	URN: Universal Resource Name		URN: Universal Resource Name

			From the [http://tools.ietf.org/html/rfc3986 RFC Specification],

			<blockquote>
			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.g., its network "location"). 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.
			</blockquote>
