    Properties

    The OPDA ontology declares 75 object properties (the relational backbone — what links to what) and 205 datatype properties (the literal-valued attributes), sourced from the SPARQL-extracted ontology model. Each property links to its own page at /pdtf/{localName} — with its full domain/range, inverse, the SHACL shapes that constrain it, and dct:source provenance.

    The leaseTerm object property is the case-independent exception: its representation is at /pdtf/object-properties/lease-term.

    domain / range are informative, not enforced

    Under the inference / validation boundary (ODR-0029), rdfs:domain and rdfs:range are documentation — a multi-domain property reads as a union and is never used to entail types. The actual enforcement is value-keyed SHACL (SHACL shapes). The domain/range shown below is the declared documentary intent.

    Object properties · 75

    The relational predicates. Note that several "monetary" predicates in the descriptive module (rent, listPrice, currency …) are declared object properties because their range is a value-structure or coded scheme rather than a literal.

    Comparison renderings

    The native per-property pages above are the authoritative reference (ADR-0044). The bake-off OWL tools remain as comparison extras for the exhaustive axiom view:

    See Classes for the subjects these properties attach to, Vocabularies (SKOS) for the coded value-spaces many ranges point at, Datatypes for the literal value-spaces, and SHACL shapes for the constraints that actually enforce them. The namespace each term is minted under is on Namespaces & prefixes. Full index: Index & glossary.
