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
| NFV sub-tree | Full Namespace | Type | Description |

| yang:etsi-nfv-vnfd |
urn:etsi:nfv:yang:etsi-nfv-vnfd |
string | Namespace for the YANG module that is used to model a single VNFD, according to the YANG specification available in etsi-nfv-vnfd.yang file. |
| yang:etsi-nfv-nsd |
urn:etsi:nfv:yang:etsi-nfv-nsd |
string | Namespace for the YANG module that is used to model a single NSD, according to the YANG specification available in etsi-nfv-nsd.yang file |

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 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".
