From b3c6c1dfdbc507a909d0c7af1ff15c4ad43e2cd9 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Mon, 14 Sep 2026 22:00:58 +0100 Subject: [PATCH] docs(iana): mark vnd.a2ml as never submitted, superseded, and expand the name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Owner rulings 2026-09-14. 1. application/vnd.a2ml was NEVER filed with IANA. The header previously read "Submission Date: 2026-04-03 (Revision 2)", which reads as though the type is registered. It is not. Any reader — human or agent — arriving at this file would have concluded that vnd.a2ml is an allocated media type and that vnd.deed needed a change request against it. Both conclusions are false. The header now states plainly that the document was never submitted, that the string is unregistered, and that application/vnd.deed supersedes it, with a link to the registration actually being filed. 2. "A2ML" expands to "Attestation Markup Language". Three repositories each carried a different expansion (Attested Agent Markup Language here, Attestation Markup Language in deed-ecosystem, Annotated Markup Language in standards). The attestation reading, WITHOUT "agent", is canonical for every historical reference — it makes the superseded format a general attestation format rather than an agent-specific one, which matches what DEED became. The other two are to be corrected wherever they appear. 3. Drops the "Canonical copy: format-registrations/iana/a2ml-media-type.txt" line. That location exists nowhere: not as a directory (0 hits across standards, a2ml, deed-ecosystem and k9-ecosystem, against positive controls of 126/7/47/139 paths matching "k9"), and not as a repository (both hyperpolymath/ and metadatastician/ return 404, with a live positive control and a 404 negative control; no local checkout, against a control that found three "standards" checkouts by the same method). The same line is dropped from the vnd.deed and vnd.k9 registrations in hyperpolymath/standards, so all three layers agree.
