## File Statistics

- **File Size**: 2.2 MB
- **Line Count**: 90,950 lines
- **Format**: YAML with UTF-8 encoding

## Usage

This file can be used for:

1. **Ontology mapping**: Understanding which Wikidata entities represent physical features
2. **Schema validation**: Ensuring FEATURES classification is correctly applied
3. **Geographic analysis**: Identifying heritage landscape features
4. **Data quality**: Cross-referencing with other heritage databases

## Schema Alignment

These entities should map to the following ontology classes in LinkML schema:

- **CIDOC-CRM**: `crm:E27_Site` (physical sites)
- **Schema.org**: `schema:Place`, `schema:LandmarksOrHistoricalBuildings`
- **RiC-O**: `rico:Place` (archival context)

## Next Steps

1. Map each Q-number to appropriate LinkML `class_uri`
2. Create `HeritageCustodian` records for institutions managing these features
3. Link physical features to custodian organizations via `manages_feature` relationship
4. Geocode locations for mapping visualization
