Vocabulary Catalogue Amendments

SUPERSEDED 2026-05-26 by ODR-0002 via Scope-Check 1 (Q4 vote 7-1-1 retire; Hendler dissent on permanence preserved). This record is retained as a historical artefact and anchor for the Council Session 001 provenance below. The amendments it records are folded into ODR-0002’s ## Change log subsection inside ## Rules — that is now the authoritative current state of the catalogue. Readers seeking current tiering MUST go to ODR-0002; the tables below are frozen at session-001’s deliberation snapshot. Session 002 ratifies the fold.

Context

ODR-0002 established OPDA’s vocabulary catalogue — a closed three-tier set (Core / Conditional / Defer) with canonical URI, role, and adoption pattern per entry — surveyed from the H&M programme before any PDTF-specific modelling had been attempted. Council Session 001 (Q2) then scoped the PDTF-to-ontology work against that catalogue and, in doing so, made decisions that change ODR-0002’s tiering or rationale for specific entries. Two pivots in particular: OWL-Time, which ODR-0002 placed at Conditional and which the PDTF brief had initially excluded, was brought into active scope on coherence grounds (PROV-O instants without OWL-Time intervals is incoherent for proprietorship, lease, and claim-validity); and the mapping/policy cluster (SSSOM, ODRL) was held back where the data-model-only round presents no target. The session also opened OBO RO (no consensus) and FOAF (subsequently ruled out programme-wide).

The original question this ODR answered — how should the partial supersession be recorded to preserve provenance? — was itself superseded by Scope-Check 1 (2026-05-26), which ruled the amendment-ODR pattern is not the right convention (FIBO catalogues, DCMI terms, W3C WD discipline all collapse). The amendments now live in ODR-0002’s ## Change log.

Decision

Superseded. The original decision (record amendments as a partial-supersession amendment) is replaced by ODR-0002’s ## Change log-inside-## Rules pattern. The amendments are unchanged; only their authoritative home changes.

Rules

Supersession scope

This record is wholly superseded by ODR-0002 — the amendments it carried (OWL-Time Conditional adoption; DCAT Conditional; SSSOM deferral; ODRL deferred-policy; DPV Phase-1; Dublin Core rationale; BBO/ArchiMate out) now live as ## Change log rows in ODR-0002’s ## Rules, attributed to Session 001 Q2. The two open questions originally routed here (OBO RO → ODR-0005; FOAF / W3C Org → ODR-0006) remain routed — but their pointers live in ODR-0002, not here. Hendler’s recorded dissent on the retirement (Scope-Check 1 Q4: “every governance act stays permanently”) is preserved in the plan’s risks table (docs/plan/council-followup-sessions.md §9) as a live methodological position, not silenced.

Amended entries (superseded in part)

These ODR-0002 catalogue entries are changed by this record:

Vocabulary	ODR-0002 said	Session 001 decision	Rationale
OWL-Time	Conditional, “use only where bitemporal/interval semantics genuinely needed” — PDTF brief excluded it	ADOPT (Conditional), in scope for this programme — reverses the exclusion	PROV-O’s `prov:atTime` (instant) without OWL-Time intervals for proprietorship, leases, claim-validity is incoherent (Guizzardi/Gandon). ≈6-3 over “await a concrete consumer” dissent (Allemang/Davis).
DCAT 3	Conditional	Confirmed Conditional (Davis wanted Core; Baker held Conditional)	Ontology-as-published-dataset + reference data; near-zero marginal cost over `dct:`. Not Core — no catalogue task this round.
SSSOM / SEMAPV	Conditional (“pair with `semapv:`”)	Deferred for internal overlay refs; use `dct:source` to form-question IRIs now	SSSOM earns its place mapping to external vocabularies; for single-source internal refs it is machinery without a target (Gandon/Knublauch). Cagle dissent recorded (≈5-4).
ODRL	Conditional, “restrict to access-control layers”	Vocabulary adopted; policy-authoring deferred to Phase 2	ODRL `Policy`/`Permission` bite only on instances, which this round forbids — an ODRL TBox alone asserts nothing (Guarino). See ODR-0012.
DPV family	Conditional	Phase-1 annotation adopted; broader TBox class vocab is a live question	See ODR-0012 — Pandit’s recorded dissent on lawful-basis/consent/purpose class vocabulary.
Dublin Core	Core (“administrative metadata”)	Reclassified rationale: “commons substrate” — no tier change	DCAT/PROV-O/SKOS/VANN all already depend transitively on `dct:` (Baker); adopting it formalises the implicit. Strengthened justification, same tier.
BBO, ArchiMate	Conditional/Defer	Out for this programme	No process- or capability-modelling task. Unanimous.

OWL-Time moves into active scope carrying ODR-0002’s adoption pattern (canonical URI + local SHACL + no owl:imports); consumed by Transactions & Lifecycle (ODR-0007) for proprietorship/lease/claim-validity intervals.

Open questions raised (routed, not adopted)

OBO RO — Kendall proposed for transitive part-of (flat → block → estate); Davis rejected (biology-flavoured; use dct:isPartOf). No consensus — left open, routed to ODR-0005.
FOAF / W3C Org ontology — Session 001 reopened FOAF; since ruled out (programme decision). ODR-0002’s Defer-row negative on FOAF stands. The remaining Kind-layer choice routed to ODR-0006 is W3C Org ontology vs bespoke opda:, with prov:Agent for the provenance role only.

Survives unchanged

This record does not touch:

The entire Core tier (RDF, RDFS, OWL 2, XSD, SHACL, SKOS, Dublin Core, VANN) — membership and canonical URIs stand; only Dublin Core’s rationale is restated.
The adoption pattern for every Conditional entry (canonical URI + local SHACL + no owl:imports + vann: header + recorded provenance).
The Defer-tier reasoning for entries the PDTF round did not test — schema.org, DCAT-AP / DCAT-AP EU, FIBO, SOSA/SSN, QUDT, GeoSPARQL — all stand as ODR-0002 reasoned them.
The three-tier framing (Core / Conditional / Defer) and the closed-set discipline (new admissions require a new ODR).

Enforcement notes

Each amended row above is confirmed against session-001 Q2 — tallies (OWL-Time ≈6-3; SSSOM ≈5-4 with Cagle dissent) and arguments match the transcript.
ODR-0002’s affected rows carry a “Superseded in part by ODR-0014” note pointing here; the Core tier, adoption pattern, and untouched Defer reasoning are unchanged in ODR-0002.
OWL-Time adoption is confirmed downstream by ODR-0007 (interval modelling), carrying the canonical-URI + local-SHACL + no-owl:imports adoption pattern.
This is a partial supersession: ODR-0002 remains the standing catalogue for everything outside the amended scope above. Whether ODR-0002’s frontmatter status flips to superseded is left to the validator (odr-review) as a soundness item rather than asserted here.

Amendment-pattern supersession flow

This diagram traces how the amendment-ODR convention itself was evaluated and superseded — the decision captured in the ## Decision section above.

Alternatives

Edit ODR-0002 in place — erases the provenance of why each tier moved and which deliberation moved it, collapsing two distinct authorship events into one undated table.
A fresh full catalogue ODR superseding ODR-0002 wholesale — falsely implies the whole catalogue was re-deliberated when only a handful of entries were touched, and discards ODR-0002’s still-valid survey reasoning for the untouched tiers.

Consequences

Each tiering change is recorded with its Council session, argument, and tally — the catalogue’s provenance is layered, not flattened.
The temporal tier now matches what the model needs: OWL-Time intervals alongside PROV-O instants remove the Guizzardi/Gandon incoherence.
SSSOM and ODRL-policy deferral keeps unused machinery out of this round; both remain adoptable once a target (external mappings; consent instances) arrives.
The OBO RO question is recorded as open and FOAF as ruled out, each routed to its owning ODR — neither silently dropped nor prematurely tiered.
The catalogue must be read across two records (ODR-0002 baseline + this amendment) until a future consolidation; readers must hold both to see current tiering.
Modellers consuming OWL-Time apply ODR-0002’s adoption pattern (canonical URI + local SHACL + no owl:imports + vann: header) in ODR-0007.
The Kind-layer-vocabulary question (W3C Org vs bespoke opda:) is owned by ODR-0006; the part-of question by ODR-0005.
