    UFO meta-category

    Information Object

    12 classes classified under the UFO foundational meta-category Information Object — from the inert opda:ufoCategory facet (an annotation-graph-only documentary annotation; UFO-informed, not UFO-grounded). The classification doctrine keeps kinds as facets, not subclass trees (ODR-0027).

    ClassDefinition (rdfs:comment)
    opda:AttachedDocument A document attached to a transaction record (e.g. the registry additionalDocuments[] filed against a title to be sold). UFO Information Object; PROV-O Entity. A NEUTRAL document Kind — NOT evidence: it bears filing metadata (opda:documentDate / opda:documentTypeCode / opda:filedUnder / opda:retrievedOn) without the eIDAS-assurance commitment a document playing the evidence role carries (ODR-0024 R7 / session-028 Q7 — entailing every attached doc is Substantial-tier evidence). IC: individuated by its content + issuing activity (the artefact the registry holds), NOT by documentTypeCode / documentDate (mutable descriptive facets, not an identity principle). A document BECOMES evidence by playing the evidence role — recorded as opda:evidenceType 'Document' on an opda:Evidence (ODR-0027 §R6), NOT by an rdfs:subClassOf into evidence; an attached document stands as evidence only under ODR-0009, never by mere attachment.
    opda:Claim Verifiable claim entity. UFO Information particular; PROV-O Entity. Per S009 Q1 80%-PROV-O mapping. Hard cases: contested assertion (multiple verifications with divergent verdicts); multi-method verification (electronic-record + vouch corroboration); assurance-level downgrade (vouch-only evidence caps at eIDAS Low).
    opda:Comparable No DPV class-level baseline; PII coverage flows transitively via the linked opda:Property (which carries the postal-address baseline). Per ODR-0018 §Rule 1: only direct PII-bearing Kinds declare a baseline; transitively-linked Kinds do not duplicate the upstream baseline.
    opda:DPVMappingRecord Mapping record from an OPDA Kind class to its DPV baseline personal-data category and optional variant-conditional refinements. UFO Information Particular. Per ODR-0018 §Rule 4 + ODR-0012 §Evidence co-annotation, ODR-0012 is the authoring authority — this module emits the mapping records; ADR-0012 emits the resulting DPV co-annotation triples into opda-annotations.ttl (three-graph separation).
    opda:EPCCertificate Energy Performance Certificate — DESNZ-governed authority-retrieved artefact. UFO Information Object (a certificate is an information artefact, NOT a Substance Kind, per ODR-0008d Rule 3 A9 retro-correction); PROV-O Entity. Class-promoted per S008 Q4 three-criterion test: authority-retrieved provenance (DESNZ register); distinct lifecycle (10-year validity; supersession on re-assessment); distinct PII regime per ODR-0018 (address + owner-identifiable).
    opda:GeneratorRun Information particular. IC: a single execution of the opda-gen pipeline that produced a specific set of emitted TTL artefacts. Carries the generator version (opda-gen-<semver>), the source commit SHA, and the emission timestamp. Per ODR-0004 §6a, every emission is reproducible from the recorded (version, commit) pair.
    opda:LeaseTerm OWL-Time ProperInterval representing a leasehold term. Carries time:hasBeginning + time:hasDurationDescription (or time:hasEnd) per S007 Q5. Belongs to opda:LegalEstate of leasehold tenure (opda:leaseTerm join predicate). Modified by opda:LeaseExtensionEvent on statutory extension — extension produces a successor LeaseTerm with prov:wasDerivedFrom chain.
    opda:RiskAssessment 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.
    opda:Search No DPV class-level baseline; PII coverage flows transitively via the linked opda:Property (which carries the postal-address baseline). Per ODR-0018 §Rule 1: only direct PII-bearing Kinds declare a baseline; transitively-linked Kinds do not duplicate the upstream baseline.
    opda:Survey No DPV class-level baseline; PII coverage flows transitively via the linked opda:Property (which carries the postal-address baseline). Per ODR-0018 §Rule 1: only direct PII-bearing Kinds declare a baseline; transitively-linked Kinds do not duplicate the upstream baseline.
    opda:TrustFramework Trust framework citation — a governance regime that scopes claim validity (e.g. the UK Property Data Trust Framework). Per S009 5-residue mapped to dct:conformsTo on the verification activity (NOT a PROV-O primitive). Authoritative within scope per Session 003c Item 3 (OPDA TF authoritative scope).
    opda:Valuation No DPV class-level baseline; PII coverage flows transitively via the linked opda:Property (which carries the postal-address baseline). Per ODR-0018 §Rule 1: only direct PII-bearing Kinds declare a baseline; transitively-linked Kinds do not duplicate the upstream baseline.
