- Created the Country class with ISO 3166-1 alpha-2 and alpha-3 codes, ensuring minimal design without additional metadata. - Integrated the Country class into CustodianPlace and LegalForm schemas to support country-specific feature types and legal forms. - Removed duplicate keys in FeatureTypeEnum.yaml, resulting in 294 unique feature types. - Eliminated "Hypernyms:" text from FeatureTypeEnum descriptions, verifying that semantic relationships are now conveyed through ontology mappings. - Created example instance file demonstrating integration of Country with CustodianPlace and LegalForm. - Updated documentation to reflect the completion of the Country class implementation and hypernyms removal.

# Quick Status: Country Class Implementation (2025-11-22)
|
|
|
|
## ✅ COMPLETE
|
|
|
|
### What Was Done
|
|
|
|
1. **Fixed Duplicate Keys in FeatureTypeEnum.yaml**
|
|
- Removed 2 duplicate entries (RESIDENTIAL_BUILDING, SANCTUARY)
|
|
- 294 unique feature types (validated ✅)
|
|
|
|
2. **Created Country Class**
|
|
- File: `schemas/20251121/linkml/modules/classes/Country.yaml`
|
|
- Minimal design: ONLY ISO 3166-1 alpha-2 and alpha-3 codes
|
|
- No other metadata (names, languages, capitals)
|
|
|
|
3. **Integrated Country with CustodianPlace**
|
|
- Added optional `country` slot
|
|
- Enables country-specific feature type validation
|
|
|
|
4. **Integrated Country with LegalForm**
|
|
- Changed `country_code` from string to Country class
|
|
- Enforces jurisdiction-specific legal forms
|
|
|
|
5. **Created Example File**
|
|
- `schemas/20251121/examples/country_integration_example.yaml`
|
|
- Shows Country → CustodianPlace → FeaturePlace integration
|
|
|
|
### Country Class Schema
|
|
|
|
```yaml
|
|
Country:
|
|
slots:
|
|
- alpha_2 # ISO 3166-1 alpha-2 (NL, PE, US)
|
|
- alpha_3 # ISO 3166-1 alpha-3 (NLD, PER, USA)
|
|
```
|
|
|
|
**Examples**:
|
|
- Netherlands: `alpha_2="NL"`, `alpha_3="NLD"`
|
|
- Peru: `alpha_2="PE"`, `alpha_3="PER"`
|
|
|
|
### Use Cases
|
|
|
|
**Country-Specific Feature Types**:
|
|
- CULTURAL_HERITAGE_OF_PERU (Q16617058) → Only valid for `country.alpha_2 = "PE"`
|
|
- BUITENPLAATS (Q2927789) → Only valid for `country.alpha_2 = "NL"`
|
|
- NATIONAL_MEMORIAL_OF_THE_UNITED_STATES (Q20010800) → Only valid for `country.alpha_2 = "US"`
|
|
|
|
**Legal Form Jurisdiction**:
|
|
- Dutch Stichting (ELF 8888) → `country.alpha_2 = "NL"`
|
|
- German GmbH (ELF 8MBH) → `country.alpha_2 = "DE"`
|
|
|
|

|
|
|
|
## Next Steps (Future)
|
|
|
|
1. **Country-Conditional Enum Validation** - Validate feature types against country restrictions
|
|
2. **Populate Country Instances** - Create all 249 ISO 3166-1 countries
|
|
3. **Link LegalForm to ISO 20275** - Populate 1,600+ legal forms across 150+ jurisdictions
|
|
4. **External Metadata Resolution** - Integrate GeoNames API for country names/metadata
|
