# Session Summary: Mexican Dataset Reconciliation
|
|
**Date**: November 13, 2025
|
|
**Session**: Mexican Dataset Reconciliation and Wikidata Cleanup
|
|
|
|
## Overview
|
|
|
|
Successfully reconciled the standalone Mexican dataset with the global unified dataset, corrected Wikidata identifiers, and documented the relationship between both files.
|
|
|
|
---
|
|
|
|
## Key Accomplishments
|
|
|
|
### 1. ✅ Dataset Structure Clarified
|
|
|
|
**Discovery**: The "global deduplicated" file is **NOT** Mexican-only - it contains **13,333 institutions from ALL countries** unified on November 11, 2025.
|
|
|
|
**Files**:
|
|
- **Standalone**: `data/instances/mexico/mexican_institutions_geocoded.yaml` (117 institutions, 8.5% Wikidata)
|
|
- **Global**: `data/instances/all/globalglam-20251113-mexico-deduplicated.yaml` (13,333 total, 108 Mexican)
|
|
- **Production dataset**: Mexican subset extracted from global file = **108 institutions with 50.9% Wikidata coverage**
|
|
|
|
### 2. ✅ Wikidata Identifier Corrections
|
|
|
|
| Institution | Issue | Resolution |
|
|
|------------|-------|------------|
|
|
| **Fototeca Nacional** | Had wrong Wikidata ID (Q5411481 = Fonoteca, not Fototeca) | ✅ Corrected to Q66432183 |
|
|
| **Instituto Nacional de Antropología e Historia (INAH)** | Missing Wikidata ID | ✅ Added Q901361 |
|
|
| **Fonoteca Nacional** | Duplicate entries | ✅ Merged duplicates, ensured Q5411481 present |
|
|
|
|
### 3. ✅ Reconciliation Analysis
|
|
|
|
**8 institutions in standalone but NOT in global**:
|
|
1. CLACSO Virtual Libraries
|
|
2. HathiTrust Digital Library
|
|
3. Internet Archive
|
|
4. Latin American Network Information Center (LANIC)
|
|
5. Library of Congress Hispanic Reading Room
|
|
6. Nettie Lee Benson Collection (UT Austin)
|
|
7. WorldCat Registry
|
|
8. WorldCat.org
|
|
|
|
**Analysis**: All 8 are **non-Mexican international digital platforms** - correctly filtered out during unification as they're not Mexican heritage custodians.
|
|
|
|
**Recommendation**: ✅ No action needed - filtering was appropriate.
|
|
|
|
### 4. ✅ Dramatic Wikidata Enrichment
|
|
|
|
- **Standalone**: 10 Wikidata IDs (8.5%)
|
|
- **Global Mexican subset**: 55 Wikidata IDs (50.9%)
|
|
- **Net gain**: +45 Wikidata identifiers during November 11-13 unification
|
|
|
|
**Enrichment occurred through**:
|
|
- Wikidata SPARQL queries
|
|
- Fuzzy name matching
|
|
- Manual verification
|
|
- 23 institutions have enrichment_history records
|
|

## Key Insights
|
|
|
|
### Data Quality Issues Identified
|
|
|
|
1. **Geographic data inconsistency**:
|
|
- 25 institutions (23.1%) have "Unknown" city
|
|
- "Mexico City" vs "Ciudad de México" duplication (should be normalized)
|
|
|
|
2. **Wikidata gap**:
|
|
- 53 institutions (49.1%) still lack Wikidata identifiers
|
|
- Opportunity for continued enrichment
|
|
|
|
3. **Standalone vs Global relationship**:
|
|
- Standalone file is **historical artifact** from earlier extraction
|
|
- **Global file is now authoritative** production dataset
|
|
- Standalone should be archived with clear documentation
|

## Recommendations for Next Session
|
|
|
|
### 🎯 Priority Actions
|
|
|
|
1. **Normalize city names**
|
|
- Merge "Mexico City" + "Ciudad de México" entries
|
|
- Resolve 25 "Unknown" city entries
|
|
|
|
2. **Continue Wikidata enrichment**
|
|
- Target 53 institutions without Wikidata IDs
|
|
- Use SPARQL queries for Mexican museums/archives/libraries
|
|
- Focus on major institutions first (MUNAL, Casa de la Benemérita Universidad Autónoma de Puebla, etc.)
|
|
|
|
3. **Update documentation**
|
|
- Revise `reports/mexico/baseline_analysis.md` to reference global dataset
|
|
- Document standalone → global migration
|
|
- Create enrichment plan for remaining 53 institutions
|
|
|
|
4. **Archive standalone dataset**
|
|
- Move `mexican_institutions_geocoded.yaml` to `/archive` folder
|
|
- Add README explaining it's superseded by global file
|
|
- Document relationship between files
|
|
|
|
### 📊 Optional: Advanced Analytics
|
|
|
|
- **Cross-reference with Mexican government heritage registries** (INAH catalogs, etc.)
|
|
- **Validate institution types** (some MIXED institutions may have clearer primary types)
|
|
- **Geocoding improvement** (resolve "Unknown" cities using address data)
|
|

## Technical Notes
|
|
|
|
### Python Scripts Used
|
|
|
|
All reconciliation performed with inline Python scripts using:
|
|
- `yaml` library for data loading/saving
|
|
- `datetime` for provenance timestamps
|
|
- Dictionary/set operations for comparison
|
|
- Counter for statistics
|
|
|
|
### Wikidata Verification
|
|
|
|
Used Wikidata MCP server to verify Q-numbers:
|
|
- **Q66432183**: Fototeca Nacional (photo archive) ✅
|
|
- **Q5411481**: Fonoteca Nacional (sound library) ✅
|
|
- **Q901361**: INAH (Instituto Nacional de Antropología e Historia) ✅
|
|

|
## Questions for User (if needed)
|
|
|
|
1. Should we proceed with **city name normalization** (Mexico City standardization)?
|
|
2. Priority for **Wikidata enrichment** - focus on specific institution types?
|
|
3. Should **standalone file be archived** now or kept for reference?
|
|
