Risk Assessment

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

An information artefact reporting the authority-retrieved result for one environmental or search peril against a property (its indicator, alert rating, result, summary, recommendations, and attribution), individuated by the tuple of generating activity, source peril/dataset, subject property, and generation time rather than by its result values.

Per-peril authority-retrieved search / environmental result (the six-field block riskIndicator / actionAlertRating / result / summary / recommendations / datasetAttribution recurring across the environmental perils and CON29-style local searches). UFO Information Object (a report — an information artefact existentially dependent on its generating activity; NOT a Substance Kind and NOT a Quality of opda:Property, ODR-0008d Rule 1a); PROV-O Entity. IC (Rule 1b): individuated by the tuple ⟨generating activity (prov:wasGeneratedBy), source peril/dataset, subject property, generation time (prov:generatedAtTime)⟩ — identity grounded in the activity, not the result values. Hard cases: a re-run search is a DISTINCT RiskAssessment (new activity + generatedAtTime), prov:wasDerivedFrom the prior; two providers' assessments for one property are distinct (distinct prov:wasAttributedTo); a riskSubcategories[] entry is itself a leaf RiskAssessment (opda:hasSubAssessment); otherEnvironmental is a valid leaf with optional Qualities absent. One class instantiated per peril, NOT 12 subclasses and NOT 72 datatype properties.
