However (see the footnote [http://www.w3.org/DesignIssues/Model.html here]), this was changed to Universal Resource Identifier in discussions within the URI working Group of the [[Internet Engineering Task Force]] (IETF), and is now called the [[Uniform Resource Identifier]] |
Meanwhile, the term [[Uniform Resource Locator]] (URL) was introduced to denote a string that provided an address for a resource, while the term Uniform Resource Name (URN) came to represent a string that merely names a resource. URL and URN are types of URIs (see [http://en.wikipedia.org/wiki/Uniform_Resource_Identifier URI]. | Meanwhile, the term [[Uniform Resource Locator]] (URL) was introduced to denote a string that provided an address for a resource, while the term Uniform Resource Name (URN) came to represent a string that merely names a resource.
