Uniform Resource Name (URN) Namespaces for Broadband Forum

Broadband Forum (BBF) is a non-profit industry alliance driving broadband wireline solutions and empowering converged packet networks worldwide to better meet the needs of vendors, service providers and their customers. BBF develops multi-service broadband packet networking specifications addressing interoperability, architecture and management. Its work enables home, business and converged broadband services; encompassing customer, access and backbone networks. Occasionally, BBF specification efforts require identifiers in a managed namespace so that they are unique and persistent. To ensure that the uniqueness is absolute, the registration of three specific Uniform Resource Name (URN) Namespace IDs (NID) for use by BBF are being specified in this document, in full conformance with the NID registration process specified in . The 'bbf' NID is for new work efforts related to data models for protocols other than its CPE WAN Management Protocol (CWMP) . The 'broadband-forum-org' and 'dslforum-org' NIDs are used for all data models related to CWMP .

Namespace ID: bbf Registration Information: registration version number: 1 registration date: YYYY-MM-DD [RFC Editor: Please replace YYYY-MM-DD with the date of approval of this document for publication as an RFC.] Declared registrant of the namespace: Registering organization Name: Broadband Forum Address: 48377 Fremont Boulevard, #117, Fremont, CA 94538, USA Designated contact Role: Manager, Namespace Email: help@broadband-forum.org Declaration of syntactic structure: The syntax of namespace specific strings for the 'bbf' namespace is <NSS> in . Relevant ancillary documentation: BBF publishes information regarding the registered resources on the BBF Assigned Resources web page . Identifier uniqueness considerations: BBF will manage resource classes using the "bbf" NID and will be the authority for managing resources and associated subsequent strings. BBF is expected to guarantee the uniqueness of the strings themselves or it may permit secondary responsibility for certain defined resources. BBF could allow the use of experimental type values for testing purposes only. Note that using experimental types may create collisions as multiple users may use the same values for resources and specific strings. Identifier persistence considerations: BBF will update the BBF Assigned Resources web page to document the registered resources that use the "bbf" NID. Process of identifier assignment: BBF will provide procedures for registration of each type of resource that it maintains. Process for identifier resolution: The namespace is not listed with a resolution discovery system; this is not applicable for this URN registration. Rules for Lexical Equivalence: No special considerations; the rules for lexical equivalence of apply. Conformance with URN Syntax: No special considerations. Validation mechanism: None specified. URN assignment will be handled by procedures implemented in support of BBF activities. Scope: Global

The following examples represent hypothetical URNs that could be assigned by BBF. urn:broadband-forum-org:cwmp:datamodel-1-5 urn:bbf:yang:fast The first of these defines an URN to be used for CPE WAN Management Protocol (CWMP) data models conforming to rules for BBF's CWMP suite of specifications.

BBF develops various specifications that require the use of data models. URN Namespaces are key constructs to manage the definitions of those data models reliably with persistence and uniqueness. The use of URNs should also help specification authors to maintain different versions of URNs and dependencies between URNs, across different versions of BBF specifications, if they so wish.

Participants involved in the development and usage of Broadband Forum specifications will benefit from the publication of this namespace by providing consistent and reliable names for the XML namespaces, schema locations, and similar identifiers of physical data models published within BBF specifications. The BBF specifications are publicly available and are licensed to manufacturers on a reasonable and nondiscriminatory basis. BBF will maintain the allocation of resources for the "bbf", "broadband-forum-org", and "dslforum-org" NIDs at the following publicly-viewable location: . BBF will also maintain the corresponding specifications where the registered resources are referenced or used.

This document adds threee new entries in the urn-namespaces registry. The namespaces should be "bbf", "broadband-forum-org", and "dslforum-org". This is the defining document. The entries can be found at: http://www.iana.org/assignments/urn-namespaces and any associated mirrors.

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