OSM URN Namespace

Introduction

OSM is maintaining a namespace registry as a sub tree of the ETSI root urn:etsi namespace. A description of the top level ETSI URN namespace can be found on the ETSI webpage [1].

The OSM URN namespace has the following structure:

urn:etsi:osm:<OSM sub-tree>

The following sections describe the basic structure of the sub-tree and how a entry in the registry can be requested.

OSM sub-tree

NFV sub-tree	Full Namespace	Type	Description
yang	urn:etsi:osm:yang	string	Namespace for YANG modules specified in OSM. [2]

Type definitions

string = (ALPHA)0*(ALPHANUMERIC/-/_)
# a string starts with an upper- or lower-case letter followed by zero or more upper- or lower-case letters, integer numbers, hyphens or underscores

ALPHA = {a-zA-Z}
ALPHANUMERIC = {a-zA-Z0-9}

Requesting a entry

The procedure to request an entry is described as follows.

• Step #1: Send an e-mail to OSM_TSC mailing list indicating the name of the sub-tree, the contact person and the purpose of that subtree.
• Step #2: The TSC will review the proposal.
  • If the application is accepted, a new entry in the "OSM URN Namespace" will be enabled.
  • If the application cannot be accepted, it will be communicated to the contact person together with any additional information to be considered for resolving the "non-acceptance".
