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. The term "Uniform Resource Name" URN has been used historically to refer to both URIs under the "urn" scheme [RFC] , 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.
A Uniform Resource Identifier URI is a unique sequence of characters that identifies a logical or physical resource used by web technologies. 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. 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.
