## ✅ What We Completed

### 1. Added 7 Dutch Government Organization Mappings
**File**: `schemas/20251121/linkml/01_custodian_name.yaml`

```yaml
# NEW TOOIont narrow_mappings:
- tooi:Samenwerkingsorganisatie  # Collaborative heritage platforms
- tooi:Ministerie  # National ministries
- tooi:Zbo  # Independent administrative bodies
- tooi:ZboOfZboCluster  # ZBO clusters
- tooi:RegionaalOpenbaarLichaam  # Regional public bodies
- tooi:Gemeente  # Municipalities (city archives)
- tooi:Provincie  # Provinces (provincial heritage)
```

### 2. Schema Statistics Update
| Metric | Before | After |
|--------|--------|-------|
| Total Ontology Mappings | 88 | **95** (+7) |
| Custodian Narrow Mappings | 20 | **27** (+7) |
| YAML Validation | ✅ | ✅ |

### 3. Documentation Updated

- ✅ `SESSION_SUMMARY_20251121_TOOIONT_INTEGRATION.md` - Complete session documentation

## 🎯 Why This Matters

**Dutch Heritage Governance Precision**:
- 🏛️ **Municipalities** (gemeenten) - City archives like Stadsarchief Amsterdam
- 🏛️ **Provinces** (provincies) - Provincial archives like Noord-Hollands Archief
- 🏛️ **Ministries** (ministeries) - National heritage policy (OCW)
- 🏛️ **ZBOs** - Independent cultural agencies (Rijksdienst voor het Cultureel Erfgoed)
- 🏛️ **Collaborative Platforms** - Multi-institutional heritage networks

**Before**: Generic `cpov:PublicOrganisation` for all Dutch institutions  
**After**: Precise government-level classification with TOOIont ✅

## 🚀 Next Steps (For Next Agent)

### High Priority
1. **Regenerate RDF files** from updated LinkML schema
   ```bash
   gen-owl -f ttl schemas/20251121/linkml/01_custodian_name.yaml > schemas/20251121/rdf/01_custodian_name.owl.ttl
   ```

2. **Create example instances** with TOOIont mappings:
   - Dutch municipality archive (tooi:Gemeente)
   - Provincial heritage service (tooi:Provincie)
   - ZBO cultural agency (tooi:Zbo)

3. **Update TypeDB schema** with TOOIont mappings

### Medium Priority
4. Consider integrating TOOIont organizational change events:
   - `tooi:Wijzigingsgebeurtenis` (change events)
   - `tooi:Samenvoeging` (mergers)
   - `tooi:Opheffing` (closures)
