    Property

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

    A physical immovable property whose identity is fixed by spatial-material continuity (with a legal-record-discontinuity override) and persists through re-numbering, repair, and re-registration, as distinct from the legal estate vested in it and the registered title that records it.

    Physical property. UFO Substance Kind; DOLCE Endurant / PhysicalObject. IC: spatial-material continuity with Kendall+Davis legal-record-discontinuity-override hybrid (ODR-0005 §3a). Hard cases: demolition; subdivision; merger; replacement; first-registration; flat with split UPRN.

    Classification

    Classified under UFO meta-category Substance Kind — a design-time classification (UFO-informed, not UFO-grounded), not an entailed type

    DOLCE: Endurant / PhysicalObject (Masolo et al. 2003 D18 §4.1). UFO: Substance Kind (Guizzardi 2005 Ch. 4 §4.2 — Sortal, Rigid, supplies own IC).

ONE shared location-description property reused across those points. Plain string datatype per ODR-0008 §Q5a; flat per §Q6a.

RANGE CORRECTED 2026-07-05 (RML gap-closing session): council session-028 Q3 (ODR-0024 R3) had swept this into the monetary walk as opda:MonetaryAmount alongside ~17 genuinely numeric sibling leaves (annualGroundRent, rent, securityDeposit, etc. — all schema `type: number`), without re-checking this ONE field's own schema type individually; it is `type: string` in the v3 schema (confirmed by direct inspection), a genuinely different shape from its monetary-walk siblings, not a best-effort magnitude extractable from free text. Flat per §Q6a.
