## To Resume Work

### Option 1: Scale to Full Dataset

```bash
cd /Users/kempersc/apps/glam
python3 scripts/enrich_nde_with_wikidata.py --start-index 10 --batch-size 50
```

**Expected**:
- Processing time: 2-3 hours
- Success rate: 70-85% (based on test batch)
- ~950-1,150 organizations will get Wikidata IDs

### Option 2: Check Current Status

```bash
python3 -c "
import yaml
with open('data/nde/voorbeeld_lijst_organisaties_en_diensten-totaallijst_nederland.yaml', 'r') as f:
    orgs = yaml.safe_load(f)
enriched = len([o for o in orgs if 'wikidata_id' in o])
print(f'Enriched: {enriched}/{len(orgs)} ({enriched/len(orgs)*100:.1f}%)')
"
```

### Option 3: Validate Enrichment

```bash
# Check for duplicates and verify Q-numbers
python3 scripts/validate_wikidata_enrichment.py
```

---

## Key Commands

### Search Wikidata Entity
```python
from wikidata_mcp import search_entity
q_number = search_entity("Rijksmuseum Amsterdam")
# Returns: Q190804
```

### Verify Q-Number
```python
from wikidata_mcp import get_metadata
metadata = get_metadata("Q190804", language="nl")
# Returns: {"Label": "Rijksmuseum", "Description": "museum in Amsterdam"}
```

### SPARQL Query (for municipalities)
```sparql
SELECT ?item ?itemLabel WHERE {
  ?item wdt:P31 wd:Q2039348 .  # Dutch municipality
  ?item rdfs:label "Amsterdam"@nl .
  SERVICE wikibase:label { bd:serviceParam wikibase:language "nl,en". }
}
```

## Success Patterns

✅ **Museums with national/international recognition**: 100% match  
✅ **Municipal archives**: 100% match (use municipality Q-number)  
✅ **Regional archives**: 100% match  
⚠️ **Branch locations**: Low coverage (often not in Wikidata)  
⚠️ **Inter-municipal partnerships**: Low coverage  
⚠️ **Small local societies**: Varies (50-70% expected)

---

## Next Milestones

1. **First 100 records** enriched → Review success rate, adjust strategy
2. **First 500 records** enriched → Identify patterns in no-matches
3. **First 1,000 records** enriched → Statistical analysis
4. **All 1,351 records** processed → Final report and integration

---

## Important Notes

- **Rate limit**: 1,000 requests/hour (Wikidata API)
- **Batch size**: 50 records per batch (recommended)
- **Verification**: Always verify Q-numbers with `get_metadata`
- **Backup**: Created before enrichment (`.backup.*.yaml`)
- **Logging**: All queries logged in `/data/nde/sparql/`

---

## Questions to Address

1. Should we create Wikidata entries for missing institutions?
2. How to handle branch locations (link to parent or omit)?
3. Manual review threshold (currently 85% confidence)?
4. When to integrate with main GLAM project schema?
