Qué (quién) es Uniform Resource Name - definición
UNIFORM RESOURCE IDENTIFIER (URI) THAT USES THE URN SCHEME
Namespace Specific String; URN; Uniform resource name; URN (identifier)
Uniform Resource Name
<World-Wide Web> (URN, previously Uniform/Universal Resource
Number) 1. Any URI which is not a URL.
2. A particular scheme which is currently (1991-4) under
development by the IETF, which should provide for the
resolution using Internet protocols of names which have a
greater persistence than that currently associated with
Internet host names or organisations (as used in URLs).
Uniform Resource Names will be URI schemes that improve on
URLs in reliability over time, including authenticity,
replication, and high availability.
When defined, a URN in sense 1 will be an example of a URN in
sense 2.

Uniform Resource Name
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the scheme. URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.

<World-Wide Web> (URI, originally "UDI" in some WWW
documents) The generic set of all names and addresses which
are short strings which refer to objects (typically on the
Internet). The most common kinds of URI are URLs and
relative URLs.
URIs are defined in RFC 1630.

Uniform Resource Name
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme. URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable. URNs cannot be used to directly locate an item and need not be resolvable, as they are simply templates that another parser may use to find an item.
