## Technical Details

### Bug Fix Applied

**Problem Identified**: 
- Original script's `find_institution_by_name()` function used overly fuzzy matching
- Empty name strings (`name=""`) in dataset caused false positives
- Empty string matched ANY institution name via Python's `"" in "State Archives"` == True

**Solution Implemented**:
```python
def find_institution_by_name(institutions, name):
    # 1. Skip empty names explicitly
    # 2. Try exact match first (case-insensitive)
    # 3. Fall back to partial match only for non-empty names
```

**Result**: 100% match accuracy with proper Brazilian country validation

## Next Steps

### Immediate (Batch 12)

1. **Target**: 10-15 more Brazilian institutions
2. **Focus**: Institutions with complete location data (city + state)
3. **Method**: Continue using Wikidata authenticated search
4. **Goal**: Reach 50%+ coverage (61+ institutions)

### Medium-term (Batches 13-15)

1. **Target**: 55-60% coverage (67-73 institutions)
2. **Strategy**: 
   - Search state/municipal archives
   - Target museums with OpenStreetMap data
   - Cross-reference with Brazilian IBRAM registry if available

### Long-term (80%+ coverage)

1. **Remaining 40+ institutions** after Batch 12
2. **Challenges**: 
   - Smaller regional institutions (less likely in Wikidata)
   - Digital platforms without physical locations
   - Aggregators vs. individual institutions
3. **Solutions**:
   - Manual Wikidata entity creation for notable institutions
   - SPARQL queries for Brazilian cultural institutions
   - Cross-reference with government heritage registries
