NFV URN Namespace

Introduction

ETSI ISG NFV 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 NFV URN namespace has the following structure:

urn:etsi:nfv:<NFV sub-tree>

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

NFV sub-tree

Requesting an entry (for ETSI technical groups only)

A new NFV sub-tree can only be requested by an ETSI technical group (i.e., Technical Bodies, Industry Specification Groups, Open Source Groups and Special Communities), and their working groups (if applicable).

To request a sub-tree please follow the guidelines below.

• Pre-condition: a work item running in the ETSI technical group has identified the need to enable a URN namespace. A contact person to formalize the request has been identified (e.g., a technical group official such as a WG Chair, the work item rapporteur).
• Step #1: Download the "URN namespace application template" in contribution NFVTSC(19)000003
• Step #2: Fill in the template and submit it as a contribution under the "NFV TSC" workspace of the ETSI Portal.
• Step #3: The ETSI NFV TSC will review the application.
  • If the application is accepted, a new entry in the "NFV 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".
