Governance — deployment view

The Governance module is the smallest business module by triple count (54 across three TTLs). It carries the DPV mapping records that link OPDA kinds to GDPR personal-data categories — the load-bearing surface for the consent / data-category / data-subject-rights affordances that the UI consumer profile exposes.

Source TTL(s)

File	Role	Physical-Ontology tier
`opda-governance.ttl`	TBox: DPV mapping records (`DataCategoryMapping`, `LegalBasisMapping`, etc.)	governance/classes.md
`opda-governance-shapes.ttl`	Mapping-record identity + IC-breach shapes	governance/shapes.md
`opda-governance-annotations.ttl`	DPV self-referential annotations (this module is the DPV mapping; its annotation graph documents the mapping discipline itself)	governance/annotations.md

Named graph(s)

Named graph IRI	Source TTL	Triples	`owl:versionIRI`
`https://opda.org.uk/pdtf/graph/governance`	`opda-governance.ttl`	42	`https://opda.org.uk/pdtf/harness/release/governance/1.0.0/`

`https://opda.org.uk/pdtf/graph/governance-annotations`	`opda-governance-annotations.ttl`	6	—

Load order: TBox graph imports foundation + vocabularies. Governance mapping records reference DPV terms via dct:references per ADR-0012 (reference-not-import).

Derived-profile membership

Profile	`opda-governance.ttl`	`opda-governance-shapes.ttl`	`opda-governance-annotations.ttl`
opda-validation	included (classes + properties + subClassOf + labels)	included (all triples)	excluded
opda-ui	included (all triples; UI consumers drive DPV-aware consent forms from these mappings)	included (all triples)	included (all triples)
opda-inference	included (classical-logic axioms only; DPV `dct:references` triples stripped)	excluded	excluded

The Governance module is structurally peculiar: it is itself the mapping-records layer that the other modules’ -annotations.ttl files cite. Its own annotation graph carries mostly meta-commentary on the DPV mapping discipline rather than per-class baselines.

Overlay bindings

No overlay targets Governance classes directly. Mapping records are referenced by overlays through the modules’ annotation graphs (when the UI profile renders a BASPI5 Person field, the DPV mapping record in opda-governance.ttl is what drives the special-category-data disclosure), but no overlay binds Governance shapes via sh:targetClass.

A future ICO-compliance overlay or DPIA-mandated overlay is the expected first overlay to target Governance.
