In 1990, Tim Berners-Lee's proposals for hypertext implicitly introduced the idea of a URL as a short string representing a resource that is the target of a hyperlink. URIs are used to identify anything described using the Resource Description Framework (RDF), for example, concepts that are part of an ontology defined using the Web Ontology Language (OWL), and people who are described using the Friend of a Friend vocabulary would each have an individual URI. The web technologies that use URIs are not limited to web browsers. Other URIs provide only a unique name, without a means of locating or retrieving the resource or information about it, these are Uniform Resource Names (URNs).

A URI identifies the resource by name at the specified location or URL. A URL provides the location of the resource. Some URIs provide a means of locating and retrieving information resources on a network (either on the Internet or on another private network, such as a computer filesystem or an Intranet) these are Uniform Resource Locators (URLs). URIs may be used to identify anything, including real-world objects, such as people and places, concepts, or information resources such as web pages and books. Uniform Resource Identifier (URI) AbbreviationĪ Uniform Resource Identifier ( URI) is a unique sequence of characters that identifies a logical or physical resource used by web technologies.
