# 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)
|
|
```yaml
|
|
provenance:
|
|
notes: "Wikidata enriched 2025-11-10 (Q3330723, match: 100%). Geocoded..."
|
|
```
|
|
- ❌ Unstructured text
|
|
- ❌ Not queryable
|
|
- ❌ No ontology alignment
|
|
|
|
### After (v0.2.2)
|
|
```yaml
|
|
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:
|
|
```bash
|
|
python scripts/demo_enrichment_history.py
|
|
```
|
|
|
|
Verify schema:
|
|
```bash
|
|
python -c "import yaml; schema = yaml.safe_load(open('schemas/heritage_custodian.yaml')); print(f'Version: {schema[\"version\"]}')"
|
|
```
|
|
|
|
Check enrichment types:
|
|
```bash
|
|
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
|
