7. IANA Considerations

7.1. URI Scheme​

This section updates the registration of the "urn" URI scheme in the Permanent URI Registry [URI-Registry].

URI Scheme Name: urn

Status: permanent

URI Scheme Syntax: See Section 2 of RFC 8141.

URI Scheme Semantics: The "urn" scheme identifies Uniform Resource Names, which are persistent, location-independent resource identifiers.

Encoding Considerations: See Section 2 of RFC 8141.

Applications/Protocols That Use This URI Scheme Name: Uniform Resource Names are used in a wide variety of applications, including bibliographic reference systems and as names for Extensible Markup Language (XML) namespaces.

Interoperability Considerations: See Section 4 of RFC 8141.

Security Considerations: See Sections 6.4.4 and 8 of RFC 8141.

Contact: URNBIS working group [mailto:[email protected]]

Author/Change Controller: This scheme is registered under the IETF tree. As such, the IETF maintains change control.

References: None.

7.2. Registration of URN Namespaces​

This document outlines the processes for registering URN namespaces and has implications for the IANA in terms of registries to be maintained (see especially Section 6). In all cases, the IANA ought to assign the appropriate NID (formal or informal) once the procedures outlined in Section 6 have been completed.

7.3. Discussion List for New and Updated NID Registrations​

As discussed elsewhere in this document, the discussion list specified in RFC 3406 ([email protected]) is discontinued and replaced by the discussion list [email protected].
