Internet Engineering Task Force (IETF) M. Jethanandani Request for Comments: 7818 Cisco Systems, Inc Category: Informational March 2016 ISSN: 2070-1721
URN Namespace for MEF Documents
Abstract
This document describes the Namespace Identifier (NID) "mef" for Uniform Resource Names (URNs) used to identify resources published by MEF Forum (https://www.mef.net). MEF specifies and manages resources that utilize this URN identification model. Management activities for these and other resources types are handled by the manager of the MEF Assigned Names and Numbers (MANN) registry.

1. Introduction
The MEF Forum (MEF) is a nonprofit international industry standards organization dedicated to the worldwide adoption of Carrier Ethernet (CE) networks and services. The forum creates specifications in the areas of Services, Architecture, and Operations and Management.
As part of these specifications efforts, there is a need to identify identifiers in a managed namespace that are unique and persistent. To ensure that this namespace's uniqueness is absolute, a registration of a specific URN Syntax [RFC2141] Namespace Identifier (NID) for use by MEF is being specified in this document.

2. URN Specification for MEF
Namespace ID:
mef
Registration information:
registration version number: 1
registration date: 2016-02-08
Declared registrant of the namespace:
Registering organization
Name: MEF Forum
Address: 6033 W. Century Boulevard, Suite 1107
Los Angeles, CA 90045
United States
Designated contact:
Role: Manager, MEF Namespace
Email: namespace@mef.net
Declaration of syntactic structure:
The syntax of namespace-specific strings for the "mef" namespace
is <NSS> in RFC 2141.
Relevant ancillary documentation:
MEF publishes information regarding the registered resources in
the MEF Assigned Names and Numbers (MANN) registry
(https://www.mef.net/MANN).

Identifier uniqueness considerations:
MEF will manage resource classes using the "mef" NID and will be
the authority for managing resources and associated subsequent
strings. MEF is expected to guarantee the uniqueness of the
strings themselves, or it may permit secondary responsibility for
certain defined resources.
MEF could allow for 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 different
resources and specific strings.
Identifier persistence considerations:
MEF will update the MEF Assigned Names and Numbers (MANN) registry
to document the registered resources that will use the "mef" NID.
Process of identifier assignment:
Assignment of a URN from the MEF namespace will be documented as
part of the MEF Assigned Names and Numbers (MANN) registry.
Process of identifier resolution:
The namespace is not listed with a Resolution Discovery System
(RDS). Therefore, this process is not relevant.
Rules for Lexical Equivalence:
The entire URN is case-insensitive.
Conformance with URN Syntax:
No special considerations
Validation mechanism:
None specified. URN assignment will be handled by procedures
implemented in support of MEF activities.
Scope:
Global

3. Examples
The following are examples of URNs that MEF is looking to assign:
urn:mef:yang:mef-services
urn:mef:yang:mef-interfaces
4. Security Considerations
There are no security considerations other than those normally
associated with the use and resolution of URNs in general, which are
described in "Function Requirements for Uniform Resource Names"
[RFC1737] and "URN Syntax" [RFC2141].
5. IANA Considerations
Per this document, IANA has added a new entry ("mef") in the "Uniform
Resource Names (URN) Namespaces" registry available from the IANA
site (https://www.iana.org).
