Object property property context

has survey

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

Relates a Property to a professional survey report retrieved for it: a distinct survey entity with its own provenance chain and issue/supersession lifecycle, reached separately from the property's own construction-type observation.

Property → opda:Survey join predicate. The survey's construction-type observation stays on the Property as opda:constructionType (its rdfs:domain); this join reaches the survey report itself as a distinct PROV-O artefact (RICS Level 2 professional survey, issued/superseded/re-issued/withdrawn lifecycle, ODR-0008d Rule 3).
