UN Global Trust Register (urn:gtr)
The UN Transparency Protocol proposes a urn:gtr namespace, the UN Global Trust Register, so identifier schemes without their own IANA registration can still be expressed as resolvable URNs. Its IANA registration is pending.
Where it stands
As of 2026-10-13, the Agentic Standards Map records:
Namespace “IANA registration pending” per the UN Transparency Protocol (UNTP) specification. Not found in the Internet Assigned Numbers Authority (IANA) Uniform Resource Name (URN) namespaces registry (updated 2026-10-12, read 2026-10-13): a record named gtr.
Why it matters to agents
The specification says “Either register your own scheme with IANA or use the UN global trust register gtr URN namespace (IANA registration pending)”, pattern urn:gtr:{identifier-scheme}:{identifier-value}.
