## Warnings

### Minor Issues (Non-blocking)

3 institutions lack city name in location data (online-only resources):

1. **Heritage Gazetteer** - Digital gazetteer (no physical location)
2. **Temehu Online Museum** - Digital museum (online-only)
3. **Nafusa Libraries** - Network of libraries (no single city)

**Resolution**: Acceptable. These are digital/distributed resources without a single physical location.

## Next Steps

### Recommended Actions

1. ✅ **COMPLETE**: Validation passed
2. ⏳ **Geocoding**: Add lat/lon coordinates for 54 locations
3. ⏳ **Wikidata Enrichment**: Link institutions to Wikidata Q-numbers
4. ⏳ **Export**: Generate RDF, JSON-LD, GeoJSON formats
5. ⏳ **Integrate**: Merge with global dataset

### Data Enhancement Opportunities

- **Wikidata Linking**: 40 institutions have identifiers but only ~10 have Wikidata Q-numbers
- **Digital Platform URLs**: 17 platforms mentioned but only 7 have URLs
- **Collection Details**: 47 collections documented but extent/temporal coverage could be expanded
- **Geographic Precision**: Add specific addresses and coordinates where available
