## Enrichment Methodology

### Data Sources
1. **Wikidata SPARQL Endpoint** - Primary identifier verification
2. **VIAF API** - Cross-reference for institutional identifiers
3. **ISIL Registry** - International library/archive codes
4. **Institutional Websites** - Verification of official URLs

### Verification Process
For each institution:
1. ✅ SPARQL query to Wikidata using institution name + location
2. ✅ Fuzzy matching with threshold > 0.85
3. ✅ VIAF cross-reference where available
4. ✅ Website verification against Wikidata properties
5. ✅ Manual review of match quality

### Confidence Scoring
- **0.98 (High):** Wikidata + VIAF match + website verification (4 institutions)
- **0.95 (Very Good):** Wikidata match + type/location verification (2 institutions)

---

## Technical Implementation

### Script
- **File:** `scripts/enrich_mexico_batch01.py`
- **Method:** Direct YAML manipulation with PyYAML
- **Identifiers Added:**
  - Wikidata: Q-numbers with URLs
  - VIAF: Numeric IDs with URLs
  - ISIL: International codes with URLs

### Provenance Tracking
Each enriched institution received:
```yaml
provenance:
  enrichment_history:
    - enrichment_date: "2025-11-12T..."
      enrichment_method: "Wikidata SPARQL query + VIAF cross-reference"
      identifiers_added: ["Wikidata:Qxxxxxx", "VIAF:xxxxxxx"]
      confidence_score: 0.95-0.98
      notes: "Verified via SPARQL query and VIAF match"
```

### File Modified
- **Path:** `data/instances/mexico/mexican_institutions_geocoded.yaml`
- **Size:** 117 institutions
- **Lines modified:** 6 institution records updated

## Next Steps: Batch 2 Planning

### Candidate Institutions (Regional Museums)
Based on baseline analysis, Batch 2 should target regional museums with high Wikidata match probability:

**Priority 2 Candidates (15-20 institutions):**
1. Regional INAH museums (Museo Regional de X)
2. State museums with established Wikipedia presence
3. University museums (UNAM system)
4. Major city museums (Guadalajara, Monterrey, Puebla)

**Target Coverage:** 20-25% (24-29 institutions)

### Recommended Workflow
1. **Query Wikidata** for Mexican museums by geographic region
2. **Fuzzy match** against 111 remaining institutions
3. **Verify** top 20 matches with confidence > 0.85
4. **Add identifiers** using same methodology as Batch 1
5. **Document** in `batch02_report.md`
