https://datatracker.ietf.org/doc/draft-ietf-spice-glue-id/ is on Thursday's IESG Telechat. It was pointed out by Amanda Baber of IANA that the draft had failed to request registration of the URN urn:glue, which it uses. The thread in which Amanda pointed out this omission is:
[IANA #1444305] Ballot issued: <draft-ietf-spice-glue-id-05.txt> to Proposed Standard
I have separately requested that the secretariat post the attached draft, which this registration. The registration request in the editor's draft can be viewed at https://ietf-wg-spice.github.io/draft-ietf-spice-glue-id/draft-ietf-spice-glue-id.html#name-urn-namespace-registration. The completed registration template for your review is:
7.2.1. urn:glue
Namespace Identifier: glue
Version: 1
Date: 2026-03-02
Registrant: IETF
Purpose: GLobal Unique Enterprise (GLUE) identifier namespace,
established by [[ this specification ]]
Syntax: As specified in the glue-uri ABNF entry in Section 3 of [[
this specification ]]
Assignment: Specification Required (Section 4.6 of [RFC8126]) basis
Security and Privacy: GLUE URNs are public identifiers for public
entities.
Interoperability: GLUE URNs encapsulate other existing identifier
namespaces. Therefore, they provide a globally unique equivalent
to identifiers within those local namespaces. Some of those
namespaces may also utilize URNs.
Resolution: Resolution of GLUE URNs, which are identifiers, is not
performed.
Documentation: [[ this specification ]]
Additional Information: N/A
Revision Information: N/A
Thank you,
-- Mike

This specification establishes a URN namespace for
GLobal Unique Enterprise (GLUE) Identifiers.
This enables URN identifiers to be used for businesses and organizations.
It enables organizational identities from existing authorities to be represented within this URN namespace.

The reason to allow the Designated Experts to
