                     Uniform Resource Names (URNs)
                  draft-ietf-urnbis-rfc2141bis-urn-12

Abstract

   A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI)
   that is assigned under the "urn" scheme and a particular URN
   namespace, with the intent that the URN will be either a persistent,
   location-independent resource identifier or in some cases an abstract
   designator that is persistent but that does not identify a resource.
   With regard to URN syntax, this document defines the canonical syntax
   for URNs (in a way that is consistent with URI syntax), specifies
   methods for determining URN equivalence, and discusses URI
   conformance.  With regard to URN namespaces, this document specifies
   a method for defining a URN namespace and associating it with a
   namespace identifier, and describes procedures for registering
   namespace identifiers with the Internet Assigned Numbers Authority
   (IANA).  This document obsoletes both RFC 2141 and RFC 3406.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
   material or to cite them other than as "work in progress."

   This Internet-Draft will expire on December 17, 2015.
