Odr Review

ODR Review

Lint changed ODR frontmatter and section structure for cross-corpus modifying-relations violations, referential-integrity issues, and DCAP-conformance.

When to use

Before committing or merging changes that touch docs/ontology/odr/*.md. Also as a periodic CI check across the full ODR corpus.

--lint-only skips DCAP profile-conformance and runs only the cross-corpus + referential-integrity lints (faster pre-commit hook).

Lints

The DCAP at docs/ontology/odr/DCAP.md is the normative profile. This skill enforces five rules.

Lint 1 — Cross-corpus modifying-relations

# Pseudocode.
own_corpus = "ODR" if record.path.startswith("docs/ontology/odr/") else "ADR"

# supersedes: must be intra-corpus
for ref in record.frontmatter.get("supersedes", []):
    if not ref.startswith(own_corpus):
        fail(f"{record.id}: supersedes: {ref} crosses corpora (intra-corpus only)")

# implements: ODR refs intra-corpus; external URIs pass-through
for ref in record.frontmatter.get("implements", []):
    if ref.startswith(("ODR-", "ADR-")) and not ref.startswith(own_corpus):
        fail(f"{record.id}: implements: {ref} crosses ODR↔ADR (intra-corpus only for intra-corpus refs)")
    # External schema URIs (e.g. pdtf-v3:propertyPack.titleNumber) are allowed; no resolution check

depends-on: is intentionally NOT in the loop — it may cross corpora freely.

Lint 2 — Referential integrity

For each ODR-NNNN reference in supersedes, depends-on, or implements:

• Resolve ODR-NNNN (and ODR-NNNNa..m sub-record forms) to a glob over docs/ontology/odr/ODR-NNNN*-*.md.
• Resolve ADR-NNNN to docs/adr/NNNN-*.md (and legacy companion patterns).
• If no file matches, fail loud with the source ODR ID, the relation slot, and the missing reference.

External schema URIs in implements: (anything not matching ^(ODR|ADR)-\d{4}[a-m]?$) pass through without resolution check.

Lint 3 — Council reference

If council: is set, the session file docs/ontology/odr/council/<council-value>-*.md MUST exist. Missing → fail.

If council: is omitted, this lint is satisfied (author-only decisions are first-class).

Lint 4 — DCAP profile conformance

Skip if --lint-only. Read docs/ontology/odr/DCAP.md. For each changed ODR:

• Frontmatter keys MUST be a subset of: status, date, kind, tags, scope, council, supersedes, depends-on, implements. Required keys (all except council) MUST be present.

• status MUST be one of: proposed, accepted, rejected, deprecated, superseded.

• kind MUST be one of: methodology, architecture, pattern, mapping, programme.

• date MUST be ISO YYYY-MM-DD.

• Typed-slot list shape: supersedes/depends-on/implements/scope/tags MUST be lists.

• H2 sections follow the canonical MADR 4.x spine plus named extensions (the DCAP §Sections table is the authority — read it in the repo under review). H2 headings MUST be a subset of the declared set below, appear in this declared order, and each at most once. Required sections MUST be present; optional ones MAY be omitted; any undeclared H2 heading fails the lint.

  #	Heading	Required
  1	## Context and Problem Statement	yes
  2	## Decision Drivers	no
  3	## Considered Options	yes
  4	## Decision Outcome	yes (MUST contain a ### Consequences H3; ### Confirmation / ### Supersession scope: optional)
  5	## Pros and Cons of the Options	no
  6	## More Information	no
  7	## Rules (named extension)	no
  8	## Vote and Dissent (named extension)	no
  9	## Amendments (named extension)	no
  10	## Mapping (named extension)	no

  Missing required section, undeclared heading, wrong order, or duplicate → fail with the offending heading. (Pre-unification ODRs used a retired six-section ## Context / ## Decision / ## Rules / ## Alternatives / ## Consequences / ## References spine — those must be migrated to the spine above, not validated against it.)

• H1 MUST be present, MUST NOT carry an ODR-NNNN: prefix. The only content permitted between the H1 and the first H2 is a single optional status/supersession admonition blockquote (e.g. > **SUPERSEDED …**).

Any heading not declared in the DCAP fails this lint until the DCAP is updated in the same commit (undeclared-extension policy).

Lint 5 — Inverse-authoring prohibition

Search the changed ODR's frontmatter for any of: superseded-by:, depended-on-by:, implemented-by:. If present, fail loud — these are derived at index time, not authored.

Lint 6 — A9 per-kind discipline (pattern + mapping ODRs)

Source: ODR-0001 §"What an ODR records" (Session A9 amendment, 2026-05-27).

For records with kind: pattern or kind: mapping, the ## Rules section MUST name three things:

1. UFO/DOLCE meta-category — a literal mention of one of: Substance Kind, Endurant, NonPhysicalEndurant, Role, RoleMixin, Phase, Relator, Quality, Quale-in-Region, Quality Region, Quality Value, Substance Kind label, Method/plan code, Mode. (The seven-category framework ratified at S011 Q8 plus the original four.)
2. Identity Criterion (IC) over named hard cases — at least two hard cases named verbatim (e.g. "demolition", "subdivision", "merger", "first-registration", "title closure", "register transfer"; or the record's equivalent).
3. Artefact realisation — explicit pointer to how the pattern manifests as engineering output (Turtle template, SHACL shape, generator rule, mapping table, etc.).

Severity: warning on status: proposed; blocker on status: accepted.

kind: methodology | architecture | programme are relaxed (per A9 §Per-kind discipline — only pattern and mapping carry the MUST).

Lint 7 — URI-shape verification (layer convention from S004 Q2)

Source: ODR-0004 §Rules.2 (layer-segregated naming).

For records with kind: pattern, extract (UFO category, class URI) pairs from ## Rules (text-based heuristic; look for opda:<Name> adjacent to a category mention). Verify the URI form matches the layer convention:

Violations are reported as warnings — the heuristic is fragile; failures may be false positives in narrative prose. Authors override by inline-commenting the URI usage.

Lint 8 — ODR-0017 SHACL-AF rule pattern verification

Source: ODR-0017 — SHACL-AF Non-Blocking Data-Quality Rules Pattern.

For records citing ODR-0017 in implements:, the ## Rules section MUST name:

1. Hard case — the specific data-quality concern the SHACL-AF rule materialises (e.g. "UPRN succession chain", "deprecation lineage", "INSPIRE-only locatedness").
2. Severity tier — sh:Info for non-blocking advisory; sh:Warning allowed only when explicitly justified; sh:Violation is forbidden at the data-graph layer for this pattern (the ODR-0017 §2a amendment narrows sh:Violation to meta-shape-over-shape-graph drift only — see ODR-0013 §Q1).
3. Non-blocking discipline — explicit confirmation that the rule materialises into the annotation graph (not the data graph) and does not block validation.

Severity: blocker on status: accepted.

Lint 9 — ODR-0018 DPV co-annotation placement

Source: ODR-0018 — DPV Class-Level Co-Annotation Pattern.

For records citing ODR-0018 in implements:, the ## Rules section MUST place DPV co-annotations (e.g. dpv-pd:hasPersonalDataCategory) in the annotation graph (opda-annotations.ttl), NOT in the class graph (opda-classes.ttl) or the shapes graph (opda-shapes.ttl). Lint inspects the prose for the placement claim. CI tests against the three-graph separation rule (ODR-0004 §3a five-part CI test) are the authoritative enforcement; this lint is a documentation guard.

Severity: warning (documentation-level; CI enforces the actual placement).

Steps

1. Identify changed records — Run git diff --name-only main...HEAD (or the specified branch) and filter for docs/ontology/odr/ODR-*.md. Skip README.md, DCAP.md, DCAP-audit-log.md, council session siblings (council/), and _template.md. If no record changes, exit 0.

2. Parse YAML frontmatter — For each changed ODR file, Read and parse YAML between the leading --- fences. If frontmatter is malformed, fail loud (exit non-zero).

3. Run Lint 1 (cross-corpus modifying-relations) — As specified above.

4. Run Lint 2 (referential integrity) — As specified above.

5. Run Lint 3 (council reference) — As specified above.

6. Run Lint 4 (DCAP profile conformance) — Skip if --lint-only. Read docs/ontology/odr/DCAP.md. Compare frontmatter keys, section headings, ordering, cardinality.

7. Run Lint 5 (inverse-authoring prohibition) — As specified above.

8. Run Lint 6 (A9 per-kind discipline) — As specified above. Skip records where kind is not pattern or mapping.

9. Run Lint 7 (URI-shape verification) — As specified above. Skip records where kind is not pattern. Heuristic failures are warnings, not blockers.

10. Run Lint 8 (ODR-0017 SHACL-AF rule pattern) — As specified above. Skip records that do not cite ODR-0017 in implements:.

11. Run Lint 9 (ODR-0018 DPV co-annotation placement) — As specified above. Skip records that do not cite ODR-0018 in implements:.

12. Report — If any lint failed, exit non-zero with a structured report:

On clean run: exit 0 with (no issues found).

Notes

• The DCAP at docs/ontology/odr/DCAP.md is the prose normative spec. New extensions or section moves require a DCAP edit in the same commit.
• The DCAP audit log at docs/ontology/odr/DCAP-audit-log.md records review entries — even when no changes were made.
• This lint is a text-based check. SHACL shape graphs and pySHACL CI are explicitly out of scope; the DCAP-conformance lint is the prose-equivalent.
• Symmetry with adr-review: this skill is the ODR-side counterpart. The cross-corpus rule is enforced from both directions.
