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
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.

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.

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).

RFC 7818 Namespace for MEF March 2016
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
None specified. URN assignment will be handled by procedures implemented in support of MEF activities.
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].
