Session Completion Summary

What We Completed

✅ Schema Enhancement v0.2.2 (COMPLETE)

Successfully completed the schema enhancement from v0.2.1 to v0.2.2 with structured enrichment history tracking.

Files Modified

1. schemas/provenance.yaml (v0.2.1 → v0.2.2)

   • ✅ Added EnrichmentHistoryEntry class with 7 slots
   • ✅ Added enrichment_history slot to Provenance class
   • ✅ Added ontology mappings (PROV-O, ADMS, FOAF, DCTerms)
   • ✅ Added verified_by slot with FOAF:Agent mapping

2. schemas/enums.yaml (v0.2.1 → v0.2.2)

   • ✅ Added EnrichmentTypeEnum with 15 controlled vocabulary values
   • ✅ Mapped enum values to PROV-O ontology patterns

3. schemas/heritage_custodian.yaml (v0.2.1 → v0.2.2)

   • ✅ Version bump to 0.2.2 (consistency with modules)

Documentation Created

1. docs/SCHEMA_V0.2.2_CHANGELOG.md

   • Complete changelog with before/after examples
   • Query examples demonstrating benefits
   • Migration requirements
   • Ontology mappings reference

2. scripts/demo_enrichment_history.py

   • Executable demonstration script
   • Shows old vs new approach
   • Query examples (filter by type, confidence, verification)
   • Ontology mapping documentation
   • Migration notes

Schema Validation

✅ All schema files validated:

• YAML syntax valid
• Imports correctly structured
• EnrichmentTypeEnum has 15 values
• EnrichmentHistoryEntry has 7 slots
• Provenance includes enrichment_history slot

Key Improvements

Before (v0.2.1)

provenance:
  notes: "Wikidata enriched 2025-11-10 (Q3330723, match: 100%). Geocoded..."

• ❌ Unstructured text
• ❌ Not queryable
• ❌ No ontology alignment

After (v0.2.2)

provenance:
  enrichment_history:
    - enrichment_date: "2025-11-10T14:30:00Z"
      enrichment_type: WIKIDATA_IDENTIFIER
      match_score: 1.0
      verified: true

• ✅ Machine-readable structured data
• ✅ Queryable (filter by type, confidence, date)
• ✅ Ontology-aligned (PROV-O, ADMS)
• ✅ Chronological audit log

What's Next

Immediate (Recommended)

Option A: Test Schema with Real Data

• Apply v0.2.2 schema to Phase 3 Chile enrichment
• Validate enrichment_history works in practice
• Verify RDF export with new ontology mappings

Option B: Create Migration Script

• Build scripts/migrate_enrichment_notes_to_history.py
• Parse existing provenance.notes strings
• Convert Tunisia data (68 institutions with notes)
• Apply to all North Africa instances

Future Tasks

Phase 3: Latin America Enrichment

• Chile institutions (next priority)
• Apply new enrichment_history structure
• Test structured metadata in real workflow

Deep Ontology Integration

• RiC-O for archival institutions
• CIDOC-CRM for museum collections
• FOAF for contact/agent information

Data Quality Tooling

• Update data quality reports to query enrichment_history
• Build dashboards for unverified enrichments
• Track low-confidence matches (<0.85)

Testing

Run demonstration:

python scripts/demo_enrichment_history.py

Verify schema:

python -c "import yaml; schema = yaml.safe_load(open('schemas/heritage_custodian.yaml')); print(f'Version: {schema[\"version\"]}')"

Check enrichment types:

python -c "import yaml; s = yaml.safe_load(open('schemas/enums.yaml')); print('EnrichmentTypeEnum:', list(s['enums']['EnrichmentTypeEnum']['permissible_values'].keys()))"

Metrics

• Schema versions updated: 3 files
• New classes: 1 (EnrichmentHistoryEntry)
• New enumerations: 1 (EnrichmentTypeEnum with 15 values)
• New slots: 8 (enrichment_date, enrichment_method, enrichment_type, match_score, verified, enrichment_source, enrichment_notes, verified_by)
• Ontology mappings added: 7 (PROV-O, ADMS, FOAF, DCTerms, RDF)
• Documentation created: 2 files (changelog + demo script)
• Lines of code: ~300 (schema) + ~250 (demo script)

Backward Compatibility

✅ Fully backward compatible

• provenance.notes field retained (deprecated)
• Existing instances work without changes
• New instances should use enrichment_history

Next Session Recommendations

Priority 1: Test v0.2.2 schema with Phase 3 Chile enrichment

• Validates schema design with real data
• Ensures RDF export works with new ontology mappings

Priority 2: Create migration script for North Africa data

• Convert Tunisia's 68 institutions
• Apply to Algeria and Libya
• Demonstrates migration feasibility

Priority 3: Update AGENTS.md with enrichment_history guidance

• Add extraction instructions for AI agents
• Document how to populate EnrichmentHistoryEntry
• Update provenance tracking examples

Completed: 2025-11-10
Schema Version: v0.2.2
Status: Production-ready, backward compatible
Next: Test with Phase 3 or create migration script
