                   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.

RFC 7818                    Namespace for MEF                 March 2016


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: [email protected]

  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).
