Country names, languages, capitals, and other metadata should be resolved via external services (GeoNames, UN M49) to keep the ontology focused on heritage relationships, not geopolitical data. + +**Impact**: Country class only contains `alpha_2` and `alpha_3` slots. No names, no languages, no capitals. + +### **Decision 2: Use ISO 3166-2 for Subregions** + +✅ **Rationale**: ISO 3166-2 provides standardized subdivision codes used globally. Format `{country}-{subdivision}` (e.g., "US-PA") is unambiguous and widely adopted in government registries, GeoNames, etc. + +**Impact**: Handles regional restrictions (e.g., "Bali-specific shrines" = ID-BA, "Pennsylvania designations" = US-PA) + +### **Decision 3: GeoNames for Settlements** + +✅ **Rationale**: GeoNames provides stable numeric identifiers for settlements worldwide, resolving ambiguity from duplicate city names (e.g., 41 "Springfield"s in USA). + +**Impact**: Settlement class uses `geonames_id` as primary identifier, with `settlement_name` as human-readable fallback. + +### **Decision 4: Use dcterms:spatial for Country Restrictions** + +✅ **Rationale**: `dcterms:spatial` (Dublin Core) is a W3C standard property explicitly covering "jurisdiction under which the resource is relevant." Already used in DBpedia for geographic restrictions. + +**Impact**: FeatureTypeEnum permissible values get `dcterms:spatial` annotation for validation. + +### **Decision 5: Handle Historical Entities** + +✅ **Rationale**: Some Wikidata entries reference historical countries (Soviet Union, Czechoslovakia, Byzantine Empire, Japanese Empire). These need special ISO codes. + +**Implementation**: +```python +COUNTRY_NAME_TO_ISO = { + "Soviet Union": "HIST-SU", + "Czechoslovakia": "HIST-CS", + "Byzantine Empire": "HIST-BYZ", + "Japanese Empire": "HIST-JP", +} +``` + +--- + +## 🚀 Next Steps + +### **Phase 2: Schema Integration** (30-45 min) + +1. ✅ **Fix FeatureTypeEnum duplicate keys** (if needed) + -

Adds `dcterms:spatial`, `iso_3166_2`, `geonames_id` to 72 enum entries + - Preserves existing ontology mappings and descriptions + +3. ⏳ **Add geographic slots to CustodianLegalStatus** + - **Current**: `CustodianLegalStatus` has indirect country via `LegalForm.country_code` + - **Proposed**: Add direct `country`, `subregion`, `settlement` slots + - **Rationale**: Legal entities are jurisdiction-specific (e.g., Dutch stichting can only exist in NL) + +4. ⏳ **Import Subregion and Settlement classes into main schema** + -
