Relationship to URL and URN

Set diagram Venn diagrams or set diagrams are diagrams that show all hypothetically possible logical relations between a finite collection of sets . Venn diagrams were conceived around 1880 by John Venn. They are used in many fields, including set theory, probability, logic, statistics, and computer science of URI scheme categories. Schemes in the URL (locator) and URN (name) categories form subsets of URI, and also (generally) disjoint sets In mathematics and computer science, two sets are said to be disjoint if they have no element in common. For example, {1, 2, 3} and {4, 5, 6} are disjoint sets. Technically URL and URN function as resource IDs; however, one cannot exactly categorize many schemes as one or the other: we can treat all URIs as names, and some schemes embody aspects of both categories – or neither.

Computer scientists may classify a URI as a locator (URL), or a name (URN), or both.

A Uniform Resource Name A Uniform Resource Name is a Uniform Resource Identifier (URI) that uses the urn scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be a name and a locator at the same time (URN) functions like a person's name, while a Uniform Resource Locator In computing, a Uniform Resource Locator is a type of Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI. In popular language, a URL is also referred (URL) resembles that person's street address. The URN defines an item's identity, while the URL provides a method for finding it.

The ISBN The International Standard Book Number, or ISBN , is a unique, numeric commercial book identifier based upon the 9-digit Standard Book Numbering code created by Gordon Foster, now Emeritus Professor of Statistics at Trinity College, Dublin, for the booksellers and stationers W.H. Smith and others in 1966 system for uniquely identifying books provides a typical example of the use of typical URNs. ISBN 0486275574 (urn:isbn:0-486-27557-4) cites unambiguously a specific edition of Shakespeare's play Romeo and Juliet. In order to gain access to this object and read the book, one would need its location: a URL address. A typical URL for this book on a unix-like A Unix-like operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification operating system might look like the file path A path, the general form of a filename or of a directory name, specifies a unique location in a file system. A path points to a file system location by following the directory tree hierarchy expressed in a string of characters in which path components, separated by a delimiting character, represent each directory. The delimiting character is most file:///home/username/RomeoAndJuliet.pdf, identifying the electronic book saved in a local hard disk. So URNs and URLs have complementary purposes.

Technical view

One can define a URL as a URI that, in addition to identifying a resource The concept of resource is primitive in the Web architecture, and is used in the definition of its fundamental elements. The term was first introduced to refer to targets of Uniform Resource Locators , but its definition has been further extended to include the referent of any Uniform Resource Identifier (RFC 3986), or Internationalized Resource, provides a means of acting upon or obtaining a representation of the resource by describing its primary access mechanism or network "location". For example, the URL http://www.wikipedia.org/ identifies a resource (Wikipedia's Wikipedia is a free, web-based multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Its name is a portmanteau of the words wiki and encyclopedia. Wikipedia's 13 million articles (2.9 million in the English Wikipedia) have been written collaboratively by volunteers around the world, and almost all of its articles can home page The homepage is the URL or local file that automatically loads when a web browser starts or when the browser's "home" button is pressed. One can turn this feature off and on, as well as specify a URL for the page to be loaded) and implies that a user can get a representation of that resource (such as the home page's current HTML HTML, an initialism for Hypertext Mark-up Language, is the predominant markup language for web pages. It provides a means to describe the structure of text-based information in a document—by denoting certain text as links, headings, paragraphs, lists, etc.—and to supplement that text with interactive forms, embedded images, and other objects code, as encoded characters A character encoding system consists of a code that pairs a sequence of characters from a given character set with something else, such as a sequence of natural numbers, octets or electrical pulses, in order to facilitate the transmission of data (generally numbers and/or text) through telecommunication networks and/or storage of text in computers) via HTTP Hypertext Transfer Protocol is an application-level protocol for distributed, collaborative, hypermedia information systems. Its use for retrieving inter-linked resources led to the establishment of the World Wide Web from a network host named www.wikipedia.org. A Uniform Resource Name A Uniform Resource Name is a Uniform Resource Identifier (URI) that uses the urn scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be a name and a locator at the same time (URN) is a URI that identifies a resource by name in a particular namespace A namespace is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols . An identifier defined in a namespace is associated with that namespace. The same identifier can be independently defined in multiple namespaces. That is, the meaning associated with an identifier defined in one namespace may or. A URN can be used to talk about a resource without implying its location or how to access it. For example, the URN urn:isbn:0-395-36341-1 is a URI that specifies the identifier system, i.e. International Standard Book Number (ISBN The International Standard Book Number, or ISBN , is a unique, numeric commercial book identifier based upon the 9-digit Standard Book Numbering code created by Gordon Foster, now Emeritus Professor of Statistics at Trinity College, Dublin, for the booksellers and stationers W.H.

It is an open standards organization, with no formal membership or membership requirements. All participants and leaders are and by the W3C The World Wide Web Consortium is the main international standards organization for the World Wide Web (abbreviated WWW or W3). It is arranged as a consortium where member organizations maintain full-time staff for the purpose of working together in the development of standards for the World Wide Web. As of June 2009, the W3C had 388 members, have long deprecated the term URL[citation needed], as the need to distinguish between URLs and URIs rarely arises. However, in non-technical contexts and in software for the World Wide Web, the term URL remains widely used. Additionally, the term web address, which has no formal definition, often occurs in non-technical publications as a synonym for URL or URI, although it generally refers only to "http" and "https" URL schemes.

RFC 3305

Much of this discussion comes from RFC3305, titled "Report from the Joint W3C/IETF URI Planning Interest Group: Uniform Resource Identifiers (URIs), URLs, and Uniform Resource Names (URNs): Clarifications and Recommendations". This RFC outlines the work of a joint W3C/IETF working group set up specifically to normalize the divergent views held within the IETF and W3C over the relationship between the various "UR*" terms and standards. While not published as a full standard by either organization, it has become the basis for the above common understanding and has informed many standards since then.

Syntax

The URI syntax essentially offers a URI scheme In the field of computer networking, a URI scheme is the top level of the Uniform Resource Identifier naming structure. All URIs and absolute URI references are formed with a scheme name, followed by a colon character (":"), and the remainder of the URI called (in the outdated RFCs 1738 and 2396, but not the current STD 66/RFC 3986) the name like "HTTP Hypertext Transfer Protocol is an application-level protocol for distributed, collaborative, hypermedia information systems. Its use for retrieving inter-linked resources led to the establishment of the World Wide Web", "FTP File Transfer Protocol is a standard network protocol used to exchange and manipulate files over an Internet Protocol computer network, such as the Internet.

As a rule, however, a colon informs the reader that what follows proves and explains, or simply enumerates elements of what is referred to before character, and then a scheme-specific part. The specifications that govern the schemes determine the syntax and semantics Semantics is the study of meaning. The word "semantics" itself denotes a range of ideas, from the popular to the highly technical. It is often used in ordinary language to denote a problem of understanding that comes down to word selection or connotation. This problem of understanding has been the subject of many formal inquiries, over a of the scheme-specific part, although the URI syntax does force all schemes to adhere to a certain generic syntax that, among other things, reserves certain characters for special purposes, without always identifying those purposes. The URI syntax also enforces restrictions on the scheme-specific part, in order to, for example, provide for a degree of consistency when the part has a hierarchical structure. Percent-encoding is an often-misunderstood aspect of URI syntax.

History

Naming, addressing, and identifying resources

URIs and URLs have a shared history. In 1990, Tim Berners-Lee’s Sir Timothy John Berners-Lee, OM, KBE, FRS, FREng, FRSA , is an English computer scientist and MIT professor credited with inventing the World Wide Web, making the first proposal for it in March 1989. On 25 December 1990, with the help of Robert Cailliau and a young student staff at CERN, he implemented the first successful communication between proposals for HyperText Hypertext is text, displayed on a computer, with references to other text that the reader can immediately access, usually by a mouse click or keypress sequence. Apart from running text, hypertext may contain tables, images and other presentational devices. Other means of interaction may also be present, such as a bubble with text appearing when[1] implicitly introduced the idea of a URL as a short string representing a resource as the target of a hyperlink In computing, a hyperlink is a reference in a document to an external piece of information. The most common usage is in the Internet to browse through web pages: some text in the current document is highlighted so that when clicked, the browser automatically displays another page or changes the current page to show the referenced content. The. At the time it was called a "hypertext name" or "document name".[2]

Over the next three-and-a-half years, as the World Wide Web's core technologies of HTML HTML, an initialism for Hypertext Mark-up Language, is the predominant markup language for web pages. It provides a means to describe the structure of text-based information in a document—by denoting certain text as links, headings, paragraphs, lists, etc.—and to supplement that text with interactive forms, embedded images, and other objects (the HyperText Markup Language A markup language is a set of annotations to text that describe how something is to be structured, laid out, or formatted. Electronic document markup languages are embedded markup codes used to construct structured documents, used in computer typesetting, word processors, web-document editors and web browsers. With the advent of WYSIWIG markup is), HTTP Hypertext Transfer Protocol is an application-level protocol for distributed, collaborative, hypermedia information systems. Its use for retrieving inter-linked resources led to the establishment of the World Wide Web, and web browsers A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users to easily navigate their browsers to developed, a need to distinguish a string that provided an address for a resource from a string that merely named a resource emerged. Although not yet formally defined, the term Uniform Resource Locator came to represent the former, and the more contentious Uniform Resource Name came to represent the latter.

During the debate over how to best define URLs and URNs, it became evident that the two concepts embodied by the terms merely displayed aspects of the fundamental, overarching notion of resource identification. So, in June 1994 1994 was a common year starting on Saturday (link will display full 1994 Gregorian calendar), the IETF The Internet Engineering Task Force develops and promotes Internet standards, cooperating closely with the W3C and ISO/IEC standard bodies and dealing in particular with standards of the TCP/IP and Internet protocol suite. It is an open standards organization, with no formal membership or membership requirements. All participants and leaders are published Berners-Lee's RFC 1630: the first RFC In computer network engineering, a Request for Comments is a memorandum published by the Internet Engineering Task Force (IETF) describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems that (in its non-normative text) acknowledged the existence of URLs and URNs, and, more importantly, defined a formal syntax for Universal Resource Identifiers — URL-like strings whose precise syntaxes and semantics depended on their schemes. In addition, this RFC attempted to summarize the syntaxes of URL schemes in use at the time. It also acknowledged, but did not standardize, the existence of relative URLs and fragment identifiers In computer hypertext, a fragment identifier is a short string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier , and the fragment identifier points to the subordinate resource. Typically, the fragment identifier is appended to the Uniform.

Refinement of specifications

In December 1994, RFC 1738 formally defined relative and absolute URLs, refined the general URL syntax, defined how to resolve relative URLs to absolute form, and better enumerated the URL schemes then in use. The agreed definition and syntax of URNs had to wait until the publication of RFC 2141 in May 1997 1997 was a common year starting on Wednesday (link will display full 1997 Gregorian calendar).

The publication of RFC 2396 in August 1998 1998 was a common year starting on Thursday (link will display full 1998 Gregorian calendar) saw the URI syntax become a separate specification: http://www.faqs.org/rfcs/rfc2396.html, and the revision and expansion of most of the parts of RFCs 1630 and 1738 relating to URIs and URLs in general. The new RFC changed the significance of the "U" in "URI": it came to represent "Uniform" rather than "Universal". The sections of RFC 1738 that summarized existing URL schemes migrated into a separate document[3]. IANA Iana is a commune in Vaslui County, Romania keeps a registry of those schemes[4], the procedure to register them was first described in RFC 2717.

In December 1999, RFC 2732 provided a minor update to RFC 2396, allowing URIs to accommodate IPv6 addresses. Some time later, a number of shortcomings discovered in the two specifications led to the development of a number of draft revisions under the title rfc2396bis. This community effort, coordinated by RFC 2396 co-author Roy Fielding, culminated in the publication of RFC 3986 in January 2005. This RFC, as of 2009[update] the current version of the URI syntax recommended for use on the Internet, renders RFC 2396 obsolete. It does not, however, render the details of existing URL schemes obsolete; RFC 1738 still governs those, except where otherwise superseded — RFC 2616 for example, refines the "http" scheme. Simultaneously, the IETF published the content of RFC 3986 as the full standard STD 66, reflecting the establishment of the URI generic syntax as an official Internet protocol.

In August 2002, RFC 3305 pointed out that the term URL has, despite its widespread use in the vernacular of the Internet-aware public at large, faded into near-obsolescence. It now serves only as a reminder that some URIs act as addresses because they have schemes that imply some kind of network accessibility, regardless of whether systems actually use them for that purpose. As URI-based standards such as Resource Description Framework make evident, resource identification need not suggest the retrieval of resource representations over the Internet, nor need imply network-bound resources at all.

On November 1, 2006, the W3C Technical Architecture Group published "On Linking Alternative Representations To Enable Discovery And Publishing", a guide to best practices and canonical URIs for publishing multiple versions of a given resource. For example, content might differ by language or by size to adjust for capacity or settings of the device used to access that content.

The Semantic Web uses the HTTP URI scheme to identify both documents and concepts in the real world: this has caused confusion as to how to distinguish the two. The Technical Architecture Group (TAG) published an e-mail in June 2005 on how to solve this problem. The e-mail became known as the httpRange-14 resolution[5]. To explain this (rather brief) email, W3C published in March 2008 the Interest Group Note Cool URIs for the Semantic Web[6]. This explains the use of content negotiation and the 303-redirect code in more detail.

URI reference

A URI reference — another type of string — represents a URI, and, in turn, the resource identified by that URI. Informal usage does not often maintain the distinction between a URI and a URI reference, but protocol documents should not allow for ambiguity.

A URI reference may take the form of a full URI, or just the scheme-specific portion of one, or even some trailing component thereof—even the empty string. An optional fragment-identifier, preceded by "#", may appear at the end of a URI reference. The part of the reference before the "#" indirectly identifies a resource, and the fragment identifier identifies some portion of that resource.

In order to derive a URI from a URI reference, software converts the URI reference to "absolute" form by merging it with an absolute "base" URI according to a fixed algorithm. The system treats the URI reference as relative to the base URI, although if the reference itself is absolute, then the base is irrelevant. The base URI typically identifies the document containing the URI reference, although this can be overridden by declarations made within the document or as part of an external data transmission protocol. If a fragment identifier is present in the base URI, it is ignored during the merging process. If a fragment identifier is present in the URI reference, it is preserved during the merging process.

Web document markup languages frequently use URI references in places where they need to point to other resources, such as to external documents or to specific portions of the same logical document.

Uses of URI references in markup languages

Examples of absolute URIs

Examples of URI references

URI resolution

To "resolve" a URI means either to convert a relative URI reference to absolute form, or to dereference a URI or URI reference by attempting to obtain a representation of the resource that it identifies. The "resolver" component in document-processing software generally provides both services.

One can regard a URI reference as a same-document reference: a reference to the document containing the URI reference itself. Document-processing software is encouraged[by whom?] to use its current representation of the document to satisfy the resolution of a same-document reference; a new representation should not be fetched. This is only a recommendation, and document processing software is free to use other mechanisms to determine whether obtaining a new representation is warranted.

The current URI specification as of 2009[update], RFC 3986, defines a URI reference as a same-document reference if, when resolved to absolute form, it equates exactly to the base URI in effect for the reference. Typically, the base URI is the URI of the document containing the reference. XSLT 1.0, for example, has a document() function that, in effect, implements this functionality. RFC 3986 also formally defines URI equivalence, which can serve to determine that a URI reference, while not identical to the base URI, still represents the same resource and thus can be considered to be a same-document reference.

RFC 2396 prescribed a different method for determining same-document references; RFC 3986 made RFC 2396 obsolete, but RFC 2396 still serves as the basis of many specifications and implementations. This specification defines a URI reference as a same-document reference if it is an empty string or consists of only the "#" character followed by an optional fragment.

Relation to XML namespaces

XML has a concept of a namespace, an abstract domain to which a collection of element and attribute names can be assigned. An XML namespace is identified by a character string, the namespace name, which must adhere to the generic URI syntax. However, the namespace name is not considered to be a URI because the "URI-ness" of strings is, according to the URI specification, based on their intended use, not just their lexical components. A namespace name also does not necessarily imply any of the semantics of URI schemes; a namespace name beginning with "http:", for example, likely has nothing to do with the HTTP protocol. XML professionals have debated this intensively on the xml-dev electronic mailing list; some feel that a namespace name could be a URI, since the collection of names comprising a particular namespace could be considered to be a resource that is being identified, and since the Namespaces in XML specification says that the namespace name is a URI reference. But the consensus seems to suggest that a namespace name is just a string that happens to look like a URI, nothing more.

Initially, the namespace name could match the syntax of any non-empty URI reference, but an erratum to the "Namespaces In XML Recommendation" later deprecated the use of relative URI references. A separate specification, issued for namespaces for XML 1.1, allows IRI references, not just URI references, to serve as the basis for namespace names.

In order to mitigate the confusion that began to arise among newcomers to XML from the use of URIs (particularly HTTP URLs) for namespaces, a descriptive language called RDDL (Resource Directory Description Language) developed, though the specification of RDDL (http://www.rddl.org/) has no official standing and no relevant organization (such as W3C) has considered or approved it. An RDDL document can provide machine- and human-readable information about a particular namespace and about the XML documents that use it. XML document authors were encouraged[by whom?] to put RDDL documents in locations such that if a namespace name in their document somehow becomes de-referenced, then an RDDL document would be obtained, thus satisfying the desire among many developers for a namespace name to point to a network-accessible resource.
