Description of Working Group:


    * * *  Problem Statement  * * *

    Uniform Resource Names (URNs) are location-independent, persistent
    identifiers for information resources.

    The RFCs defining URNs were published in 1997-2001.  They rely on old
    (or even provisional) basic documents on the concepts of URI and URL. At
    that time there was almost no URN implementation experience.

    Since then, the URN system has gained significant popularity, and
    roughly 40 formal URN Namespaces have been defined and registered with
    IANA.  Hundreds of millions of resources have been assigned URNs; this
    enables searching of and persistent linking to these documents,
    artifacts, and other objects.  However, the URN system lacks a
    foundation that is consistent in terminology and formal description with
    present (Full) Internet Standards.

    The core URN RFCs -- RFC 2141 (URN Syntax), RFC 3406 (Namespace
    Definition Mechanisms) -- are based on outdated framework documents and
    understanding of digital archiving. All references in RFC 2141 point to
    "work in progress" or documents that have been superseded at least once.

    The lack of a standard definition of the 'urn' URI scheme fosters
    recurring discussions on what URNs are and IETF commitment to them.
    There is a need to clarify that URNs are specific URIs (namely those
    using the 'urn' URI scheme) and hence all general URI rules apply to URNs.

    There also is a need to update some namespace registrations for at least
    two reasons: the standards specifying the relevant underlying namespaces
    (such as International Standard Book Number (ISBN)) have been
    amended/expanded since the original specification of the related URN
    namespace and the WG's update of the basic URN-related RFCs might
    introduce or identify inconsistencies.

    * * *  Objectives for the Working Group  * * *

    This working group is chartered to update the key RFCs describing the
    URN system, including RFC 2141 (URN Syntax), RFC 3406 (Namespace
    Definition Mechanisms), and review and update selected URN namespace
    specifications including those for ISBN, National Bibliography Numbers
    (NBN) and International Serial Standard Number (ISSN).

    For all document revisions, backward compatibility with previous
    URN-related RFCs will be retained.

    The WG will produce an updated set of URN-related RFCs. All documents
    will be on the Standards-Track or BCP. These updates will provide a
    normative foundation for URNs and assure uniformity of the URN
    assignment and resolution concepts and procedures at the abstract level.

    Details and tasks (the WG will approach these tasks in roughly this order):

      a)  Core URN specifications

      For RFC 2141, this revision will include in particular:
      - an update of the formal syntax specification in the light of the
        URI Standard (STD 66, RFC 3986) using the ABNF from STD 68
        (RFC 5234);
      - a formal IANA registration for the 'urn' URI scheme using the
        current template from BCP 35 (RFC 4395);
      - a revised set of URN examples and
      - an update of the sections describing how URNs are resolved
        in the Internet, based on the current practices.

      RFC 3406 (BCP 33) will be aligned with the current IANA procedures
      and terminology as defined in BCP 26 (RFC 5226).

      b) URN Namespace specifications

      The WG will focus on updating the RFCs related to the key
      bibliographic identifier systems:
      - RFC 3187 (URN Namespace for International Standard Book Numbers),
      - RFC 3188 (URN Namespace for National Bibliography Numbers), and
      - RFC 3044 (URN Namespace for International Serial Standard Number).

      All these identifier systems have been updated since these RFCs were
      written in a way that makes revision of the namespace registration
      necessary.

      c) Further work

      The WG will support the current registrants of URN namespaces.  It
      will review the legacy URN namespace definition documents and if
      needed, provide advice to their registrants on how to bring these
      registrations in line with the upcoming URN-related RFCs.
      However any work on updating such specifications beyond giving an
      advice would require rechartering of the WG.
