                        URN Namespace for ETSI Documents

    Abstract

       This document describes the Namespace Identifier (NID) "etsi" for
       Uniform Resource Names (URNs) used to identify resources published by
       the European Telecommunications Standards Institute
       (http://etsi.org).  ETSI specifies and manages resources that utilize
       this URN identification model.  Management activities for these and
       other resource types are handled by the manager of the ETSI Protocol
       Naming and Numbering Service (PNNS).

    RFC 8515                   Namespace for ETSI              February 2019

    1.  Introduction

       ETSI is a nonprofit international industry standards organization
       that produces globally acceptable standards for information and
       communication technologies including fixed, mobile, radio, broadcast,
       internet, aeronautical, and other areas.

       As part of these efforts, there is a need to specify identifiers in a
       managed namespace that are unique and persistent.  To ensure that
       this namespace's uniqueness is absolute, the registration of a
       specific Uniform Resource Name (URN) [RFC8141] Namespace Identifier
       (NID) for use by ETSI is specified in this document, in full
       conformance with the NID registration process specified in [RFC8141].

    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
          Email: 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 ETSI
          defines and that 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.  Servers
          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) [RFC8141].

          The entire URN is case-insensitive.

    RFC 8515                   Namespace for ETSI              February 2019

       Assignment:

          ETSI will maintain the list of registered subtrees that use the
          "etsi" NID in the "ETSI URN Namespace" registry at
          <https://portal.etsi.org/PNNS/GenericAllocation/
          ETSIURNNamespace.aspx>.  The registry describes the <NSS>, how
          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 by
          validating them against the existing content of the registry.
          ETSI may also permit secondary responsibility for certain defined
          resources.  Once a subtree assignment is made, it cannot be
          deleted or reassigned.

          ETSI may allow 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" [RFC6963].

       Security and Privacy:

          See Section 4 of RFC 8515.

       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 [RFC7950], 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 apart from what are
       normally associated with the use and resolution of URNs in general,
       which are described in "Functional Requirements for Uniform Resource
       Names" [RFC1737] and "Uniform Resource Names (URNs)" [RFC8141].

    5.  IANA Considerations

       IANA has registered "etsi" in the "Formal URN Namespaces" registry
       using the template in Section 2.
