Valuation

Summary

Property valuation — RICS-regulated professional or automated-model output. [Substance Kind (informational); UFO Substance Kind / PROV-O Entity]. Class-promoted per S008 Q4 three-criterion test (RICS-regulated provenance chain; distinct lifecycle: instructed / delivered / superseded). Concept tier →

Attributes

This entity declares no module-local datatype properties. Valuation-specific facets (amount, model identifier, RICS classification etc.) are emitted via overlay profiles or via the inherited PROV-O qualified-attribution chain.

Relationships

This entity declares no module-local object properties. The class-promotion IC requires that each Valuation carries prov:wasGeneratedBy to its issuing activity (typically a RICS-regulated valuation Activity). Valuations may be informed by Comparable instances via prov:wasInformedBy.

Identity key

Identity key = prov:wasGeneratedBy to the issuing activity. The Activity carries the (valuer, timestamp, RICS-registration) tuple that disambiguates Valuation instances.

Constraints

  • Valuation MUST carry prov:wasGeneratedBy to its issuing activity per ODR-0008 §Q4a three-criterion test (Violation, ValuationIdentityKeyShape)

Derived attributes

None.

Lifecycle state-transition diagram

Valuation lifecycle per S008 Q4 — instructed, delivered (by the valuation Activity), and may be superseded by a later valuation.
