Version pinned
- The W3C AI Agent Memory Interoperability Community Group (
ai-agent-memory-interop), launched 3 June 2026, charter 1.0 adopted 19 June 2026. It has published no report or draft. A Community Group is not on the W3C standards track. - draft-saihm-memory-protocol-01, "The Sovereign AI Horizontal Memory (SAIHM) Protocol", 27 May 2026, an individual Internet-Draft intended as Informational, with no IETF standing. The group's charter treats it as a normative reference.
What is taken
Nothing normative. When receipt (A9) and erasure (A10) shapes are next revised, they are compared with these to avoid needless divergence.
Why
Open Personal Context tracks this work as prior art for receipts and erasure.
What is extended
Open Personal Context receipts record each disclosure to a recipient, not each memory write. Purge acknowledgements are recorded assertions, never proof of erasure (A10).
What is replaced or not used
The draft's post-quantum identity binding, public-chain audit anchoring and encrypted memory cells are not used.
Deviations
The group's post of 29 July 2026 and the IETF datatracker disagree on the draft's status (concluded independent-submission consideration, as against "In ISE Review"). This record cites the datatracker.
Conformance checks
None. LOG-01 and PURGE-01 cover the Open Personal Context receipt and purge shapes.
