A Uniform Resource Name (URN) Namespace for the 3rd Generation Partnership Project (3GPP)
Status of This Memo
This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited.
This document describes the Namespace Identifier (NID) for Uniform Resource Namespace (URN) resources published by the 3rd Generation Partnership Project (3GPP). 3GPP defines and manages resources that utilize this URN name model. Management activities for these and other resource types are provided by the 3GPP Support Team.
3GPP is a cooperation of international telecommunication standards bodies developing technologies for cellular networks. This activity is supported by a membership composed of network operators, equipment vendors, content providers, and other suppliers to the mobile market.
Some of the technologies being developed by 3GPP need URN 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 3GPP was deemed appropriate. Therefore, a full and complete registration will follow the namespace specification process as defined in RFC 3406 [RFC3406].
2. URN Specification for the 3GPP Namespace Identifier (NID)
registration version number: 1 registration date: 2007-11-16
Declared registrant of the namespace:
Registering organization Name: 3rd Generation Partnership Project Address: ETSI Mobile Competence Centre 650, route des Luciole 06921 Sophia-Antipolis Cedex France
3GPP will manage resources using the "3gpp" NID and will be the authority for managing the "3gpp-urn" strings. In the associated procedures, 3GPP will ensure the uniqueness of the strings themselves or shall permit secondary responsibility for management of well-defined sub-trees.
3GPP 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. Unregistered type values will only be allowed in sub-namespaces clearly marked as experimental, to help implementors avoid "leaking" experimental values into real use.
Identifier persistence considerations:
3GPP will provide clear documentation of the registered uses of the "3gpp" NID. This will be structured such that each "3gpp- urn", if needed, will have a separate description and registration table.
The registration tables and information will be published and maintained by 3GPP on its web site.
Process of identifier assignment:
3GPP 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 3GPP specifications or services
2. Registration of values or sub-trees to other entities
The 3rd Generation Partnership Project is developing a variety of enablers and applications. Some of these require information to be fully specified.
For proper operation, descriptions of the needed information must exist for the URNs and be available in a unique, reliable, and persistent manner.
As 3GPP 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 3GPP, could possibly be related to multiple different other namespaces, so further conflicts of association could occur. Thus, the intent is to utilize the 3GPP specifications manager as the naming authority for 3GPP-defined URNs and its descriptions.
The objects and descriptions required for enablers produced by 3GPP are generally available for use by other organizations. The 3rd Generation Partnership Project Support Office will provide access and support for name requests by these organizations. This support can be enabled in a timely and responsive fashion as new objects and descriptions are produced.
