Internet Engineering Task Force (IETF) B. Leiba
Request for Comments: 6924 Huawei Technologies
Updates: 2648 April 2013
Registration of Second-Level URN Namespaces under "ietf"
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".

"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.
