Scheme name: uuaid

Status: Provisional

Applications/protocols that use this scheme name:

The Universal Agent Protocol (UAP) v1 (IAASO-0001, ratified by the
IAASO standards council) uses uuaid URIs as the canonical identifier
for autonomous agents and related registry objects, for agent
identity resolution and credential verification.

The UUAID registry resolves and verifies uuaid identifiers over
HTTPS at https://api.uuaid.org (machine API) and
https://registry.uuaid.org (human-readable registry).

The @uuaid/* npm packages (@uuaid/core, @uuaid/sdk, @uuaid/cli,
@uuaid/vault, @uuaid/mcp) parse, validate, mint, and resolve uuaid
identifiers.

IAASO standards (International Autonomous Agents Standards
Organization, https://iaaso.org) reference the scheme, including
IAASO-0001 "Universal Agent Protocol (UAP) v1" and the draft
IAASO-1001 "Autonomous Agent Identifier Standard".

Additional Info:
Scheme syntax summary: a uuaid URI has no authority component; the scheme-specific part is an opaque hierarchical sequence of colon-separated ASCII segments in two profiles, discriminated by segment count: compact (3 segments: <namespace>:<object-type>:<uuidv7>, e.g. uuaid:foundation:agent:019f2e47-1c32-7c4b-937e-a25e2c502844) and federated (4 segments: <subject-class>:<jurisdiction>:<namespace>:<local-id>). Full ABNF and semantics: https://github.com/uuaid/spec (UAP v1, ratified as IAASO-0001). The name 'uuaid' does not conflict with any entry in the URI Schemes registry as of 2026-07-06. A companion W3C DID method (did:uuaid) registration is in review (w3c/did-extensions PR #730); the two forms carry the same identifier. Happy to route this through uri-review&ietf.org for community review if the designated expert prefers.
