URN Namespace for ETSI Documents
draft-mahesh-etsi-urn-05

Abstract

This document describes the Namespace Identifier (NID) 'etsi' for Uniform Resource Names (URNs) used to identify resources published by European Telecommunications Standards Institute (http://etsi.org). ETSI 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 ETSI Protocol Naming and Numbering Service (PNNS).

1. Introduction

ETSI is a nonprofit international industry standards organization, that produces globally acceptable standards for Information & Communication Technologies including fixed, mobile, radio, broadcast, internet, aeronautical and other areas.

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 Uniform Resource Names (URNs) Namespace Identifier (NID) for use by ETSI is being specified in this document, in full conformance with the NID registration process specified in the document.

1.1. Terminology

2. URN Specification for ETSI

Namespace Identifier:

• etsi

Version:

• 1

Date:

• 2018-10-22

Registrant:

• ETSI Protocol Naming and Numbering Service (PNNS)
• European Telecommunications Standards Institute (ETSI)
• 650, Route des Lucioles, Sophia Antipolis 06560, France
• pnns@etsi.org

Purpose:

The Namespace Identifier (NID) 'etsi' for Uniform Resource Names (URNs) will be used to identify resources published by ETSI. These might include published standards or protocols that it defines and which make use of URNs. These namespaces are globally unique. The URN namespace will be used in public networks by clients to configure and manage resources in the network. It is the servers that will enforce the uniqueness of the namespaces by using the namespace and the XPath associated with the managed node in the network, when accessing a resource.

Syntax:

• The syntax of namespace specific strings for the 'etsi' namespace is <NSS> in Uniform Resource Names (URNs).

The entire URN is case-insensitive.

Assignment:

• ETSI will maintain the list of registered subtrees that use the "etsi" NID at https://portal.etsi.org/PNNS/GenericAllocation/ETSIURNNamespace.aspx, in the ETSI URN Namespace (EUN) registry. It will describe the <NSS>, how the namespaces will be allocated, and how experimental namespaces can be used within the allocated URN.
• ETSI will manage resource classes using the "etsi" NID and will be the authority for managing resources and associated subsequent strings. ETSI will guarantee the uniqueness of the strings themselves, by validating it against the existing content of the registry. It may also permit secondary responsibility for certain defined resources. Once a subtree assignment is made, it cannot be deleted or reassigned.
• ETSI may allow for use of experimental type values in specific subtrees, for testing purposes only. Note that using experimental types may create collision as multiple users may use the same values for different resources and specific strings. All experimentation must follow the guidance set forth in A Uniform Resource Name (URN) Namespace for Examples.

Interoperability:

There are no known interoperability issues at this time.

Resolution:

• It is not foreseen that URNs within this namespace will undergo resolution.

Documentation:

• Documentation can be found at https://portal.etsi.org/PNNS/GenericAllocation/ETSIURNNamespace.aspx.

3. Examples

The following are examples of URNs that ETSI is looking to assign:

• urn:etsi:yang:etsi-nfv
• urn:etsi:yang:etsi-nfv-vnf
• urn:etsi:yang:etsi-nfv-pnf

Although all of these examples are related to network management with YANG, URNs related to other kinds of resources might be assigned in the future, in which case a "sub-identifier" other than "yang" might be created.

4. Security Considerations

There are no additional security considerations that are normally associated with the use and resolution of URNs in general, which are described in Function Requirements for URN, Uniform Resource Names (URNs).

5. IANA Considerations

IANA is requested to register the formal URN namespace "etsi" using the template given above in Section 2.
