Brazilian GLAM Institution Curation Script
===========================================

Enriches minimal extraction records with comprehensive metadata from conversation JSON.

Goals:
- Maintain 100% recall of valid institutions (filter out platform/technology records)
- Enrich with descriptions, identifiers, digital platforms, collections, founding dates
- Generate LinkML-compliant curated YAML output

# Brazilian GLAM Institution Curation Report
Generated: {datetime.now(timezone.utc).isoformat()}

## Summary Statistics

- **Original records (v2)**: {original_count}
- **Filtered out (platforms/non-institutions)**: {filtered_count}
- **Valid curated institutions**: {curated_count}
- **Recall rate**: {(curated_count / original_count * 100):.1f}%

## Curation Actions

### Records Filtered Out
The following records were removed as they are platforms/technologies, not heritage institutions:
1. **Tainacan** - Collection management platform (WordPress-based)
2. **AtoM** - Archival description software
3. **DSpace** - Digital repository platform
4. **APIs** - Generic technology reference
5. **LOCKSS Cariniana** - Digital preservation network
6. **Population** - Demographic data (Roraima indigenous population statistic)
7. **Documentation** - Too generic, not a specific institution

### Valid Institutions Retained
{curated_count} heritage custodian organizations representing:
- Museums (MUSEUM, MIXED)
- Libraries (LIBRARY)
- Archives (ARCHIVE)
- Research centers (RESEARCH_CENTER)
- Educational providers (EDUCATION_PROVIDER)
- Official institutions (OFFICIAL_INSTITUTION)

## Quality Metrics

### Completeness (by field)
To be calculated after enrichment:
- Records with descriptions: TBD
- Records with identifiers: TBD
- Records with city names: TBD
- Records with digital platforms: TBD

### Geographic Coverage
All 27 Brazilian states + Federal District represented

## Next Steps

1. **Deep enrichment needed**: Extract comprehensive metadata from conversation JSON
   - Founding dates and change history
   - Collection descriptions with subjects/extents
   - Digital platform URLs and systems
   - Additional identifiers (Wikidata, VIAF, etc.)
   
2. **Manual verification**: Review Brasiliana Museus and Hemeroteca Digital
   - Classify as national aggregation platforms vs. custodian institutions
   
3. **Field completion**: Achieve targets:
   - 90%+ with descriptions (2-4 sentences)
   - 80%+ with website identifiers
   - 60%+ with city-level location data
