Abstract

   This document describes the Namespace Identifier (NID) for Uniform
   Resource Namespace (URN) resources published by the Open Mobile
   Alliance (OMA).  OMA defines and manages resources that utilize this
   URN name model.  Management activities for these and other resource
   types are provided by the Open Mobile Naming Authority (OMNA).

. Introduction

   OMA is a specification development body developing technologies for
   mobile devices.  This activity is supported by a membership comprised
   of network operators, equipment vendors, content providers and other
   suppliers to the mobile market.

   Some of the technologies being developed by OMA need XML namespaces
   that are managed so that they are unique and persistent.  To assure
   that the uniqueness is absolute, the registration of a specific NID
   for use by OMA was deemed appropriate.  Therefore, a full and
   complete registration will follow the namespace specification process
   as defined in [RFC3406].

                        URN Namespace for OMA                July 2005


. URN Specification for "oma" NID

2.1 Namespace ID:

   The NID "oma" is requested.

2.2 Registration Information:

   registration version number: 1
   registration date:           2005-07-18

2.3 Declared registrant of the namespace:

   Registering organization
      Name:    Open Mobile Alliance
      Address: 4275 Executive Square
               Suite 240s
               La Jolla, CA 92037

   Designated contact
      Role:    Technical Program Manager
      Email:   TPM@omaorg.org

2.4 Declaration of syntactic structure:

   The Namespace Specific String (NSS) of all URNs that use the "oma"
   NID will have the following structure:

         urn:oma:{OMAresource}:{ResourceSpecificString}

   where the "OMAresource" is a US-ASCII string that conforms to the URN
   syntax requirements [RFC2141] and defines a specific class of
   resource type.  Each resource type has a specific labeling scheme
   that is covered by "ResourceSpecificString" which also conforms to
   the naming requirements of [RFC2141].

   OMA maintains a naming authority, the Open Mobile Naming Authority
   (OMNA), that will manage the assignment of "OMAresources" and the
   specific registration values assigned for each resource class.

2.5 Relevant ancillary documentation:

   The Open Mobile Naming Authority (OMNA) provides information on the
   registered resources and the registrations for each.  More
   information about OMNA and the registration activities and procedures
   to be followed are available at:

      http://www.openmobilealliance.org/tech/omna

2.6 Identifier uniqueness considerations:

   The OMNA will manage resources using the "oma" NID and will be the
   authority for managing the resources and subsequent strings
   associated.  In the associated procedures, OMNA will ensure the
   uniqueness of the strings themselves or shall permit secondary
   responsibility for management of well-defined sub-trees.

   OMA may permit use of experimental type values that will not be
   registered.  As a consequence, multiple users may end up using the
   same value for separate uses.  As experimental usage is only intended
   for testing purposes, this should not be a real issue.

2.7 Identifier persistence considerations:

   OMNA will provide clear documentation of the registered uses of the
   "oma" NID.  This will be structured such that each OMAresource will
   have a separate description and registration table.

   The registration tables and information will be published and
   maintained by OMNA on its web site.

2.8 Process of identifier assignment:

   OMNA will provide procedures for registration of each type of
   resource that it maintains.  Each such resource may have three types
   of registration activities:

     1) Registered values associated with OMA specs or services
     2) Registration of values or sub-trees to other entities
     3) Name models for use in experimental purposes

2.9 Process for identifier resolution:

   The namespace is not listed with an RDS; this is not relevant.

2.10 Rules for Lexical Equivalence:

   No special considerations, the rules for lexical equivalence of
   [RFC2141] apply.

2.11 Conformance with URN Syntax:

   No special considerations.

2.12 Validation mechanism:

   None specified.  URN assignment will be handled by procedures
   implemented in support of OMNA activities.

2.13 Scope:

   Global

. Examples

   The following examples are representative urns that could be assigned
   by OMNA.  They may not be the actual strings that would be assigned.

   urn:oma:ac:oma-presence
     Defines the urn to be used for the Application Characteristic
     object definition for providing attributes to the Presence enabler
     defined in OMA.

   urn:oma:drms:org-foobar
     Defines the urn associated with the Digital Rights Management
     System object definition allocated to foobar which is an external
     organization that made request via OMNA for a drms urn.

. Namespace Considerations

   The Open Mobile Alliance is developing a variety of application and
   service enablers.  Some of these enablers depend upon supporting
   information (e.g. data descriptions, attributes, etc.) to be fully
   specified.  For proper operation, descriptions of the needed
   supporting information must exist and be available in a unique,
   reliable and persistent manner.  These dependencies provide the basis
   of need for namespaces, in one form or another.

   As the Open Mobile Alliance work is ongoing and covers many technical
   areas, the possibility of binding to various other namespace
   repositories has been deemed impractical.  Each object or
   description, as defined in OMA, could possibly be related to multiple
   different other namespaces so further conflicts of association could
   occur.  Thus the intent is to utilize the Open Mobile Naming
   Authority, operated by OMA, as the naming authority for OMA defined
   objects and descriptions.

. Community Considerations

   The objects and descriptions required for enablers produced by OMA
   are generally available for use by other organizations.  The Open
   Mobile Naming Authority will provide access and support for name
   requests by these organizations.  This support can be enabled in
   timely and responsive fashion as new objects and descriptions are
   produced.  These will be enabled in a fashion similar to current OMNA
   support.

. Security Considerations

   There are no additional security considerations other than those
   normally associated with the use and resolution of URNs in general.

. IANA Considerations

   The objective of this registration is for the requested NID to be
   entered into the IANA registry for URN NIDs.  This would result in an
   update to http://www.iana.org/assignments/urn-namespaces and any
   associated mirrors.

   normative references.
