## What We Did
|
|
|

### Merged Enriched Datasets into Master Database
|
|
|
|
Successfully merged enriched data from Tunisia and Georgia back into the authoritative master dataset:
|
|

## Merge Strategy Details
|
|
|
|
### Enrichment Comparison Logic
|
|
|
|
The merge script uses `is_more_enriched()` function to determine which version to keep:
|
|
|
|
1. **Wikidata presence** - Prioritize records with Wikidata identifiers
|
|
2. **Enrichment history** - Prefer records with documented enrichment provenance
|
|
3. **Identifier count** - Choose records with more external identifiers
|
|
4. **Default behavior** - Keep existing record if enrichment levels are equal
|
|
|
|
### Deduplication Key
|
|
|
|
Institutions matched by priority:
|
|
1. **Primary**: `id` field (W3C Heritage Custodian URI)
|
|
2. **Secondary**: `ghcid` (Global Heritage Custodian ID)
|
|
3. **Fallback**: `name + country` combination
|
|
|
|
### File Format Handling
|
|
|
|
Script handles both YAML formats:
|
|
- **Plain list**: `[institution1, institution2, ...]`
|
|
- **Metadata wrapper**: `{_metadata: {...}, institutions: [...]}`
|
|
|
|
## Data Quality Observations
|
|
|
|
### Tunisia Enrichment Quality
|
|
- **High Wikidata coverage**: 52/68 institutions (76.5%)
|
|
- **Geographic coverage**: Tunis (capital) + 20+ regional cities
|
|
- **Institution diversity**: Libraries, archives, museums, universities, cultural centers
|
|
- **Temporal depth**: Ancient sites (Carthage, Dougga) + modern institutions
|
|
|
|
### Georgia Enrichment Quality
|
|
- **Very high Wikidata coverage**: 12/14 institutions (85.7%)
|
|
- **Geographic focus**: Primarily Tbilisi (capital)
|
|
- **Institution concentration**: National-level heritage custodians
|
|
- **Collection significance**: 3.9M+ items in National Library alone
|
|
|
|
### Why Some Were Skipped (19 total)
|
|
|
|
**Tunisia (18 skipped)**:
|
|
- Already had equivalent or better enrichment in master dataset
|
|
- Likely enriched in previous merge operations
|
|
- No data quality loss by preserving existing records
|
|
|
|
**Georgia (1 skipped)**:
|
|
- One institution already had equal enrichment level
|
|
- Existing record retained for PID stability
|
|
|
|
## Next Steps
|
|
|
|
### Immediate (Recommended)
|
|
1. **Update DATASET_STATISTICS.yaml** with new Wikidata coverage (56.1%)
|
|
2. **Verify merge quality** - Spot-check sample of 63 replaced institutions
|
|
3. **Archive old backup** - Move pre-merge backup to archive directory after verification
|
|
|
|
### Medium Priority
|
|
4. **Continue Latin America enrichment** - Brazil, Chile, Mexico batch processing
|
|
5. **Phase 2 country enrichment** - Belgium, Luxembourg, UK batches
|
|
|
|
### Future Merge Operations
|
|
6. Use updated `merge_enriched_to_global.py` script for future enrichment merges
|
|
7. Monitor Wikidata coverage trend (target: 70% by end of Phase 2)
|
|
|
|
## Technical Notes
|
|
|
|
### Merge Performance
|
|
- **Total processing time**: ~30 seconds for 82 enriched institutions
|
|
- **Memory usage**: Handled 13,502-institution YAML file without issues
|
|
- **No errors**: Clean merge with full success
|
|
|
|
### Backup Strategy
|
|
- Timestamped backups created automatically before each merge
|
|
- Format: `globalglam-20251111_backup_YYYYMMDD_HHMMSS.yaml`
|
|
- Retention: Keep until next merge confirms data integrity
|
|
|
|
### Script Robustness
|
|
- Handles exceptions gracefully (try/except on per-file basis)
|
|
- Preserves data on error (merge continues with remaining files)
|
|
- Detailed logging for audit trail
|
|
|
|
