    Comparable

    https://opda.org.uk/pdtf/Comparable

    No DPV class-level baseline; PII coverage flows transitively via the linked opda:Property (which carries the postal-address baseline). Per ODR-0018 §Rule 1: only direct PII-bearing Kinds declare a baseline; transitively-linked Kinds do not duplicate the upstream baseline.

    Classification

    UFO: Information Object (corrected from "Substance Kind" per ODR-0008d Rule 3). Land Registry Price Paid Data + VOA records (regulator-cited per ODR-0011 §4a).

    Constraints

    ComparableIdentityKeyShape sh:Violation

    Class-promoted descriptive Information Object MUST carry prov:wasGeneratedBy to its issuing activity per ODR-0008 §Q4a three-criterion test (authority-retrieved provenance is the IC discriminator for class-promotion).

    ComparableInternalStructureShape sh:Info

    The comparable record's authority reference / number SHOULD be recorded (IC component 2 of 3 — authority reference; ODR-0008d Rule 3), carried by opda:disclosureDetail with an instance-level dct:source to the reference question.

    ComparableInternalStructureShape sh:Info

    The comparable record's issue date SHOULD be named via prov:generatedAtTime (IC component 3 of 3 — issue date; ODR-0008d Rule 3).

    ComparableInternalStructureShape sh:Info

    The comparable record's issuing authority SHOULD be named via prov:wasAttributedTo (IC component 1 of 3 — issuing authority; ODR-0008d Rule 3).
