Uniform Resource Identifier - Wikipedia, the free encyclopedia A Uniform Resource Locator (URL) is a URI that, in addition to identifying a resource, provides a means of acting upon or obtaining a representation of the resource by describing its primary access mechanism or network "location". An optional fragment identifier, preceded by "#", may be present at the end of a URI reference. If a fragment identifier is present in the URI reference, it is preserved during the merging process. en.wikipedia.org /wiki/Uniform_Resource_Identifier   (1997 words)

Proposal for XML Fragment Identifier Syntax 0.9   (Site not responding. Last check: 2007-11-07) The semantics of a fragment identifier is a property of the data resulting from a retrieval action, regardless of the type of URI used in the reference. A fragment identifier is only meaningful when a URI reference is intended for retrieval and the result of that retrieval is a document for which the identified fragment is consistently defined. Given the widespread use of fragment identifiers and the scope of XPointers in particular and URI references in general, it is not a user requirement to be able to write “query-like” statements in the fragment identifier. www.w3.org /TR/2003/NOTE-xml-fragid-20030912   (1101 words)

On The Meaning of Fragment Identifiers Servers never see fragment identifiers, they are handled entirely by the client application after it retrieves the URI without the fragment identifier. [...] The semantics of a fragment identifier is a property of the data resulting from a retrieval action, regardless of the type of URI used in the reference. Therefore, the format and interpretation of fragment identifiers is dependent on the media type [RFC2046] of the retrieval result. norman.walsh.name /2003/08/08/octothorp   (468 words)

Fragment Identifiers -- Axioms of Web architecture   (Site not responding. Last check: 2007-11-07) The fragment identifier is a string after URI, after the hash, which identifies something specific as a function of the document. The fragment identifier on an RDF (or N3) document identifies not a part of the document, but whatever thing, abstract or concrete, animate or innanimate, the document describes as having that identifier. Clearly when a fragment ID is generated and associated with a URI which is generic in any way (language, version, etc as well as content-type), then there is a possible failure of the fragment-id refers to something which is not defined in any specific instance. www.w3.org /DesignIssues/Fragment.html   (1069 words)

Architecture of the World Wide Web, First Edition   (Site not responding. Last check: 2007-11-07) The interpretation of fragment identifiers is discussed in the section on media types and fragment identifier semantics. Fragment identifier semantics are orthogonal to URI schemes and thus cannot be redefined by URI scheme specifications. Parties that draw conclusions about the interpretation of a fragment identifier based solely on a syntactic analysis of all or part of a URI do so at their own risk; such interpretations are not authoritative because they are not licensed by specification (specifically [URI]). www.www.org /TR/2004/WD-webarch-20040705   (14766 words)

Uniform Resource Identifier (URI): Generic Syntax Fragment identifier semantics are independent of the URI scheme and thus cannot be redefined by scheme specifications. 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. gbiv.com /protocols/uri/rev-2002/rfc2396bis.html   (13703 words)

[No title]   (Site not responding. Last check: 2007-11-07) In the example, the fragment identifier is a single name, but again depending on the type of resource, it may be a complex expression. Bos [Page 2] draft Fragment IDs in redirected URLs 30 June 1999 But HTTP 1.1 doesn't talk explicitly about fragment identifiers, which has resulted in the sad fact that at the time of writing, there are clients that drop the fragment identifier upon a redirect. A suggestion for a future version of HTTP may be to add an (optional) Fragment header to the request, which holds the fragment identifier. www.w3c.org /Protocols/HTTP/Fragment/draft-bos-http-redirect-00.txt   (1118 words)

Fragment Identifier for XML (FIXptr) Because fragment identifier processing is such a basic part of XML on the Web and needs to be efficiently supportable on a wide range of devices and applications, this proposal suggests a small subset of XPointer functionality, called FIXptr, for this purpose. It is an error for a FIXptr fragment identifier to appear in a URI reference that specifies a resource that does not have an XML infoset. A fragment identifier language for XML data, just as for any Internet media type, is likelier to be widely deployed and interoperable if it requires a more modest investment of resources. lists.w3.org /Archives/Public/www-xml-linking-comments/2001AprJun/att-0074/01-NOTE-FIXptr-20010425.htm   (3762 words)

suggested replacement text "circle or spline" from Chris Lilley on 2002-08-30 (www-tag@w3.org from August ... The fragment identifier syntax of HTML is familiar to people on this list; it refers to a single element identified by the NAME attribute on an A element or (in more recent versions) identified by an id attribute of type ID on any element. I agree that there is a need to show other examples of fragment identifiers on other media types, to convey some of the richer possibilities, before ending that paragraph with the description of what RDF does with fragment identifiers. It follows therefore that a fragment identifier in a graphics format does not point to a geometric circle (for example, a circle drawn on the screen as a result of rendering an SVG circle element). lists.w3.org /Archives/Public/www-tag/2002Aug/0371.html   (983 words)

Architecture of the World Wide Web, First Edition   (Site not responding. Last check: 2007-11-07) Fragment identifier semantics are independent of the URI scheme and thus cannot be redefined by URI scheme specifications. Interpretation of the fragment identifier during a retrieval action is performed solely by the agent; the fragment identifier is not passed to other systems during the process of retrieval. Since the namespace is identified by the URI "http://weather.example.com/2003/format", she asks her browser to retrieve a representation of the namespace via that URI. www.w3c.org /2001/tag/2004/webarch-20040507   (13803 words)

An example HTML document Fragment Identifier When a URI reference is used to perform a retrieval action on the identified resource, the optional fragment identifier, separated from the URI by a crosshatch ("#") character, consists of additional reference information to be interpreted by the user agent after the retrieval action has been successfully completed. fragment = *uric The semantics of a fragment identifier is a property of the data resulting from a retrieval action, regardless of the type of URI used in the reference. In the case where a fragment identifier is associated with a URI reference, the fragment would be placed within the brackets as well (separated from the URI with a "#" character). www.ietf.org /rfc/rfc2396.txt?number=2396   (10148 words)

Amazon.com: Phrase: "fragment identifier"   (Site not responding. Last check: 2007-11-07) The value of the attribute is a URI that uses a fragment identifier to access the subdialog. The reporterld is concatenated onto the URI as a fragment identifier as described in a previous section, External Grammar Files. The theory is that the syntax of a URI fragment identifier depends on the media type of the resource identified by the URI. www.amazon.com /gp/phrase/ref=sip_bod_8/104-0406451-9975120?%5Fencoding=UTF8&src=0735605629&checkSum=aGTVnWU93ApEIbYK8t%2FHYIDzYrBSurnOthZm1cw8V3U%3D&phrase=fragment%20identifier   (4334 words)

2.4.1. Parsing the Fragment Identifier   (Site not responding. Last check: 2007-11-07) If the crosshatch is the last character, or no crosshatch is present, then the fragment identifier is empty. Note that the fragment identifier is not considered part of the URL. However, since it is often attached to the URL, parsers must be able to recognize and set aside fragment identifiers as part of the process. www.freesoft.org /CIE/RFC/1808/7.htm   (101 words)

fragment identifier - named anchor plus query string in one url In other words, according to the RCF the URL is split by the fragment identifier first (#), if present, and *then* parsed as an address. It's therefore imperative that the fragment identifier is placed last in the URL, which may also be combined with a query string as in: http://www.example.com/index.html?foo=barandhello=worldand#midpage does also work but has no bearing on the issue at hand, the last "and" is treated merely as an incomplete query string and discarded once the fragment identifier is separated from the URL during initial parsing of the URL. www.webmasterworld.com /forum21/8405.htm   (439 words)

RDF Pointer: The RDF fragment identifier syntax This paper proposes a fragment identifier syntax for the MIME media types: text/rdf+xml and application/rdf+xml. This syntax is intended to be compatible with and an extension of the fragment identifier syntax for text/xml and application/xml namely XPointer. When any of the predicate, subject or object parameters are blank, the triple fragment identifier may match a collection of statements. www.openhealth.org /RDF/RDFmediatype.html   (366 words)

Zvon - RFC 2396 [Uniform Resource Identifiers (URI): Generic Syntax] - URI References A URI reference may be absolute or relative, and may have additional information attached in the form of a fragment identifier. In other words, an empty URI reference within a document is interpreted as a reference to the start of that document, and a reference containing only a fragment identifier is a reference to the identified fragment of that document. A URI reference is typically parsed according to the four main components and fragment identifier in order to determine what components are present and whether the reference is relative or absolute. www.zvon.org /tmRFC/RFC2396/Output/chapter4.html   (645 words)

XML.com: Interacting with Resources: Web Architecture Review   (Site not responding. Last check: 2007-11-07) Given the utility of the opacity of web identifiers it stands to reason that the protocol by means of which interactions between user agents and servers is structured includes provisions for transmitting metadata about the format of the retrieved representation. Since only SVG defines a meaning for fragment identifiers, the issue is simply resolved: the fragment identifier only means anything at all in the context of the retrieved SVG representation. I find this entire discussion of multiple fragment identifiers inconclusive and misleading, especially without some further fleshing out of what it means for representational formats to have inconsistent semantics. www.xml.com /lpt/a/2004/01/21/deviant.html   (2045 words)

xmlhack: Fragment identifier controversies The ietf-xml-mime mailing list is discussing the use of MIME content-type identifiers and their use with fragments of documents rather than complete documents. At the apparent conclusion of an earlier discussion, Murata Makoto started by describing likely agreement from prior discussions - that fragments don't have media types - and then charged forward with some cases that may not correspond to that agreement. Gavin Thomas Nicol suggested that media types of fragments might inherit a type from their parent document, but Bert Bos showed how this inheritance can't be figured out by applications using the W3C's style sheet processing instruction. www.xmlhack.com /read.php?item=92   (172 words)

Encyclopedia article on Uniform Resource Identifier [EncycloZine]   (Site not responding. Last check: 2007-11-07) URLs are 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"). An optional fragment identifier, preceded by "#", may be appended to the end of a URI reference. An XML namespace is identified by a string, the namespace name, which must adhere to the generic URI syntax. encyclozine.com /Uniform_Resource_Identifier   (1139 words)

Including 'fragment identifier semantics' in MIME media type registration?   (Site not responding. Last check: 2007-11-07) The URI specification notes that the interpretation of a fragment identifier (the part of a URI reference after a '#') depends on the media type. However, the template for media type registration doesn't have a place to document the meaning of fragment identifiers within the media type. Originally, fragment identifiers were only used within HTML documents, so the point was somewhat moot. www.alvestrand.no /pipermail/ietf-types/2002-September/000047.html   (144 words)

wikien.info: Main_Page   (Site not responding. Last check: 2007-11-07) The syntax is designed to be generic, extensible, and able to express addresses in any character set using a limited subset of ASCII characters (for instance, whitespace is never used in a URL). URLs are classified by the "scheme" which typically identifies the network protocol used to retrieve the resource over a computer network. The term URI reference means a particular instance of a URI as it is being used in, for instance an HTML document. www.alanaditescili.net /index.php?title=Uniform_Resource_Locator   (993 words)

Topic Maps -- Overview and Basic Concepts A subject can be an individual, like Isaac Newton, the apple that fell on his head, or a document (such as this one); it may be a class of individuals, like scientists, fruits, or ISO standards; it may also be a more abstract concept like gravity or inevitability. A subject indicator can be any kind of information resource that can be interpreted by a human and that provides sufficient indication of the identity of a subject to be able to distinguish it from other subjects for the purpose of some application. Locators can thus be used in one of two ways to identify a subject: directly, as a subject locator, and indirectly, as a subject identifier. www.y12.doe.gov /sgml/sc34/document/0446.htm   (3691 words)

Fragment identifier bottoms target I also globally add names and fragment identifiers to the Previous and Next links.

Mozilla and 'fragment identifier's? - MozillaZine Forums   (Site not responding. Last check: 2007-11-07) A fragment identifier is an URL component that is usually used as a "bookmark" with in a page. That is to say, after retrieving the page, the browser will automatically jump to the position in the page identified by the fragment indentifier. He goes on to point out that some clients are sending the hash character encoded, as if it was supposed to be interpreted as data and not as the fragment indentifier character. forums.mozillazine.org /viewtopic.php?t=66652   (537 words)
