docs(iana): apply owner rulings — provisional filing, fresh registration, A2ML expansion - #797

Conversation
There was no registration document for the DEED media type anywhere in the estate — verified 2026-09-14 across standards, a2ml, deed-ecosystem and k9-ecosystem. application/vnd.a2ml and application/vnd.k9 both have one; deed, the format that supersedes a2ml, had none. Derived from those two. Nothing in it is invented: every normative claim is taken from deed/spec/DEED-GRAMMAR-SPEC.adoc or deed/spec/abnf/deed.abnf as they stand on main. Decisions and where they come from: - Subtype `vnd.deed`, no structured syntax suffix. Not a judgement call — DEED-GRAMMAR-SPEC.adoc:7 already declares `:media-type: application/vnd.deed` normatively, and it matches the reasoning application/vnd.k9 already records for dropping `+nickel` (RFC 6838 Section 4.2.8: unregistered suffixes SHOULD NOT be used). - Encoding `8bit`, not `binary` as vnd.a2ml uses. vnd.a2ml is binary because of its @opaque payload construct. DEED has no such construct: grep for opaque/include/eval across deed.abnf returns 0 against a positive control of 28 ABNF rules. - The four head forms, the filename dispatch table and the exact-stem-first rule are transcribed from deed.abnf rather than restated from memory, including the constraint that <stem> in repo-file MUST NOT be "estate". - Interoperability considerations lead on the "=" hazard because that is the one this estate actually has: a large population of files bearing the ecosystem extension were written TOML-style by tooling with no grammar to consult. The ABNF states it flatly — "The only bracket is '('. A file using '=' is not a deed." — so the registration says parsers MUST reject rather than accept leniently. Deliberately NOT included: the @trust_override / @adjust_override mechanism. It is designed, but "override" occurs 0 times in DEED-GRAMMAR-SPEC.adoc at v0.1.0. A registration must describe the grammar that exists, not the one intended, so it is recorded as an open item instead — flagged because overrides are security-relevant to any processor and would require a revision if they land. Three items are left open for the owner at the end of the file, none blocking: whether to submit against a v0.1.0 DRAFT spec; the dangling `format-registrations/iana/` canonical path that vnd.a2ml and vnd.k9 both declare and which exists in no repository (0 hits, positive controls of 126/7/47/139 paths matching "k9"); and whether vnd.a2ml was ever actually filed, since if it was, deed needs a change request rather than a fresh registration.

…ion, A2ML expansion Five rulings of 2026-09-14, applied across every media-type registration in this repository so that no two layers disagree. 1. FILE PROVISIONALLY, THEN RE-FILE. The spec is at v0.1.0 DRAFT and RFC 6838 permits registering against a published specification either way. The ruling is to claim the subtype name NOW with a provisional registration and re-file a full one once the grammar is marked Stable — the point of filing is to lock the name down, and an unclaimed vnd.deed is the risk being managed. "Provisional registration" changes from No to Yes and states what the re-filing is expected to change (specification reference and Security considerations only; name, encoding and fragment semantics are settled). 2. "A2ML" EXPANDS TO "Attestation Markup Language". Three repositories each carried a different expansion — Attested Agent Markup Language (deed-core), Attestation Markup Language (deed-ecosystem), Annotated Markup Language (standards). The deed-ecosystem reading is canonical for every historical reference: dropping "agent" makes the superseded format a general attestation format rather than an agent-specific one, which matches what DEED actually became. The expansion is now stated where the registration explains the earlier working name. 3. application/vnd.a2ml was NEVER filed with IANA. application/vnd.deed is therefore a FRESH registration, not a change request. The "Deprecated alias names" field is corrected: vnd.a2ml is NOT a registered alias, and the unregistered string is recorded only so implementors understand its origin (MAY accept on input, MUST NOT emit). 4. The "Canonical copy: format-registrations/iana/<x>-media-type.txt" convention is DROPPED from every registration. 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 (hyperpolymath/format-registrations and metadatastician/format-registrations both 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). Both earlier registrations described themselves as synchronised copies of an original that was never created. The document beside the specification is now the canonical one, with no second copy to drift. NOTE: rhodium-standard-repositories/spec/ and docs/proofs/ still cite format-registrations as a real T3 repo at /var/mnt/eclipse/repos/. Those claims are now known to be false and are left for a separate sweep. 5. application-vnd.k9+nickel-registration.txt is renamed to application-vnd.k9-registration.txt. Its filename contradicted its own body, which registers bare application/vnd.k9 and explains why, citing RFC 6838 Section 4.2.8. Exactly one reference to the old filename existed and is updated in the same commit. One item remains open before submission, and it is deliberately not guessed: the @trust_override / @adjust_override mechanism is designed for this family but appears NOWHERE in the v0.1.0 grammar (0 occurrences of "override" against 28 ABNF rules), so it is absent from Security considerations, which describe only what the registered grammar admits. If overrides land normatively, this registration needs a revision — an override construct is security-relevant to any processor consuming a deed.

- Line 83: Update the DEED delimiter description in the documentation to state
that each form uses a matching parenthesis pair, with both “(” and “)”
delimiters, rather than claiming it has only one bracket character. Keep the
surrounding ABNF guidance unchanged.
- Around line 95-97: Align the UTF-8 BOM statement with the normative ABNF:
either define mandatory removal of a leading U+FEFF before matching the
spdx-line grammar, or remove the requirement that parsers accept and silently
consume it. Ensure the registration text and deed/spec/abnf/deed.abnf describe
the same parsing behavior.

Describe the delimiters accurately.
The ABNF defines each form with a matching ( and ) pair. Saying that DEED has “exactly one bracket character: (” is technically false and can mislead implementers about the required closing delimiter. State that DEED uses one bracket type with both delimiters.

Align the BOM requirement with the normative grammar.
deed/spec/abnf/deed.abnf is normative for parsing and begins with spdx-line, whose first literal is ;;. It defines no U+FEFF production or pre-parse removal rule. A parser that applies the ABNF directly can therefore reject input that the registration requires it to accept. Define BOM removal before ABNF matching, or remove the MUST accept requirement.

Align the UTF-8 BOM statement with the normative ABNF: either define mandatory
removal of a leading U+FEFF before matching the spdx-line grammar, or remove the
requirement that parsers accept and silently consume it. Ensure the registration
text and deed/spec/abnf/deed.abnf describe the same parsing behavior.

What this does
Applies the owner's rulings of 2026-09-14 across every media-type
registration in this repository, so that no two layers disagree.
The five rulings
1. File provisionally, then re-file. The spec is at v0.1.0 DRAFT and RFC 6838
permits registering against a published specification either way. The ruling is
to claim the subtype name now with a provisional registration and re-file a
full one once the grammar is marked Stable — the point of filing is to lock the
name down, and an unclaimed
vnd.deedis the risk being managed.Provisional registrationchangesNo→Yesand states what the re-filing isexpected to change (specification reference and Security considerations only;
the subtype name, encoding and fragment semantics are settled).
2. "A2ML" expands to "Attestation Markup Language". Three repositories each
carried a different expansion and all three were being cited as authoritative:
Dropping "agent" makes the superseded format a general attestation format
rather than an agent-specific one, which matches what DEED actually became.
⛔ The inverse also holds and is stated in the file: DEED is not an acronym.
"deed" is used in its ordinary legal-instrument sense — a signed declaration of
record — and no expansion should be supplied for it.
3.
application/vnd.a2mlwas NEVER filed with IANA.application/vnd.deedis therefore a fresh registration, not a change request. The "Deprecated
alias names" field is corrected:
vnd.a2mlis not a registered alias, and theunregistered string is recorded only so implementors understand its origin
(processors MAY accept on input, MUST NOT emit).
4. The phantom canonical-copy line is dropped from all three registrations.
format-registrations/iana/<x>-media-type.txtexists nowhere:standards,a2ml,deed-ecosystemandk9-ecosystem, against positive controls of 126/7/47/139 paths matching "k9";hyperpolymath/format-registrationsandmetadatastician/format-registrationsboth 404, with a live positive controland a 404 negative control;
standardscheckouts by the same method.
Both earlier registrations described themselves as synchronised copies of an
original that was never created. The document beside the specification is now
the canonical one, with no second copy to drift.
5.
application-vnd.k9+nickel-registration.txt→application-vnd.k9-registration.txt.The filename contradicted its own body, which registers bare
application/vnd.k9and explains why, citing RFC 6838 §4.2.8. Exactly onereference to the old filename existed and is updated in the same commit.
One item deliberately left open
The
@trust_override/@adjust_overridemechanism is designed for this familybut appears nowhere in
DEED-GRAMMAR-SPEC.adocat v0.1.0 — verified2026-09-14, 0 occurrences of "override" against 28 ABNF rules. It is therefore
deliberately absent from Security considerations, which describe only what the
registered grammar actually admits. If overrides land in the normative grammar
this registration needs a revision, because an override construct is
security-relevant to any processor consuming a deed. Not guessed here.
