	Uniform Resource Identifier - Wikipedia, the free encyclopedia
		A Uniform Resource Identifier (URI), is an Internet protocol element consisting of a short string of characters that conform to a certain syntax.
		A Uniform Resource Locator (URL) is a URI that, in addition to identifying a resource, provides means of acting upon or obtaining a representation of the resource by describing its primary access mechanism or network "location".
		A Uniform Resource Name (URN) is a URI that identifies a resource by name in a particular namespace.

	Uniform Resource Locator - Wikipedia, the free encyclopedia
		A Uniform Resource Locator (URL) is a string of characters conforming to a standardized format, which refers to a resource on the Internet (such as a document or an image) by its location.
		Every URL is a type of Uniform Resource Identifier (URI), or, more precisely, the set of URLs is a proper subset of the set of URIs.
		A URL is classified by its scheme, which typically indicates the network protocol used to retrieve a representation of the identified resource over a computer network.

	RFC 3986 (rfc3986) - Uniform Resource Identifier (URI): Generic Syntax (Site not responding. Last check: 2007-10-21)
		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.
		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.
		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.

	RFC 2396 (rfc2396) - Uniform Resource Identifiers (URI): Generic Syntax (Site not responding. Last check: 2007-10-21)
		Having identified a resource, a system may perform a variety of operations on the resource, as might be characterized by such words as `access', `update', `replace', or `find attributes'.
		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.
		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.

	Uniform Resource Identifier (URI): Generic Syntax
		A Uniform Resource Identifier (URI) is a compact sequence of characters for identifying an abstract or physical resource.
		A URI is an identifier, consisting of a sequence of characters matching the syntax rule named in Section 3, that enables uniform identification of resources via a separately defined, extensible set of naming schemes (Section 3.1).
		A host identified by a registered name is a sequence of characters that is 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.

		Introduction The Uniform Resource Identifier (URI) protocol element and generic syntax is defined by RFC 3986 [6].
		Those who wish to describe resource identifiers that are useful as IRIs should define the corresponding URI syntax, and note that the IRI usage follows the rules and transformations defined in RFC 3987.
		Definition of operations As part of the definition of how a URI identifies a resource, a URI scheme definition SHOULD define the applicable set of operations that may be performed on a resource using the URI as its identifier.

		The IRI document defines a new protocol element named the Internationalized Resource Identifier (IRI) "as a complement to the Uniform Resource Identifier (URI)." URIs are composed of sequence of characters chosen from a limited subset of the repertoire of US-ASCII characters.

	About "info" URIs - Frequently Asked Questions (Site not responding. Last check: 2007-10-21)
		For a demonstration in the difficulty of mapping legacy identifiers the reader is referred to RFC 3151 which provides a set of complex transcriptions for mapping SGML formal public identifiers onto the URN URI syntax.
		A secondary motivator is to equivalence resource identifiers in Web descriptions of information structures to allow those structures to be normalized or merged with other like structures, e.g.
		It was recognized that these resource identifiers would have a much wider applicability to many Web-based applications and it was decided to decouple this URI scheme from the OpenURL Framework and to name it info.

		The ability to identify resources in both the virtual and physical world is key to any markup language, including HTML.
		URIs, or "Uniform Resource Identifiers" are simply a common technique for defining links, perhaps the most commonly used of which is the ubiquitous URL (Uniform Resource Locator).
		It is important to keep in mind, however, that URIs are not restricted to network resources only, but may also be written to include things not "directly retrievable on the web" (Manola and Miller, 2003), such as a books, insects, cars, a spec of dirt, etc.

	URI (Uniform Resource Identifier) (Linktionary term)
		A URL (Uniform Resource Locator) is a specific address used with some protocol such as HTTP or FTP that follows the general URI format.
		Tim Berners-Lee outlined the concept of URI in RFC 1630 (Universal Resource Identifiers in WWW: A Unifying Syntax for the Expression of Names and Addresses of Objects on the Network as Used in the World-Wide Web, June 1994).
		According to Berners-Lee, the URI concept is based on the fact that network resources can be mapped into a concept of "objects" that have some kind of name, address, or identifier.

		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.
		This is not a part of the URI as such, but is intended for the "user agent" (browser) to interpret after the resource has been retrieved.

	The Semantic Web In Breadth
		Because we use a uniform system of identifiers, and because each item identified is considered a "resource," we call these identifiers "Uniform Resource Identifiers" or URIs for short.
		Yes, a URL is a type of URI that does provide a way to get information about a resource, or perhaps to retrieve the resource itself, and other methods for providing information about URIs and the resources they identify are under development.
		A namespace is just a way of identifying a part of the Web (space) from which we derive the meaning of these names.
