!!! Overview[1]
[{$pagename}] In September [2001|Year 2001], the [W3C] issued a note clarifying the terms [URI] ([Uniform Resource Identifier]), [URL] ([Uniform Resource Locator]), and [URN] ([Uniform Resource Name]). 

The key difference between these three categories of identifiers are:
* [URI] and [IRI] are the terms for any type of identifier used to identify a [resource] on the Web.
* [URL] is the term for any type of [URI] that can be resolved or de-referenced to locate a representation of a [resource] on the Web (e.g., Web page, file, image, etc.)
* [URN] is the term for a specific type of [URI] intended to persistently identify a [resource] \\(i.e., an identifier that will never change no matter how often the resource moves, changes names, changes owners, etc. URNs are intended to last forever.)
