Technical Issues Resolved

ID Mismatch Problem

Initial enrichment file (batch13_enriched.yaml) had incorrect institution IDs:

  • Issue: Used Q-numbers or numeric IDs instead of actual URL-format IDs
  • Example: Q108397863 instead of 709508309148680086
  • Resolution: Corrected IDs by searching main dataset for exact name matches

Corrected IDs

Institution Original ID (Wrong) Corrected ID Status
Secult Tocantins Q108397863 709508309148680086 ✅ Fixed
UNIR 3008281717687280329 3008281717687280329 ✅ Correct
Instituto Histórico Alagoas 2519599505258789521 2519599505258789521 ✅ Correct

Files Modified

Main Dataset

  • File: data/instances/all/globalglam-20251111.yaml
  • Backup: data/instances/all/globalglam-20251111.yaml.bak.batch13
  • Changes: Added 3 Wikidata identifiers + enrichment provenance

Enrichment Files

  • Corrected: data/instances/brazil/batch13_enriched.yaml (fixed Secretaria Tocantins ID)
  • Created: merge_batch13_corrected.py (merge script with corrected IDs)

Provenance Metadata

Each enriched institution received the following provenance entry:

enrichment_history:
  - enrichment_date: "2025-11-11T[timestamp]Z"
    enrichment_method: "Wikidata authenticated entity search (Batch 13)"
    enrichment_source: "batch13_enriched.yaml"
    fields_enriched: ['identifiers.Wikidata']
    wikidata_label: "[Wikidata label]"
    wikidata_description: "[Wikidata description]"

Next Steps

Immediate Actions

  1. ✅ COMPLETE: Merge 3 verified Q-numbers into main dataset
  2. ✅ COMPLETE: Create final report (this document)
  3. ⏳ TODO: Manually verify Q61000205 (Sistema Brasileiro de Museus)

Future Batches (Batch 14+)

  1. Add 4 bonus institutions found during searches (Museu Histórico Nacional, Museu Imperial, etc.)
  2. Create Wikidata items for 3 failed searches (if institutions are notable)
  3. Continue enrichment targeting 60-65% coverage (need +1-7 more institutions)

Recommendations

  • Prioritize major museums: Museu Histórico Nacional (Q510993) should be in dataset
  • Validate regional institutions: Check if failed searches are actual heritage institutions
  • Investigate SBM Q-number: Q61000205 needs manual Wikidata verification

Lessons Learned

  1. ID Verification Critical: Always verify institution IDs by searching the main dataset before creating enrichment files
  2. Numeric IDs Valid: Main dataset uses both URL-format and numeric IDs - both are valid
  3. Bonus Matches Value: Finding institutions not in target list (4 bonus matches) helps identify missing entries
  4. Regional Institutions Gap: Small regional museums often lack Wikidata entries - opportunity for contribution

Conclusion

Batch 13 successfully enriched 3 Brazilian institutions with Wikidata Q-numbers, achieving:

  • ✅ 59.5% Wikidata coverage (up from 57.0%)
  • ✅ 75% Wikidata search success rate
  • ✅ 4 additional candidate institutions identified
  • ✅ All technical ID issues resolved

Status: Ready for Batch 14 to continue toward 60-65% coverage target.
