      Registration of Second-Level URN Namespaces under "ietf"

Abstract

 RFC 2648 defines the "ietf" URN namespace and a number of sub-
 namespaces.  RFC 3553 defines an additional sub-namespace, "params",
 and creates a registry to document allocations under that.  But there
 is no registry that lists, in one place, all sub-namespaces of
 "ietf".  This document creates and populates such a registry, thereby
 changing the mechanism defined in RFC 2648 for adding new sub-
 namespaces of "ietf".

1. Introduction

 "A URN Namespace for IETF Documents" [RFC2648] defines the "ietf" URN
 namespace and a number of sub-namespaces.  "An IETF URN Sub-namespace
 for Registered Protocol Parameters" [RFC3553] defines an additional
 sub-namespace, "params", and creates a registry to document
 allocations under that.  But there is no registry that lists, in one
 place, all sub-namespaces of "ietf".  This document creates and
 populates such a registry, thereby changing the mechanism defined in
 RFC 2648 for adding new sub-namespaces of "ietf".

2. IANA Considerations

 There is currently a top-level registry group called "IETF Protocol
 Parameter Identifiers", which contains one registry, "IETF URN Sub-
 namespace for Registered Protocol Parameters".  IANA has taken the
 following three actions:

 Action 1: Renamed the group "IETF Protocol Parameter Identifiers",
 giving it the new name "Uniform Resource Name (URN) Namespace for
 IETF Use".  The existing registry in that group remains, and its name
 is unchanged.  Its registration procedure has been updated to "IETF
 Review" (formerly called "IETF Consensus").

 Action 2: Added a new registry to the renamed group.  The new
 registry is called "IETF URN Sub-namespaces", and new registrations
 will use the IETF Review policy [RFC5226], which provides for IETF
 consensus in order to add a new URN namespace under "ietf".  The new
 registry appears first in the group, to provide a human-friendly,
 top-down resolution of the namespace hierarchy.

 Action 3: Populated the new registry as follows:

 IETF URN Sub-namespaces

 Registration Procedures: IETF Review
 Reference: [RFC6924]

 Note: This is the Official Registry for sub-namespaces of the 'IETF'
 URN Namespace.
