|
### 2. External Enrichment ✅
|
|
|
|
#### Wikidata Enrichment
|
|
|
|
**Query**: SPARQL query for Belarusian libraries
|
|
**Results**: **32 Belarusian library entities found**
|
|
|
|
**Matched to ISIL Codes** (5 institutions):
|
|
|
|
| ISIL Code | Institution | Wikidata ID | VIAF | Website |
|
|
|-----------|-------------|-------------|------|---------|
|
|
| BY-HM0000 | National Library of Belarus | Q948470 | 163025395 | https://www.nlb.by/ |

|
- **8 entries** with Wikidata links (can be cross-referenced)
|
|
- **201 entries** with rich metadata (contact info, addresses, opening hours)
|
|
- **366 entries** with basic location data only
|
|
|
|

|
|
|
|
### 3. LinkML Dataset Creation ✅
|
|
|
|
**Output File**: `data/instances/belarus_isil_enriched.yaml`
|
|
|
|
**Schema Compliance**: LinkML heritage_custodian.yaml v0.2.1
|
|
**Records Created**: 10 (demonstration sample - top enriched institutions)
|
|
|
|
**Record Structure**:
|
|
```yaml
|
|

|
|
## Key Findings
|
|
|
|
### Registry Characteristics
|
|
|
|
1. **Minimal Metadata**: Unlike Swiss or Dutch ISIL registries, Belarus publishes only:
|
|
- ✅ ISIL codes
|
|
- ✅ Institution names
|
|
- ❌ No addresses
|
|
- ❌ No contact information (phone, email, website)
|
|
- ❌ No coordinates
|
|
- ❌ No dates assigned
|
|
- ❌ No parent organizations
|
|
|
|
2. **Hierarchical Structure**: Regional libraries use `0000` codes (e.g., `BY-BR0000`, `BY-VI0000`), establishing clear hierarchy
|
|
|
|
3. **Non-Sequential Numbering**: Some gaps exist (e.g., `BY-HM0016`, `BY-HM0019` - missing 0017, 0018), suggesting reserved or unlisted codes
|
|
|
|
4. **Centralized System**: Most institutions are district/regional centralized library systems under government administration
|
|
|

|
|
|
|
### Enrichment Success
|
|
|
|
**Enrichment Rate by Source**:
|
|
- **Wikidata**: 5/154 (3.2%) matched via ISIL or name
|
|
- 27 additional candidates require fuzzy matching
|
|
- **OpenStreetMap**:
|
|
- 8/154 (5.2%) with Wikidata cross-reference
|
|
- 201/575 OSM entries with contact metadata (potential matches)
|
|
|
|
**Geographic Coverage**:
|
|
- All 7 regions represented
|
|
- Minsk City has highest concentration (25 institutions)
|
|
- Rural districts underrepresented in enrichment sources
|
|
|
|
**Data Completeness**:
|
|
| Field | ISIL Registry | +Wikidata | +OSM | Final |
|

|
## Challenges & Limitations
|
|
|
|
### Data Quality Issues
|
|
|
|
1. **Name Variation**: Institution names vary across sources
|
|
- ISIL: "Central Scientific Library named after Yakub Kolas"
|
|
- Wikidata: "Yakub Kolas Central Scientific Library"
|
|
- OSM: "Цэнтральная навуковая бібліятэка імя Якуба Коласа" (Belarusian)
|
|
- **Solution**: Fuzzy string matching required (e.g., rapidfuzz)
|
|
|
|
2. **Language Barriers**:
|
|
- ISIL registry: English (transliterated names)
|
|
- OSM: Belarusian/Russian
|
|
- Wikidata: Multilingual labels
|
|
- **Solution**: Cross-language entity resolution via Wikidata
|
|
|
|
3. **OSM Completeness**:
|
|
- 575 OSM library entries > 154 ISIL codes
|
|
- Many OSM entries are branch libraries, school libraries, or unofficial collections
|
|
- **Solution**: Filter by institution type and administrative level
|
|
|
|
4. **Missing Identifiers**:
|
|
- Only 1 ISIL code in Wikidata (BY-HM0000)
|
|
- Most Wikidata library entities lack ISIL properties
|
|
- **Solution**: Contribute ISIL codes back to Wikidata
|
|
|
|
---
|
|
|
|
### Technical Limitations
|
|
|
|
1. **API Rate Limits**:
|
|
- Wikidata SPARQL: No authentication, subject to query timeout
|
|
- Overpass API: 60-second timeout, may fail for large queries
|
|
- **Mitigation**: Caching, query optimization
|
|
|
|
2. **Geocoding Accuracy**:
|
|
- OSM coordinates are crowd-sourced, may have errors
|
|
- No validation against authoritative sources
|
|
- **Solution**: Cross-check with multiple sources when available
|
|
|
|
3. **Schema Compliance**:
|
|
- Sample LinkML dataset (10 records) created for demonstration
|
|
- Full 154-record dataset requires batch processing
|
|
- **Solution**: Automate record generation with validation
|
|

## Next Steps
|
|
|
|
### Immediate (Required for Completion)
|
|
|
|
1. **Fuzzy Matching** 🔴 HIGH PRIORITY
|
|
- Match remaining 149 ISIL institutions to OSM/Wikidata
|
|
- Use `rapidfuzz` library for name similarity
|
|
- Threshold: >85% match confidence
|
|
- **Estimated effort**: 2-3 hours
|
|
|
|
2. **Full LinkML Dataset** 🔴 HIGH PRIORITY
|
|
- Generate all 154 institutions in LinkML YAML format
|
|
- Include enriched metadata where available
|
|
- Validate against schema v0.2.1
|
|
- **Output**: `data/instances/belarus_complete.yaml`
|
|
|
|
3. **RDF/JSON-LD Export** 🟡 MEDIUM PRIORITY
|
|
- Convert LinkML YAML to RDF Turtle
|
|
- Generate JSON-LD context
|
|
- Export for Linked Open Data consumption
|
|
- **Tools**: `linkml-convert`
|
|
|
|
---
|
|
|
|
### Short-Term (1-2 Weeks)
|
|
|
|
4. **Manual Verification** 🟡 MEDIUM PRIORITY
|
|
- Spot-check top 20 enriched institutions
|
|
- Verify coordinates by visiting institutional websites
|
|
- Correct any mismatches or errors
|
|
- **Target**: 95%+ accuracy for enriched records
|
|
|
|
5. **Wikidata Contribution** 🟢 LOW PRIORITY
|
|
- Add ISIL codes to Wikidata entities (P791 property)
|
|
- Improve Belarusian library coverage in Wikidata
|
|
- Requires Wikidata account + familiarity with editing
|
|
- **Impact**: Benefits entire LOD community
|
|
|
|
6. **Contact Registry Authority** 🟢 LOW PRIORITY
|
|
- Email National Library of Belarus (inbox@nlb.by)
|
|
- Request full metadata export (addresses, contacts, dates)
|
|
- Propose collaboration on enrichment
|
|
- **Outcome**: Potential TIER_1 enrichment
|
|
|
|
---
|
|
|
|
### Long-Term (1+ Months)
|
|
|
|
7. **Expand to Archives & Museums**
|
|
- Belarus ISIL currently covers libraries only
|
|
- Identify candidates for ISIL assignment
|
|
- Cross-reference with archival/museum databases
|
|
- **Resources**: Check Russian archives registry, museum associations
|
|
|
|
8. **Regional Comparison**
|
|
- Compare Belarus ISIL coverage to neighboring countries
|
|
- Poland, Lithuania, Latvia, Ukraine, Russia
|
|
- Identify best practices and gaps
|
|
- **Deliverable**: Regional ISIL analysis report
|
|
|
|
9. **Integration with GLAM Project**
|
|
- Merge Belarus data into global GLAM database
|
|
- Apply GHCID identifier scheme
|
|
- Link to conversation extraction pipeline
|
|
- **File**: Update `data/instances/europe/belarus/*.yaml`
|
