Uniform Resource Name (URN) Namespaces for Broadband Forum
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.

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 that address 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
Stark, et al. Informational [Page 2]RFC 8057 URN Namespaces for Broadband Forum January 2017
Uniform Resource Name (URN) [RFC2141] Namespace Identifiers (NIDs)
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 the Customer Premises Equipment (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]. BBF has used the latter two NIDs for many years without
formally registering them and has published widely implemented
specifications that use these NIDs. Use of the "dslforum-org" NID
started prior the organization's 2008 name change from DSL Forum to
Broadband Forum.

2. bbf Registration
Namespace ID:
bbf
Registration Information:
registration version number: 1
registration date: 2016-12-05
Declared registrant of the namespace:
Registering organization
Name: Broadband Forum
Address: 5177 Brandin Court, Fremont, CA 94538, USA
Designated contact
Role: Manager, Namespace
Email: help@broadband-forum.org
Stark, et al. Informational [Page 3]RFC 8057 URN Namespaces for Broadband Forum January 2017
Declaration of syntactic structure:
The syntax of namespace-specific strings for the "bbf" namespace
is <NSS> in [RFC2141].
Relevant ancillary documentation:
BBF publishes information regarding the registered resources on
the BBF Assigned Resources web page [BBF-RESOURCES].
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 may, at the namespace resource manager's discretion,
designate/allocate 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
[BBF-RESOURCES] to document the registered resources that use the
"bbf" NID.
Process of identifier assignment:
BBF procedures for URN assignment are provided at [BBF-RESOURCES].
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
[RFC2141] apply.
Conformance with URN Syntax:
No special considerations.
Stark, et al. Informational [Page 4]RFC 8057 URN Namespaces for Broadband Forum January 2017
Validation mechanism:
None specified. URN assignment will be handled by procedures
implemented in support of BBF activities.

5. Examples
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.
Stark, et al. Informational [Page 8]RFC 8057 URN Namespaces for Broadband Forum January 2017
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.
Three NIDs are defined. The "broadband-forum-org" and "dslforum-org"
NIDs have been used for many years by BBF without formal
registration. (Broadband Forum changed its name from DSL Forum in
2008.) As they are referenced by multiple BBF specifications
currently in common use, BBF is formalizing them. The new "bbf" NID
will be used for new work efforts that are not enhancements, updates,
or extensions to work that currently makes use of the "broadband-
forum-org" and "dslforum-org" NIDs.
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 three new entries in the formal urn-namespaces
registry. The namespaces are "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.
