## 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
11. **ORE** (`ore:`) - Object aggregation patterns
