kempersc 1fb924c412 feat: add ontology mappings to LinkML schema and enhance entity resolution 
Schema enhancements (443 files):
- Add class_uri with proper ontology references (schema:, prov:, skos:, rico:)
- Add close_mappings, related_mappings per Rule 50 convention
- Replace stub hc: slot_uri with standard predicates (dcterms:identifier, skos:prefLabel)
- Improve descriptions with ontology mapping rationale
- Add prefixes blocks to all schema modules

Entity Resolution improvements:
- Add entity_resolution module with email semantics parsing
- Enhance build_entity_resolution.py with email-based matching signals
- Extend Entity Review API with filtering by signal types and count
- Add candidates caching and indexing for performance
- Add ReviewLoginPage component

New rules and documentation:
- Add Rule 51: No Hallucinated Ontology References
- Add .opencode/rules/no-hallucinated-ontology-references.md
- Add .opencode/rules/slot-ontology-mapping-reference.md
- Add adms.ttl and dqv.ttl ontology files

Frontend ontology support:
- Add RiC-O_1-1.rdf and schemaorg.owl to public/ontology

Usage in LinkML Schema

The Heritage Custodian Ontology (schemas/20251121/linkml/01_custodian_name_modular.yaml) references these ontologies for:

  1. PiCo (pico:) - Core observation/reconstruction pattern for persons and entities
  2. PROV-O (prov:) - Provenance tracking, activity chains
  3. SOSA/SSN (sosa:, ssn:) - IoT devices, sensors, beacons
  4. GeoNames (gn:) - Settlement and geographic feature references
  5. LCC (lcc-cr:, lcc-3166-1:, lcc-3166-2:) - Country and subdivision codes
  6. GLEIF (gleif-base:, gleif-L1:) - Legal entity identification
  7. SKOS (skos:) - Concept schemes, labels, hierarchies
  8. Schema.org (schema:) - Web semantics, social media profiles
  9. CIDOC-CRM (crm:) - Cultural heritage event modeling
  10. EDM (edm:) - Cultural heritage object aggregation

Notes

  • EDM required Wayback Machine due to Cloudflare protection on europeana.eu
  • PiCo version 2023-09-21 is the current release
  • LCC provides ISO 3166 and ISO 639 codes as RDF - essential for country/language modeling
  • SOSA/SSN is a W3C/OGC joint standard for sensor observations
  • GeoNames ontology v3.3 (2022-01-30) includes feature codes for settlements
