Property identity is the schema's most-referenced concept and its biggest defect. A physical building, a parcel of land, a flat in a block — call it the property — is referred to from address, UPRN, INSPIRE ID, title-linked address, and several embedded propertyPack sub-objects. None of those four identity surfaces is canonical, and the schema offers no relation between them. This page names that gap explicitly.
Mentioned but not owned here. This page references but does not own address (London/Manchester examples populate this), titleNumber (canonical home page 38).
