name=zip size=10 maxlength=10 value="99999-9999"><br>

8.1.2.2. Password Field: INPUT TYPE=PASSWORD

   An <INPUT> element with `TYPE=PASSWORD' is a text field as above,
   except that the value is obscured as it is entered. (see also: 10,
   "Security Considerations").

   For example:

<p>Name: <input name=login> Password: <input type=password name=passwd>

8.1.2.3. Check Box: INPUT TYPE=CHECKBOX

   An <INPUT> element with `TYPE=CHECKBOX' represents a boolean choice.
   A set of such elements with the same name represents an n-of-many
   choice field. Required attributes are:

    NAME
            symbolic name for the form field corresponding to this
            element or group of elements.

    VALUE
            The portion of the value of the field contributed by
            this element.

    Optional attributes are:

    CHECKED
            indicates that the initial state is on.

    For example:

  <p>What flavors do you like?
  <input type=checkbox name=flavor value=vanilla>Vanilla<br>
  <input type=checkbox name=flavor value=strawberry>Strawberry<br>
  <input type=checkbox name=flavor value=chocolate checked>Chocolate<br>

8.1.2.4. Radio Button: INPUT TYPE=RADIO

   An <INPUT> element with `TYPE=RADIO' represents a boolean choice. A
   set of such elements with the same name represents a 1-of-many choice
   field. The NAME and VALUE attributes are required as for check boxes.
   Optional attributes are:

    CHECKED
            indicates that the initial state is on.
   At all times, exactly one of the radio buttons in a set is checked.
   If none of the <INPUT> elements of a set of radio buttons specifies
   `CHECKED', then the user agent must check the first radio button of
   the set initially.

   For example:

    <p>Which is your favorite?
    <input type=radio name=flavor value=vanilla>Vanilla<br>
    <input type=radio name=flavor value=strawberry>Strawberry<br>
    <input type=radio name=flavor value=chocolate>Chocolate<br>

8.1.2.5. Image Pixel: INPUT TYPE=IMAGE

   An <INPUT> element with `TYPE=IMAGE' specifies an image resource to
   display, and allows input of two form fields: the x and y coordinate
   of a pixel chosen from the image. The names of the fields are the
   name of the field with `.x' and `.y' appended.  `TYPE=IMAGE' implies
   `TYPE=SUBMIT' processing; that is, when a pixel is chosen, the form
   as a whole is submitted.

   The NAME attribute is required as for other input fields. The SRC
   attribute is required and the ALIGN is optional as for the <IMG>
   element (see 5.10, "Image: IMG").

   For example:

    <p>Choose a point on the map:
    <input type=image name=point src="map.gif">

8.1.2.6. Hidden Field: INPUT TYPE=HIDDEN

   An <INPUT> element with `TYPE=HIDDEN' represents a hidden field.The
   user does not interact with this field; instead, the VALUE attribute
   specifies the value of the field. The NAME and VALUE attributes are
   required.

   For example:

   <input type=hidden name=context value="l2k3j4l2k3j4l2k3j4lk23">

8.1.2.7. Submit Button: INPUT TYPE=SUBMIT

   An <INPUT> element with `TYPE=SUBMIT' represents an input option,
   typically a button, that instructs the user agent to submit the form.
   Optional attributes are:

    NAME
            indicates that this element contributes a form field
            whose value is given by the VALUE attribute. If the NAME
            attribute is not present, this element does not
            contribute a form field.

    VALUE
            indicates a label for the input (button).

    You may submit this request internally:
    <input type=submit name=recipient value=internal><br>
    or to the external world:
    <input type=submit name=recipient value=world>

RFC 1866            Hypertext Markup Language - 2.0        November 1995


8.1.2.8. Reset Button: INPUT TYPE=RESET

   An <INPUT> element with `TYPE=RESET' represents an input option,
   typically a button, that instructs the user agent to reset the form's
   fields to their initial states. The VALUE attribute, if present,
   indicates a label for the input (button).

   When you are finished, you may submit this request:
   <input type=submit><br>
   You may clear the form and start over at any time: <input type=reset>

8.1.3. Selection: SELECT

   The <SELECT> element constrains the form field to an enumerated list
   of values. The values are given in <OPTION> elements.  Attributes
   are:

    MULTIPLE
            indicates that more than one option may be included in
            the value.

    NAME
            specifies the name of the form field.

    SIZE
            specifies the number of visible items. Select fields of
            size one are typically pop-down menus, whereas select
            fields with size greater than one are typically lists.

    For example:

    <SELECT NAME="flavor">
    <OPTION>Vanilla
    <OPTION>Strawberry
    <OPTION value="RumRasin">Rum and Raisin
    <OPTION selected>Peach and Orange
    </SELECT>

   The initial state has the first option selected, unless a SELECTED
   attribute is present on any of the <OPTION> elements.

8.1.3.1. Option: OPTION

   The Option element can only occur within a Select element. It
   represents one choice, and has the following attributes:

    SELECTED
            Indicates that this option is initially selected.



Berners-Lee & Connolly      Standards Track                    [Page 44]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    VALUE
            indicates the value to be returned if this option is
            chosen. The field value defaults to the content of the
            <OPTION> element.

   The content of the <OPTION> element is presented to the user to
   represent the option. It is used as a returned value if the VALUE
   attribute is not present.

8.1.4. Text Area: TEXTAREA

   The <TEXTAREA> element represents a multi-line text field.
   Attributes are:

    COLS
            the number of visible columns to display for the text
            area, in characters.

    NAME
            Specifies the name of the form field.

    ROWS
            The number of visible rows to display for the text area,
            in characters.

    For example:

    <TEXTAREA NAME="address" ROWS=6 COLS=64>
    HaL Computer Systems
    1315 Dell Avenue
    Campbell, California 95008
    </TEXTAREA>

   The content of the <TEXTAREA> element is the field's initial value.

   Typically, the ROWS and COLS attributes determine the visible
   dimension of the field in characters. The field is typically rendered
   in a fixed-width font. HTML user agents should allow text to extend
   beyond these limits by scrolling as needed.

8.2. Form Submission

   An HTML user agent begins processing a form by presenting the
   document with the fields in their initial state. The user is allowed
   to modify the fields, constrained by the field type etc.  When the
   user indicates that the form should be submitted (using a submit
   button or image input), the form data set is processed according to
   its method, action URI and enctype.



Berners-Lee & Connolly      Standards Track                    [Page 45]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   When there is only one single-line text input field in a form, the
   user agent should accept Enter in that field as a request to submit
   the form.

8.2.1. The form-urlencoded Media Type

   The default encoding for all forms is `application/x-www-form-
   urlencoded'. A form data set is represented in this media type as
   follows:

        1. The form field names and values are escaped: space
        characters are replaced by `+', and then reserved characters
        are escaped as per [URL]; that is, non-alphanumeric
        characters are replaced by `%HH', a percent sign and two
        hexadecimal digits representing the ASCII code of the
        character. Line breaks, as in multi-line text field values,
        are represented as CR LF pairs, i.e. `%0D%0A'.

        2. The fields are listed in the order they appear in the
        document with the name separated from the value by `=' and
        the pairs separated from each other by `&'. Fields with null
        values may be omitted. In particular, unselected radio
        buttons and checkboxes should not appear in the encoded
        data, but hidden fields with VALUE attributes present
        should.

            NOTE - The URI from a query form submission can be
            used in a normal anchor style hyperlink.
            Unfortunately, the use of the `&' character to
            separate form fields interacts with its use in SGML
            attribute values as an entity reference delimiter.
            For example, the URI `http://host/?x=1&y=2' must be
            written `<a href="http://host/?x=1&#38;y=2"' or `<a
            href="http://host/?x=1&amp;y=2">'.

            HTTP server implementors, and in particular, CGI
            implementors are encouraged to support the use of
            `;' in place of `&' to save users the trouble of
            escaping `&' characters this way.

8.2.2. Query Forms: METHOD=GET

   If the processing of a form is idempotent (i.e. it has no lasting
   observable effect on the state of the world), then the form method
   should be `GET'. Many database searches have no visible side-effects
   and make ideal applications of query forms.





Berners-Lee & Connolly      Standards Track                    [Page 46]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   To process a form whose action URL is an HTTP URL and whose method is
   `GET', the user agent starts with the action URI and appends a `?'
   and the form data set, in `application/x-www-form-urlencoded' format
   as above. The user agent then traverses the link to this URI just as
   if it were an anchor (see 7.2, "Activation of Hyperlinks").

      NOTE - The URL encoding may result in very long URIs, which cause
      some historical HTTP server implementations to exhibit defective
      behavior. As a result, some HTML forms are written using
      `METHOD=POST' even though the form submission has no side-effects.

8.2.3. Forms with Side-Effects: METHOD=POST

   If the service associated with the processing of a form has side
   effects (for example, modification of a database or subscription to a
   service), the method should be `POST'.

   To process a form whose action URL is an HTTP URL and whose method is
   `POST', the user agent conducts an HTTP POST transaction using the
   action URI, and a message body of type `application/x-www-form-
   urlencoded' format as above. The user agent should display the
   response from the HTTP POST interaction just as it would display the
   response from an HTTP GET above.

8.2.4. Example Form Submission: Questionnaire Form

   Consider the following document:

    <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
    <title>Sample of HTML Form Submission</title>
    <H1>Sample Questionnaire</H1>
    <P>Please fill out this questionnaire:
    <FORM METHOD="POST" ACTION="http://www.w3.org/sample">
    <P>Your name: <INPUT NAME="name" size="48">
    <P>Male <INPUT NAME="gender" TYPE=RADIO VALUE="male">
    <P>Female <INPUT NAME="gender" TYPE=RADIO VALUE="female">

RFC 1866            Hypertext Markup Language - 2.0        November 1995


    The initial state of the form data set is:

    name
            ""

    gender
            "male"

    family
            ""

    other
            ""

    nickname
            ""

    Note that the radio input has an initial value, while the
    checkbox has none.

    The user might edit the fields and request that the form be
    submitted. At that point, suppose the values are:

    name
            "John Doe"

    gender
            "male"

    family
            "5"

    city
            "kent"

    city
            "miami"

    other
            "abc\ndefk"

    nickname
            "J&D"

   The user agent then conducts an HTTP POST transaction using the URI
   `http://www.w3.org/sample'. The message body would be (ignore the
   line break):

9.6. Sample SGML Open Entity Catalog for HTML

   The SGML standard describes an "entity manager" as the portion or
   component of an SGML system that maps SGML entities into the actual
   storage model (e.g., the file system). The standard itself does not



Berners-Lee & Connolly      Standards Track                    [Page 65]

RFC 1866            Hypertext Markup Language - 2.0        November 1995


   define a particular mapping methodology or notation.

   To assist the interoperability among various SGML tools and systems,
   the SGML Open consortium has passed a technical resolution that
   defines a format for an application-independent entity catalog that
   maps external identifiers and/or entity names to file names.

   Each entry in the catalog associates a storage object identifier
   (such as a file name) with information about the external entity that
   appears in the SGML document. In addition to entries that associate
   public identifiers, a catalog entry can associate an entity name with
   a storage object identifier. For example, the following are possible
   catalog entries:

   for use, and description. This list is derived from `ISO Standard
   8879:1986//ENTITIES Numeric and Special Graphic//EN'.  However, HTML
   does not include for the entire entity set -- only the entities
   listed below are included.

10. Security Considerations

   Anchors, embedded images, and all other elements which contain URIs
   as parameters may cause the URI to be dereferenced in response to
   user input. In this case, the security considerations of [URL] apply.

   The widely deployed methods for submitting forms requests -- HTTP and
   SMTP -- provide little assurance of confidentiality.  Information
   providers who request sensitive information via forms -- especially
   by way of the `PASSWORD' type input field (see 8.1.2, "Input Field:
   INPUT") -- should be aware and make their users aware of the lack of
   confidentiality.

12. Acknowledgments

   The HTML document type was designed by Tim Berners-Lee at CERN as
   part of the 1990 World Wide Web project. In 1992, Dan Connolly wrote
   the HTML Document Type Definition (DTD) and a brief HTML
   specification.

   Since 1993, a wide variety of Internet participants have contributed
   to the evolution of HTML, which has included the addition of in-line
   images introduced by the NCSA Mosaic software for WWW. Dave Raggett
   played an important role in deriving the forms material from the
   HTML+ specification.

   Dan Connolly and Karen Olson Muldrow rewrote the HTML Specification
   in 1994. The document was then edited by the HTML working group as a
   whole, with updates being made by Eric Schieler, Mike Knezovich, and
   Eric W. Sink at Spyglass, Inc.  Finally, Roy Fielding restructured
   the entire draft into its current form.

   Special thanks to the many active participants in the HTML working
   group, too numerous to list individually, without whom there would be
   no standards process and no standard. That this document approaches
   its objective of carefully converging a description of current
   practice and formalization of HTML's relationship to SGML is a
   tribute to their effort.

14. Proposed Entities

   The HTML DTD references the "Added Latin 1" entity set, which only
   supplies named entities for a subset of the non-ASCII characters in
   [ISO-8859-1], namely the accented characters. The following entities
   should be supported so that all ISO 8859-1 characters may only be
   referenced symbolically. The names for these entities are taken from
   the appendixes of [SGML].

This name is used in the title of most generated pages and in a few other places. PROJECT_NUMBER = "@VERSION@" # The PROJECT_NUMBER tag can be used to enter a project or revision number. This could be handy for archiving the generated documentation or if some version control system is used. CHM_FILE = "..\@PACKAGE@-@VERSION@.chm" # If the GENERATE_HTMLHELP tag is set to YES, the CHM_FILE tag can be used to specify the file name of the resulting .chm file. You can add a path in front of the file if the result should not be written to the html output directory. OUTPUT_DIRECTORY = . # The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) path into which the generated documentation will be written. If a relative path is entered, it will be relative to the location where doxygen was started. If left blank the current directory will be used. # CREATE_SUBDIRS = # If the CREATE_SUBDIRS tag is set to YES, then doxygen will create 4096 sub-directories (in 2 levels) under the output directory of each output format and will distribute the generated files over these directories. Enabling this option can be useful when feeding doxygen a huge amount of source files, where putting all generated files in the same directory would otherwise causes performance problems for the file system. # OUTPUT_LANGUAGE = # The OUTPUT_LANGUAGE tag is used to specify the language in which all documentation generated by doxygen is written. Doxygen will use this information to generate all constant output in the proper language. The default language is English, other supported languages are: Afrikaans, Arabic, Brazilian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Lithuanian, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, Swedish, and Ukrainian. # USE_WINDOWS_ENCODING = # This tag can be used to specify the encoding used in the generated output. The encoding is not always determined by the language that is chosen, but also whether or not the output is meant for Windows or non-Windows users. In case there is a difference, setting the USE_WINDOWS_ENCODING tag to YES forces the Windows encoding, (this is the default for the Windows binary), whereas setting the tag to NO uses a Unix-style encoding (the default for all platforms other than Windows). # BRIEF_MEMBER_DESC = # If the BRIEF_MEMBER_DESC tag is set to YES (the default) doxygen will include brief member descriptions after the members that are listed in the file and class documentation (similar to JavaDoc). Set to NO to disable this. # REPEAT_BRIEF = # If the REPEAT_BRIEF tag is set to YES (the default) doxygen will prepend the brief description of a member or function before the detailed description # # Note: # If both HIDE_UNDOC_MEMBERS and BRIEF_MEMBER_DESC are set to NO, the brief descriptions will be completely suppressed. # ABBREVIATE_BRIEF = # This tag implements a quasi-intelligent brief description abbreviator that is used to form the text in various listings. Each string in this list, if found as the leading text of the brief description, will be stripped from the text and the result after processing the whole list, is used as the annotated text. Otherwise, the brief description is used as-is. If left blank, the following values are used ("\$name" is automatically replaced with the name of the entity): "The $name class" "The $name widget" "The $name file" "is" "provides" "specifies" "contains" "represents" "a" "an" "the". # ALWAYS_DETAILED_SEC = # If the ALWAYS_DETAILED_SEC and REPEAT_BRIEF tags are both set to YES then doxygen will generate a detailed section even if there is only a brief description. # INLINE_INHERITED_MEMB = # If the INLINE_INHERITED_MEMB tag is set to YES, doxygen will show all inherited members of a class in the documentation of that class as if those members were ordinary class members. Constructors, destructors and assignment operators of the base classes will not be shown. FULL_PATH_NAMES = NO # If the FULL_PATH_NAMES tag is set to YES doxygen will prepend the full path before files name in the file list and in the header files. If set to NO the shortest path that makes the file name unique will be used # STRIP_FROM_PATH = # If the FULL_PATH_NAMES tag is set to YES then the STRIP_FROM_PATH tag can be used to strip a user-defined part of the path. Stripping is only done if one of the specified strings matches the left-hand part of the path. The tag can be used to show relative paths in the file list. If left blank the directory from which doxygen is run is used as the path to strip. # STRIP_FROM_INC_PATH = # The STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of the path mentioned in the documentation of a class, which tells the reader which header file to include in order to use a class. If left blank only the name of the header file containing the class definition is used. Otherwise one should specify the include paths that are normally passed to the compiler using the -I flag. # CASE_SENSE_NAMES = # If the CASE_SENSE_NAMES tag is set to NO then doxygen will only generate file names in lower-case letters. If set to YES upper-case letters are also allowed. This is useful if you have classes or files whose names only differ in case and if your file system supports case sensitive file names. Windows users are advised to set this option to NO. # SHORT_NAMES = # If the SHORT_NAMES tag is set to YES, doxygen will generate much shorter (but less readable) file names. This can be useful is your file systems doesn't support long names like on DOS, Mac, or CD-ROM. # JAVADOC_AUTOBRIEF = # If the JAVADOC_AUTOBRIEF is set to YES then doxygen will interpret the first line (until the first dot) of a JavaDoc-style comment as the brief description. If set to NO (the default), the Javadoc-style will behave just like the Qt-style comments. BUILTIN_STL_SUPPORT = NO # If you use STL classes (i.e. std::string, std::vector, etc.) but do not want to include (a tag file for) the STL sources as input, then you should set this tag to YES in order to let doxygen match functions declarations and definitions whose arguments contain STL classes (e.g. func(std::string); v.s. func(std::string) {}). This also make the inheritance and collaboration diagrams that involve STL classes more complete and accurate. # DISTRIBUTE_GROUP_DOC = # If member grouping is used in the documentation and the DISTRIBUTE_GROUP_DOC tag is set to YES, then doxygen will reuse the documentation of the first member in the group (if any) for the other members of the group. By default all members of a group must be documented explicitly. # MULTILINE_CPP_IS_BRIEF = # The MULTILINE_CPP_IS_BRIEF tag can be set to YES to make Doxygen treat a multi-line C++ special comment block (i.e. a block of //! or /// comments) as a brief description. This used to be the default behaviour. The new default is to treat a multi-line C++ comment block as a detailed description. Set this tag to YES if you prefer the old behaviour instead. Note that setting this tag to YES also means that rational rose comments are not recognized any more. # INHERIT_DOCS = # If the INHERIT_DOCS tag is set to YES (the default) then an undocumented member inherits the documentation from any documented member that it re-implements. # SEPARATE_MEMBER_PAGES = # If the SEPARATE_MEMBER_PAGES tag is set to YES, then doxygen will produce a new page for each member. If set to NO, the documentation of a member will be part of the file/class/namespace that contains it. # TAB_SIZE = # the TAB_SIZE tag can be used to set the number of spaces in a tab. Doxygen uses this value to replace tabs by spaces in code fragments. # ALIASES = # This tag can be used to specify a number of aliases that acts as commands in the documentation. An alias has the form # # name=value # # For example adding # # "sideeffect=\par Side Effects:\n" # # will allow you to put the command \sideeffect (or @sideeffect) in the documentation, which will result in a user-defined paragraph with heading "Side Effects:". You can put \n's in the value part of an alias to insert newlines. OPTIMIZE_OUTPUT_FOR_C = YES # Set the OPTIMIZE_OUTPUT_FOR_C tag to YES if your project consists of C sources only. Doxygen will then generate output that is more tailored for C. For instance, some of the names that are used will be different. The list of all members will be omitted, etc. # OPTIMIZE_OUTPUT_JAVA = # Set the OPTIMIZE_OUTPUT_JAVA tag to YES if your project consists of Java or Python sources only. Doxygen will then generate output that is more tailored for that language. For instance, namespaces will be presented as packages, qualified scopes will look different, etc. # SUBGROUPING = # Set the SUBGROUPING tag to YES (the default) to allow class member groups of the same type (for instance a group of public functions) to be put as a subgroup of that type (e.g. under the Public Functions section). Set it to NO to prevent subgrouping. Alternatively, this can be done per class using the \nosubgrouping command. ############################################################### # Build related options ############################################################### EXTRACT_ALL = NO # If the EXTRACT_ALL tag is set to YES doxygen will assume all entities in documentation are documented, even if no documentation was available.

When set to YES local methods, which are defined in the implementation section but not in the interface are included in the documentation. If set to NO (the default) only methods in the interface are included. HIDE_UNDOC_MEMBERS = NO # If the HIDE_UNDOC_MEMBERS tag is set to YES, doxygen will hide all undocumented members inside documented classes or files. If set to NO (the default) these members will be included in the various overviews, but no documentation section is generated. This option has no effect if EXTRACT_ALL is enabled. HIDE_UNDOC_CLASSES = NO # If the HIDE_UNDOC_CLASSESS tag is set to YES, doxygen will hide all undocumented classes. If set to NO (the default) these classes will be included in the various overviews. This option has no effect if EXTRACT_ALL is enabled. HIDE_FRIEND_COMPOUNDS = NO # If the HIDE_FRIEND_COMPOUNDS tag is set to YES, Doxygen will hide all friend (class|struct|union) declarations. If set to NO (the default) these declarations will be included in the documentation. # HIDE_IN_BODY_DOCS = # If the HIDE_IN_BODY_DOCS tag is set to YES, Doxygen will hide any documentation blocks found inside the body of a function. If set to NO (the default) these blocks will be appended to the function's detailed documentation block. # INTERNAL_DOCS = # The INTERNAL_DOCS tag determines if documentation that is typed after a \internal command is included. If the tag is set to NO (the default) then the documentation will be excluded. Set it to YES to include the internal documentation.

If set to NO the members will appear in declaration order. # SORT_BRIEF_DOCS = # If the SORT_BRIEF_DOCS tag is set to YES then doxygen will sort the brief descriptions of file, namespace and class members alphabetically by member name. If set to NO (the default) the members will appear in declaration order. # GENERATE_DEPRECATEDLIST = # The GENERATE_DEPRECATEDLIST tag can be used to enable (YES) or disable (NO) the deprecated list.

If the initializer consists of more lines than specified here it will be hidden. Use a value of 0 to hide initializers completely. The appearance of the value of individual variables and defines can be controlled using \showinitializer or \hideinitializer command in the documentation. SHOW_USED_FILES = YES # Set the SHOW_USED_FILES tag to NO to disable the list of files generated at the bottom of the documentation of classes and structs. If set to YES the list will mention the files that were used to generate the documentation. SHOW_DIRECTORIES = NO # If the sources in your project are distributed over multiple directories then setting the SHOW_DIRECTORIES tag to YES will show the directory hierarchy in the documentation. ############################################################### # Options related to warning and progress messages ############################################################### QUIET = YES # The QUIET tag can be used to turn on/off the messages that are generated to standard output by doxygen. Possible values are YES and NO, where YES implies that the messages are off. If left blank NO is used. # WARNINGS = # The WARNINGS tag can be used to turn on/off the warning messages that are generated to standard error by doxygen. Possible values are YES and NO, where YES implies that the warnings are on. If left blank NO is used. # # Tip: Turn warnings on while writing the documentation. WARN_IF_UNDOCUMENTED = YES # If WARN_IF_UNDOCUMENTED is set to YES, then doxygen will generate warnings for undocumented members. If EXTRACT_ALL is set to YES then this flag will automatically be disabled.

WARN_NO_PARAMDOC = YES # This WARN_NO_PARAMDOC option can be abled to get warnings for functions that are documented, but have no documentation for their parameters or return value. If set to NO (the default) doxygen will only warn about wrong or incomplete parameter documentation, but not about the absence of documentation. WARN_FORMAT = "WARNING: $text ($line, $file)" # The WARN_FORMAT tag determines the format of the warning messages that doxygen can produce. The string should contain the $file, $line, and $text tags, which will be replaced by the file and line number from which the warning originated and the warning text. # WARN_LOGFILE = # The WARN_LOGFILE tag can be used to specify a file to which warning and error messages should be written. If left blank the output is written to stderr. ############################################################### # Input related options ############################################################### INPUT = ../include Mainpage # The INPUT tag is used to specify the files and/or directories that contain documented source files. You may enter file names like myfile.cpp or directories like /usr/src/myproject. Separate the files or directories with spaces. # # Note: If this tag is empty the current directory is searched. # FILE_PATTERNS = # If the value of the INPUT tag contains directories, you can use the FILE_PATTERNS tag to specify one or more wildcard patterns (like *.cpp and *.h ) to filter out the source-files in the directories. If left blank the following patterns are tested: .c *.cc *.cxx *.cpp *.c++ *.java *.ii *.ixx *.ipp *.i++ *.inl *.h *.hh *.hxx *.hpp .h++ *.idl *.odl *.cs *.php *.php3 *.inc *.m *.mm # FILE_VERSION_FILTER = # The FILE_VERSION_FILTER tag can be used to specify a program or script that doxygen should invoke to get the current version for each file (typically from the version control system). Doxygen will invoke the program by executing (via popen()) the command command input-file, where command is the value of the FILE_VERSION_FILTER tag, and input-file is the name of an input file provided by doxygen. Whatever the program writes to standard output is used as the file version. # # Example of using a shell script as a filter for Unix: # # FILE_VERSION_FILTER = "/bin/sh versionfilter.sh" # # Example shell script for CVS: # # #!/bin/sh # cvs status $1 | sed -n 's/^[ \]*Working revision:[ \t]*\([0-9][0-9\.]*\).*/\1/p' # # Example shell script for Subversion: # # #!/bin/sh # svn stat -v $1 | sed -n 's/^[ A-Z?\*|!]\{1,15\}/r/;s/ \{1,15\}/\/r/;s/ .*//p' # # Example filter for ClearCase: # # FILE_VERSION_INFO = "cleartool desc -fmt \%Vn" RECURSIVE = YES # The RECURSIVE tag can be used to specify whether or not subdirectories should be searched for input files as well. Possible values are YES and NO. If left blank NO is used. # EXCLUDE = # The EXCLUDE tag can be used to specify files and/or directories that should excluded from the INPUT source files. This way you can easily exclude a subdirectory from a directory tree whose root is specified with the INPUT tag. # EXCLUDE_SYMLINKS = # The EXCLUDE_SYMLINKS tag can be used select whether or not files or directories that are symbolic links (a Unix filesystem feature) are excluded from the input. # EXCLUDE_PATTERNS = # If the value of the INPUT tag contains directories, you can use the EXCLUDE_PATTERNS tag to specify one or more wildcard patterns to exclude certain files from those directories. # Note that the wildcards are matched against the file with absolute path, so to exclude all test directories use the pattern */test/* # EXAMPLE_PATH = # The EXAMPLE_PATH tag can be used to specify one or more files or directories that contain example code fragments that are included (see the \include command in section \include). # EXAMPLE_RECURSIVE = # If the EXAMPLE_RECURSIVE tag is set to YES then subdirectories will be searched for input files to be used with the \include or \dontinclude commands irrespective of the value of the RECURSIVE tag. Possible values are YES and NO. If left blank NO is used. # EXAMPLE_PATTERNS = # If the value of the EXAMPLE_PATH tag contains directories, you can use the EXAMPLE_PATTERNS tag to specify one or more wildcard pattern (like *.cpp and *.h) to filter out the source-files in the directories. If left blank all files are included. # IMAGE_PATH = # The IMAGE_PATH tag can be used to specify one or more files or directories that contain images that are to be included in the documentation (see the \image command). INPUT_FILTER = "bash preprocess.sh" # The INPUT_FILTER tag can be used to specify a program that doxygen should invoke to filter for each input file. Doxygen will invoke the filter program by executing (via popen()) the command: # # # # where is the value of the INPUT_FILTER tag, and is the name of an input file. Doxygen will then use the output that the filter program writes to standard output. # FILTER_PATTERNS = # The FILTER_PATTERNS tag can be used to specify filters on a per file pattern basis. Doxygen will compare the file name with each pattern and apply the filter if there is a match. The filters are a list of the form: pattern=filter (like *.cpp=my_cpp_filter). See INPUT_FILTER for further info on how filters are used. If FILTER_PATTERNS is empty, INPUT_FILTER is applied to all files. # FILTER_SOURCE_FILES = # If the FILTER_SOURCE_FILES tag is set to YES, the input filter (if set using INPUT_FILTER ) will also be used to filter the input files that are used for producing the source files to browse (i.e. when SOURCE_BROWSER is set to YES). ############################################################### # Source browsing related options ############################################################### # SOURCE_BROWSER = # If the SOURCE_BROWSER tag is set to YES then a list of source files will be generated. Documented entities will be cross-referenced with these sources. # INLINE_SOURCES = # Setting the INLINE_SOURCES tag to YES will include the body of functions, classes and enums directly into the documentation. STRIP_CODE_COMMENTS = YES # Setting the STRIP_CODE_COMMENTS tag to YES (the default) will instruct doxygen to hide any special comment blocks from generated source code fragments. Normal C and C++ comments will always remain visible. # REFERENCED_BY_RELATION = # If the REFERENCED_BY_RELATION tag is set to YES (the default) then for each documented function all documented functions referencing it will be listed. # REFERENCES_RELATION = # If the REFERENCES_RELATION tag is set to YES (the default) then for each documented function all documented entities called/used by that function will be listed. # REFERENCES_LINK_SOURCE = # If the REFERENCES_LINK_SOURCE tag is set to YES (the default) and SOURCE_BROWSER tag is set to YES, then the hyperlinks from functions in REFERENCES_RELATION and REFERENCED_BY_RELATION lists will link to the source code. Otherwise they will link to the documentstion. VERBATIM_HEADERS = NO # If the VERBATIM_HEADERS tag is set the YES (the default) then doxygen will generate a verbatim copy of the header file for each class for which an include is specified. Set to NO to disable this. # # See also: # Section \class. # USE_HTAGS = # If the USE_HTAGS tag is set to YES then the references to source code will point to the HTML generated by the htags(1) tool instead of doxygen built-in source browser. The htags tool is part of GNU's global source tagging system (see http://www.gnu.org/software/global/global.html). The use it do the following: # # 1. Install the latest version of global (i.e. 4.8.6 or better) # 2. Enable SOURCE_BROWSER and USE_HTAGS in the config file # 3. Make sure the INPUT points to the root of the source tree # 4. Run doxygen as normal # # Doxygen will invoke htags (and that will in turn invoke gtags), so these tools must be available from the command line (i.e. in the search path). # # The result: instead of the source browser generated by doxygen, the links to source code will now point to the output of htags. ############################################################### # Alphabetical index options ############################################################### # COLS_IN_ALPHA_INDEX = # If the alphabetical index is enabled (see ALPHABETICAL_INDEX) then the COLS_IN_ALPHA_INDEX tag can be used to specify the number of columns in which this list will be split (can be a number in the range [1..20]) # IGNORE_PREFIX = # In case all classes in a project start with a common prefix, all classes will be put under the same header in the alphabetical index. The IGNORE_PREFIX tag can be used to specify a prefix (or a list of prefixes) that should be ignored while generating the index headers. ############################################################### # HTML related options ############################################################### GENERATE_HTML = YES # If the GENERATE_HTML tag is set to YES (the default) doxygen will generate HTML output # HTML_OUTPUT = TODO # The HTML_OUTPUT tag is used to specify where the HTML docs will be put. If a relative path is entered the value of OUTPUT_DIRECTORY will be put in front of it. If left blank `html' will be used as the default path. # HTML_FILE_EXTENSION = # The HTML_FILE_EXTENSION tag can be used to specify the file extension for each generated HTML page (for example: .htm, .php, .asp). If it is left blank doxygen will generate files with .html extension. # HTML_HEADER = TODO # The HTML_HEADER tag can be used to specify a user-defined HTML header file for each generated HTML page. To get valid HTML the header file should contain at least a and a tag, but it is good idea to include the style sheet that is generated by doxygen as well. Minimal example: # # # # My title # # # # # If the tag is left blank doxygen will generate a standard header. # # The following commands have a special meaning inside the header: $title, $datetime, $date, $doxygenversion, $projectname, and $projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see PROJECT_NAME), or the project number (see PROJECT_NUMBER). # # If CREATE_SUBDIRS is enabled, the command $relpath$ can be used to produce a relative path to the root of the HTML output directory, e.g. use $relpath$doxygen.css, to refer to the standard style sheet. # # See also section Doxygen usage for information on how to generate the default header that doxygen normally uses. # HTML_FOOTER = # The HTML_FOOTER tag can be used to specify a user-defined HTML footer for each generated HTML page. To get valid HTML the footer file should contain at least a and a tag. A minimal example: # # # # # If the tag is left blank doxygen will generate a standard footer. # # The following commands have a special meaning inside the footer: $title, $datetime, $date, $doxygenversion, $projectname, $projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see PROJECT_NAME), or the project number (see PROJECT_NUMBER). # # See also section Doxygen usage for information on how to generate the default footer that doxygen normally uses. # HTML_STYLESHEET = # The HTML_STYLESHEET tag can be used to specify a user-defined cascading style sheet that is used by each HTML page. It can be used to fine-tune the look of the HTML output. If the tag is left blank doxygen will generate a default style sheet. # # See also section Doxygen usage for information on how to generate the style sheet that doxygen normally uses. # HTML_ALIGN_MEMBERS = # If the HTML_ALIGN_MEMBERS tag is set to YES, the members of classes, files or namespaces will be aligned in HTML using tables. If set to NO a bullet list will be used. # # Note: Setting this tag to NO will become obsolete in the future, since I only intent to support and test the aligned representation. GENERATE_HTMLHELP = @GENERATE_HTMLHELP@ # If the GENERATE_HTMLHELP tag is set to YES then doxygen generates three additional HTML index files: index.hhp, index.hhc, and index.hhk. The index.hhp is a project file that can be read by Microsoft's HTML Help Workshop on Windows. # # The HTML Help Workshop contains a compiler that can convert all HTML output generated by doxygen into a single compressed HTML file (.chm). Compressed HTML files are now used as the Windows 98 help format, and will replace the old Windows help format (.hlp) on all Windows platforms in the future. Compressed HTML files also contain an index, a table of contents, and you can search for words in the documentation. The HTML workshop also contains a viewer for compressed HTML files. HHC_LOCATION = ../hhc.exe # If the GENERATE_HTMLHELP tag is set to YES, the HHC_LOCATION tag can be used to specify the location (absolute path including file name) of the HTML help compiler (hhc.exe). If non empty doxygen will try to run the HTML help compiler on the generated index.hhp. # GENERATE_CHI = # If the GENERATE_HTMLHELP tag is set to YES, the GENERATE_CHI flag controls if a separate .chi index file is generated (YES) or that it should be included in the master .chm file (NO). # BINARY_TOC = # If the GENERATE_HTMLHELP tag is set to YES, the BINARY_TOC flag controls whether a binary table of contents is generated (YES) or a normal table of contents (NO) in the .chm file. # TOC_EXPAND = # The TOC_EXPAND flag can be set to YES to add extra items for group members to the table of contents of the HTML help documentation and to the tree view. # DISABLE_INDEX = # If you want full control over the layout of the generated HTML pages it might be necessary to disable the index and replace it with your own. The DISABLE_INDEX tag can be used to turn on/off the condensed index at top of each page. A value of NO (the default) enables the index and the value YES disables it. # ENUM_VALUES_PER_LINE = # This tag can be used to set the number of enum values (range [1..20]) that doxygen will group on one line in the generated HTML documentation. # GENERATE_TREEVIEW = # If the GENERATE_TREEVIEW tag is set to YES, a side panel will be generated containing a tree-like index structure (just like the one that is generated for HTML Help). For this to work a browser that supports JavaScript and frames is required (for instance Mozilla 1.0+, Netscape 6.0+ or Internet explorer 5.0+ or Konqueror). # TREEVIEW_WIDTH = # If the treeview is enabled (see GENERATE_TREEVIEW) then this tag can be used to set the initial width (in pixels) of the frame in which the tree is shown. ############################################################### # LaTeX related options ############################################################### GENERATE_LATEX = NO # If the GENERATE_LATEX tag is set to YES (the default) doxygen will generate $\mbox{\LaTeX}$ output. # LATEX_OUTPUT = # The LATEX_OUTPUT tag is used to specify where the $\mbox{\LaTeX}$ docs will be put.

If left blank `latex' will be used as the default command name. # MAKEINDEX_CMD_NAME = # The MAKEINDEX_CMD_NAME tag can be used to specify the command name to generate index for LaTeX. If left blank `makeindex' will be used as the default command name. # COMPACT_LATEX = # If the COMPACT_LATEX tag is set to YES doxygen generates more compact $\mbox{\LaTeX}$ documents. This may be useful for small projects and may help to save some trees in general. # PAPER_TYPE = # The PAPER_TYPE tag can be used to set the paper type that is used by the printer. Possible values are: # # * a4 (210 x 297 mm). # * a4wide (same as a4, but including the a4wide package). # * letter (8.5 x 11 inches). # * legal (8.5 x 14 inches). # * executive (7.25 x 10.5 inches) # # If left blank a4wide will be used. # EXTRA_PACKAGES = # The EXTRA_PACKAGES tag can be used to specify one or more $\mbox{\LaTeX}$ package names that should be included in the $\mbox{\LaTeX}$ output. To get the times font for instance you can specify # # EXTRA_PACKAGES = times # # If left blank no extra packages will be included. # LATEX_HEADER = # The LATEX_HEADER tag can be used to specify a personal $\mbox{\LaTeX}$ header for the generated $\mbox{\LaTeX}$ document. The header should contain everything until the first chapter. # # If it is left blank doxygen will generate a standard header. See section Doxygen usage for information on how to let doxygen write the default header to a separate file. # # Note: # Only use a user-defined header if you know what you are doing! # # The following commands have a special meaning inside the header: $title, $datetime, $date, $doxygenversion, $projectname, $projectnumber. Doxygen will replace them by respectively the title of the page, the current date and time, only the current date, the version number of doxygen, the project name (see PROJECT_NAME), or the project number (see PROJECT_NUMBER). # PDF_HYPERLINKS = # If the PDF_HYPERLINKS tag is set to YES, the $\mbox{\LaTeX}$ that is generated is prepared for conversion to PDF (using ps2pdf or pdflatex). The PDF file will contain links (just like the HTML output) instead of page references. This makes the output suitable for online browsing using a PDF viewer. # USE_PDFLATEX = # If the LATEX_PDFLATEX tag is set to YES, doxygen will use pdflatex to generate the PDF file directly from the $\mbox{\LaTeX}$ files. # LATEX_BATCHMODE = # If the LATEX_BATCHMODE tag is set to YES, doxygen will add the \batchmode. command to the generated $\mbox{\LaTeX}$ files. This will instruct $\mbox{\LaTeX}$ to keep running if errors occur, instead of asking the user for help. This option is also used when generating formulas in HTML. # LATEX_HIDE_INDICES = # If LATEX_HIDE_INDICES is set to YES then doxygen will not include the index chapters (such as File Index, Compound Index, etc.) in the output. ############################################################### # RTF related options ############################################################### # GENERATE_RTF = # If the GENERATE_RTF tag is set to YES doxygen will generate RTF output. The RTF output is optimized for Word 97 and may not look too pretty with other readers/editors. # RTF_OUTPUT = # The RTF_OUTPUT tag is used to specify where the RTF docs will be put. If a relative path is entered the value of OUTPUT_DIRECTORY will be put in front of it. If left blank rtf will be used as the default path. # COMPACT_RTF = # If the COMPACT_RTF tag is set to YES doxygen generates more compact RTF documents. This may be useful for small projects and may help to save some trees in general. # RTF_HYPERLINKS = # If the RTF_HYPERLINKS tag is set to YES, the RTF that is generated will contain hyperlink fields. The RTF file will contain links (just like the HTML output) instead of page references. This makes the output suitable for online browsing using Word or some other Word compatible reader that support those fields. # # note: # WordPad (write) and others do not support links. # RTF_STYLESHEET_FILE = # Load stylesheet definitions from file. Syntax is similar to doxygen's config file, i.e. a series of assignments. You only have to provide replacements, missing definitions are set to their default value. # # See also section Doxygen usage for information on how to generate the default style sheet that doxygen normally uses. # RTF_EXTENSIONS_FILE = # Set optional variables used in the generation of an RTF document. Syntax is similar to doxygen's config file. A template extensions file can be generated using doxygen -e rtf extensionFile. ############################################################### # Man page related options ############################################################### # GENERATE_MAN = # If the GENERATE_MAN tag is set to YES (the default) doxygen will generate man pages for classes and files. # MAN_OUTPUT = # The MAN_OUTPUT tag is used to specify where the man pages will be put. If a relative path is entered the value of OUTPUT_DIRECTORY will be put in front of it. If left blank `man' will be used as the default path. A directory man3 will be created inside the directory specified by MAN_OUTPUT. # MAN_EXTENSION = # The MAN_EXTENSION tag determines the extension that is added to the generated man pages (default is the subroutine's section .3) # MAN_LINKS = # If the MAN_LINKS tag is set to YES and doxygen generates man output, then it will generate one additional man file for each entity documented in the real man page(s).

Note that this feature is still experimental and incomplete at the moment. # PERLMOD_LATEX = # If the PERLMOD_LATEX tag is set to YES Doxygen will generate the necessary Makefile rules, Perl scripts and LaTeX code to be able to generate PDF and DVI output from the Perl module output. # PERLMOD_PRETTY = # If the PERLMOD_PRETTY tag is set to YES the Perl module output will be nicely formatted so it can be parsed by a human reader. This is useful if you want to understand what is going on. On the other hand, if this tag is set to NO the size of the Perl module output will be much smaller and Perl will parse it just the same. # PERLMOD_MAKEVAR_PREFIX = # The names of the make variables in the generated doxyrules.make file are prefixed with the string contained in PERLMOD_MAKEVAR_PREFIX. This is useful so different doxyrules.make files included by the same Makefile don't overwrite each other's variables. ############################################################### # Preprocessor related options ############################################################### ENABLE_PREPROCESSING = YES # If the ENABLE_PREPROCESSING tag is set to YES (the default) doxygen will evaluate all C-preprocessor directives found in the sources and include files. MACRO_EXPANSION = NO # If the MACRO_EXPANSION tag is set to YES doxygen will expand all macro names in the source code. If set to NO (the default) only conditional compilation will be performed. Macro expansion can be done in a controlled way by setting EXPAND_ONLY_PREDEF to YES. EXPAND_ONLY_PREDEF = NO # If the EXPAND_ONLY_PREDEF and MACRO_EXPANSION tags are both set to YES then the macro expansion is limited to the macros specified with the PREDEFINED and EXPAND_AS_DEFINED tags. SEARCH_INCLUDES = YES # If the SEARCH_INCLUDES tag is set to YES (the default) the includes files in the INCLUDE_PATH (see below) will be searched if a #include is found. INCLUDE_PATH = ../include # The INCLUDE_PATH tag can be used to specify one or more directories that contain include files that are not input files but should be processed by the preprocessor. # PREDEFINED = # The PREDEFINED tag can be used to specify one or more macro names that are defined before the preprocessor is started (similar to the -D option of gcc). The argument of the tag is a list of macros of the form: name or name=definition (no spaces). If the definition and the "=" are omitted, "=1" is assumed. To prevent a macro definition from being undefined via #undef or recursively expanded use the := operator instead of the = operator. # EXPAND_AS_DEFINED = # If the MACRO_EXPANSION and EXPAND_ONLY_PREDEF tags are set to YES then this tag can be used to specify a list of macro names that should be expanded. The macro definition that is found in the sources will be used. Use the PREDEFINED tag if you want to use a different macro definition. # SKIP_FUNCTION_MACROS = # If the SKIP_FUNCTION_MACROS tag is set to YES (the default) then doxygen's preprocessor will remove all function-like macros that are alone on a line, have an all uppercase name, and do not end with a semicolon. Such function macros are typically used for boiler-plate code, and will confuse the parser if not removed. ############################################################### # External reference options ############################################################### # TAGFILES = # The TAGFILES tag can be used to specify one or more tagfiles. # # See section Doxytag usage for more information about the usage of tag files. # # Optionally an initial location of the external documentation can be added for each tagfile. The format of a tag file without this location is as follows: # # TAGFILES = file1 file2 ... # # Adding location for the tag files is done as follows: # # TAGFILES = file1=loc1 "file2 = loc2" ... # # where loc1 and loc2 can be relative or absolute paths or URLs, If a location is present for each tag, the installdox tool (see section Installdox usage for more information) does not have to be run to correct the links. # # Note: # Each tag file must have a unique name (where the name does not include the path) If a tag file is not located in the directory in which doxygen is run, you must also specify the path to the tagfile here. # GENERATE_TAGFILE = # When a file name is specified after GENERATE_TAGFILE, doxygen will create a tag file that is based on the input files it reads. See section Doxytag usage for more information about the usage of tag files. # ALLEXTERNALS = # If the ALLEXTERNALS tag is set to YES all external class will be listed in the class index. If set to NO only the inherited external classes will be listed. # EXTERNAL_GROUPS = # If the EXTERNAL_GROUPS tag is set to YES all external groups will be listed in the modules index. If set to NO, only the current project's groups will be listed. # PERL_PATH = # The PERL_PATH should be the absolute path and name of the perl script interpreter (i.e. the result of `which perl'). ############################################################### # Dot options ############################################################### # CLASS_DIAGRAMS = # If the CLASS_DIAGRAMS tag is set to YES (the default) doxygen will generate a class diagram (in HTML and $\mbox{\LaTeX}$) for classes with base or super classes. Setting the tag to NO turns the diagrams off. Note that this option is superseded by the HAVE_DOT option below. This is only a fallback. It is recommended to install and use dot, since it yields more powerful graphs. HAVE_DOT = YES # If you set the HAVE_DOT tag to YES then doxygen will assume the dot tool is available from the path. This tool is part of Graphviz, a graph visualization toolkit from AT&T and Lucent Bell Labs. The other options in this section have no effect if this option is set to NO (the default) CLASS_GRAPH = NO # If the CLASS_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented class showing the direct and indirect inheritance relations. Setting this tag to YES will force the the CLASS_DIAGRAMS tag to NO. COLLABORATION_GRAPH = NO # If the COLLABORATION_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented class showing the direct and indirect implementation dependencies (inheritance, containment, and class references variables) of the class with other documented classes. # GROUP_GRAPHS # If the GROUP_GRAPHS and HAVE_DOT tags are set to YES then doxygen will generate a graph for groups, showing the direct groups dependencies. UML_LOOK = NO # If the UML_LOOK tag is set to YES doxygen will generate inheritance and collaboration diagrams in a style similar to the OMG's Unified Modeling Language. # TEMPLATE_RELATIONS = # If the TEMPLATE_RELATIONS and HAVE_DOT tags are set to YES then doxygen will show the relations between templates and their instances. HIDE_UNDOC_RELATIONS = NO # If set to YES, the inheritance and collaboration graphs will hide inheritance and usage relations if the target is undocumented or is not a class. INCLUDE_GRAPH = YES # If the ENABLE_PREPROCESSING, SEARCH_INCLUDES, INCLUDE_GRAPH, and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented file showing the direct and indirect include dependencies of the file with other documented files. INCLUDED_BY_GRAPH = YES # If the ENABLE_PREPROCESSING, SEARCH_INCLUDES, INCLUDED_BY_GRAPH, and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented header file showing the documented files that directly or indirectly include this file. CALL_GRAPH = NO # If the CALL_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a call dependency graph for every global function or class method. Note that enabling this option will significantly increase the time of a run. So in most cases it will be better to enable call graphs for selected functions only using the \callgraph command. CALLER_GRAPH = NO # If the CALLER_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a caller dependency graph for every global function or class method. Note that enabling this option will significantly increase the time of a run. So in most cases it will be better to enable caller graphs for selected functions only using the \callergraph command. GRAPHICAL_HIERARCHY = YES # If the GRAPHICAL_HIERARCHY and HAVE_DOT tags are set to YES then doxygen will graphical hierarchy of all classes instead of a textual one. # DIRECTORY_GRAPH # If the DIRECTORY_GRAPH, SHOW_DIRECTORIES and HAVE_DOT options are set to YES then doxygen will show the dependencies a directory has on other directories in a graphical way. The dependency relations are determined by the #include relations between the files in the directories. # DOT_IMAGE_FORMAT = # The DOT_IMAGE_FORMAT tag can be used to set the image format of the images generated by dot. Possible values are gif, jpg, and png. If left blank png will be used. # DOT_PATH = # This tag can be used to specify the path where the dot tool can be found. If left blank, it is assumed the dot tool can be found on the path. # DOTFILE_DIRS = # This tag can be used to specify one or more directories that contain dot files that are included in the documentation (see the \dotfile command). # MAX_DOT_GRAPH_HEIGHT = # The MAX_DOT_GRAPH_HEIGHT tag can be used to set the maximum allows height (in pixels) of the graphs generated by dot. If a graph becomes larger than this value, doxygen will try to truncate the graph, so that it fits within the specified constraint. Beware that most browsers cannot cope with very large images. # MAX_DOT_GRAPH_DEPTH = # The MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the graphs generated by dot. A depth value of 3 means that only nodes reachable from the root by following a path via at most 3 edges will be shown. Nodes that lay further from the root node will be omitted. Note that setting this option to 1 or 2 may greatly reduce the computation time needed for large code bases. Also note that a graph may be further truncated if the graph's image dimensions are not sufficient to fit the graph (see MAX_DOT_GRAPH_WIDTH and MAX_DOT_GRAPH_HEIGHT). If 0 is used for the depth value (the default), the graph is not depth-constraint. # MAX_DOT_GRAPH_WIDTH = # The MAX_DOT_GRAPH_WIDTH tag can be used to set the maximum allowed width (in pixels) of the graphs generated by dot. If a graph becomes larger than this value, doxygen will try to truncate the graph, so that it fits within the specified constraint. Beware that most browsers cannot cope with very large images. # DOT_TRANSPARENT = # Set the DOT_TRANSPARENT tag to YES to generate images with a transparent background. This is disabled by default, which results in a white background. Warning: Depending on the platform used, enabling this option may lead to badly anti-aliased labels on the edges of a graph (i.e. they become hard to read). DOT_MULTI_TARGETS = YES # Set the DOT_MULTI_TARGETS tag to YES allow dot to generate multiple output files in one run (i.e. multiple -o and -T options on the command line). This makes dot run faster, but since only newer versions of dot (>1.8.10) support this, this feature is disabled by default. GENERATE_LEGEND = YES # If the GENERATE_LEGEND tag is set to YES (the default) doxygen will generate a legend page explaining the meaning of the various boxes and arrows in the dot generated graphs. # DOT_CLEANUP = # If the DOT_CLEANUP tag is set to YES (the default) doxygen will remove the intermediate dot files that are used to generate the various graphs. ############################################################### # Search engine options ############################################################### # SEARCHENGINE = # The SEARCHENGINE tag specifies whether or not the HTML output should contain a search facility. Possible values are YES and NO. If set to YES, doxygen will produce a search index and a PHP script to search through the index. For this to work the documentation should be viewed via a web-server running PHP version 4.1.0 or higher.

The following components of LINK-COMMAND are treated specially: -all-static do not do any dynamic linking at all -avoid-version do not add a version suffix if possible -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3) -export-symbols SYMFILE try to export only the symbols listed in SYMFILE -export-symbols-regex REGEX try to export only the symbols matching REGEX -LLIBDIR search LIBDIR for required installed libraries -lNAME OUTPUT-FILE requires the installed library libNAME -module build a library that can dlopened -no-fast-install disable the fast-install mode -no-install link a not-installable executable -no-undefined declare that a library does not refer to external symbols -o OUTPUT-FILE create OUTPUT-FILE from the specified objects -objectlist FILE Use a list of object files found in FILE to specify objects -precious-files-regex REGEX don't remove output files matching REGEX -release RELEASE specify package release information -rpath LIBDIR the created library will eventually be installed in LIBDIR -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries -static do not do any dynamic linking of uninstalled libtool libraries -static-libtool-libs do not do any dynamic linking of libtool libraries -version-info CURRENT[:REVISION[:AGE]] specify library version info [each variable defaults to 0] All other options (arguments beginning with \`-') are ignored. Every other argument is treated as a filename. Files ending in \`.la' are treated as uninstalled libtool libraries, other files are standard or library object files. If the OUTPUT-FILE ends in \`.la', then a libtool library is created, only library objects (\`.lo' files) may be specified, and \`-rpath' is required, except when creating a convenience library. If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created using \`ar' and \`ranlib', or on Windows using \`lib'. If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file is created, otherwise an executable program is created." ;; uninstall) $echo \ "Usage: $modename [OPTION]... --mode=uninstall RM [RM-OPTION]...

(#2418192). Thanks to Harvey Vrsalovic for reporting! * Fixed: Memory leak in uriFreeQueryList function (#2413066) Thanks to Daniel Chapiesky for reporting! * Fixed: Memory leak in uriNormalizeSyntax(Ex) functions (#2413066) Thanks to Daniel Chapiesky for reporting! * Improved: Nested configure hacks resolved * Soname: 1:9:0 2008-11-08 -- 0.7.3 * Fixed: Missing NULL check in parsing routines Thanks to Sezai Tekin for reporting! * Fixed: uriparser now builds on Cygwin * Fixed: Now shipping gnulib's config.guess from HEAD which is suitable for Haiku (#2116355) * Changed: swprintf requirement resolved * Changed: Build system changes: - configure option --enable-doc added - configure.in renamed to configure.ac - some Autotools files moved to build-aux directory * Added: Qt Assistant documentation output: - Qt Compressed Help (.qch) at - Qt Help Project (.qhp) at Generation requires Doxygen 1.5.7.1-20081103 or later. * Soname: 1:8:0 2008-09-01 -- 0.7.2 * Fixed: Bad cleanup logic in functions - uriAddBaseUri(..) - uriRemoveBaseUri(..) Previously you needed to call uriFreeUriMembers on return code URI_ERROR_MALLOC and only then. So that's why these functions now take cleanup off your shoulders. An extra call to uriFreeUriMembers from your side is still needed in case of success. * Soname: 1:7:0 2008-04-27 -- 0.7.1 * Fixed: Bogus syntax error when parsing URIs with port-like passwords, e.g. "http://user:21@host/" (#1948038) Thanks to Friedrich Delgado Friedrichs for reporting! * Fixed: Parser did not handle trailing slashes correctly in some cases, which also made the structures produced from parsing "http://e.com/" and "http://e.com" indistinguishable. (#1950126) Thanks to Edward Z. Yang for reporting! 2008-04-04 -- 0.7.0 * Added: Dissection and composition of query strings * Added: Documentation improvements (in|out|inout indicators, addition of \since and \see) * Changed: Code::Blocks project files updated from file format version 1.4 to 1.6, which is produced by Code::Blocks 8.02 * Added: Code::Blocks workspace file * Soname: 1:5:0 2008-02-25 -- 0.6.4 * Added: Syntax-based normalization can now handle relative URIs, e.g. "../../a/b/.././c" is normalized to "../../a/c" * Fixed: Normalization code could free foreign memory * Fixed: Normalization processed the path segment even when asked not to * Added: MinGW Makefile and related readme Thanks to Michael Anthony Puls II! * Fixed: Documentation bug not requiring enough memory for the output buffer when converting a relative file URI back to a filename * Soname: 1:4:0 2008-02-11 -- 0.6.3 * Fixed: Two major crash bugs in normalization code Thanks to Adrian Manrique for the patch! * Added: Brief usage tutorial * Soname: 1:3:0 2008-02-08 -- 0.6.2 * Fixed: Freeing a normalized URI like "http://test?" caused a crash. Thanks to Adrian Manrique for reporting! * Fixed: Filename <--> URI string conversion helpers can now handle relative URIs and filenames * Soname: 1:2:0 2007-12-23 -- 0.6.1 * Fixed: Percent-encodings in hostnames were not repaired during normalization. Thanks to Adrian Manrique for reporting! * Fixed: Percent-encodings were fixed after dot removal not before during normalization. Thanks to Adrian Manrique for reporting! * Fixed: Include path order bug Thanks to Ed Schouten for reporting this! * Fixed: Shadow builds now possible Thanks to Adeodato Simó for the patch! * Added: Version guards for Autoconf/Automake Thanks to Martin Michlmayr for reporting! * Soname: 1:1:0 2007-09-17 -- 0.6.0 * Fixed: Proper soname updates from now on, starting at 1:0:0 * Removed: Visual Studio 2003 project files 2007-09-13 -- 0.5.2 * Added: RemoveBaseUri function to create URI references * Added: Unix/Windows filename <--> URI string conversion helpers * Added: EscapeEx function to escape text blocks without zero termination * Fixed: Bug in ToString for URIs with scheme, path, but no host (e.g. "f:/.//g") * Fixed: AddBase now resolves ".//g" with base "f:/a" to "f:/.//g" instead of "f://g" which would result in "g" becoming the authority part when parsing a recomposition (ToString) of that URI structure. This is a whole in RFC 3986, see http://lists.w3.org/Archives/Public/uri/2007Aug/0003.html for details. 2007-08-09 -- 0.5.1 * Fixed: Empty host bug (URIs like "///g") * Fixed: Relative URIs are no longer touched by normalization * Fixed: MergePath failed for empty paths * Fixed: Bug with "." segments in AddBase All of the above revealed by test cases from 4Suite (http://4suite.org/) 2007-07-28 -- 0.5.0 * Added: Syntax-based normalization * Added: Percent-encoding function Escape * Improved: Malloc/NULL checks added * Added: New function UnescapeInPlaceEx can also decode '+' to ' ' and convert line breaks * Added: Exact space computation for ToString, see ToStringCharsRequired * Added: --enable-sizedown for saving space and slower code * Fixed: Two internal functions were exposed in the API by mistake: uriPushToStack and uriStackToOctet * Added: Visual Studio 2005 project files * Removed: Legacy code (removal was announced for 0.5.0) 2007-07-06 -- 0.4.1 * Fixed: ToString did not work for IPv4 and IPv6 hosts 2007-07-03 -- 0.4.0 * Added: References resolution (think relative to absolute) * Added: Naive URI equality check * Added: URIs can now be converted back to strings * Fixed: The first path segment of a relative URI was eaten (functions ParseSegmentNz and ParseMustBeSegmentNzNc) * Fixed: uri->scheme.first was not reset in some cases (function ParseMustBeSegmentNzNc) * Improved: Test suite now built on "make check", not before * Fixed: Test suite always returned 0 (success) 2007-04-23 -- 0.3.4 * Added: Shared library support (moved to libtool) 2007-04-03 -- 0.3.3 * Fixed: Now unix EOLs constantly * Fixed: Added forgotten files to release package 2007-03-31 -- 0.3.2 * Fixed: Now compiles on FreeBSD 2007-03-28 -- 0.3.1 * Fixed: Now compiles on Mac OS X 2007-03-26 -- 0.3.0 * Added: New API, old marked deprecated * Added: Unicode support (think wchar_t) * Added: Doxygen code documentation * Added: Test suite using CppTest * Changed: Library code is now licensed under the new BSD license. The test suite code is licensed under LGPL. 2006-12-08 -- 0.2.1 uriparser-0.7.5/lib/0000777000175000017500000000000011153522522011310 500000000000000uriparser-0.7.5/lib/UriCompare.c0000644000175000017500000001220511123237377013446 00000000000000/* * uriparser - RFC 3986 URI parsing library * * Copyright (C) 2007, Weijia Song * Copyright (C) 2007, Sebastian Pipping * All rights reserved. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * * * Redistributions of source code must retain the above * copyright notice, this list of conditions and the following * disclaimer. * * * Redistributions in binary form must reproduce the above * copyright notice, this list of conditions and the following * disclaimer in the documentation and/or other materials * provided with the distribution. * * * Neither the name of the nor the names of its * contributors may be used to endorse or promote products * derived from this software without specific prior written * permission. * * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS * FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
