    Class descriptive context

    Comparable

    https://opda.org.uk/pdtf/ComparableTurtle ↓

    An information artefact recording a sale or rental of a comparable property that supports a Valuation, sourced from Land Registry or VOA data and individuated by that market-data provenance feeding the valuation's derivation chain.

    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.
