Uniform Resource Name (URN) Namespaces for Broadband Forum
draft-bbf-bbf-urn-02

Abstract

This document describes the Namespace Identifiers (NIDs) 'bbf', 'broadband-forum-org', and 'dslforum-org' for Uniform Resource Names (URNs) used to identify resources published by Broadband Forum (BBF). BBF specifies and manages resources that utilize these three URN identification models. Management activities for these and other resource types are handled by BBF.

Table of Contents

1. Introduction

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) [RFC2141] Namespace IDs (NID) for use by BBF are being specified in this document, in full conformance with the NID registration process specified in [RFC3406].

The 'bbf' NID is for new work efforts related to data models for protocols other than its CPE WAN Management Protocol (CWMP) [TR-069]. The 'broadband-forum-org' and 'dslforum-org' NIDs are used for all data models related to CWMP [TR-069].

5. Example

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.

6. Namespace Considerations

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.

7. Community Considerations

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-RESOURCES]. BBF will also maintain the corresponding specifications where the registered resources are referenced or used.

8. IANA Considerations

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.

9. Security Considerations

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