Belarus ISIL Enrichment - Complete Session Summary

Date: November 18, 2025
Duration: ~2 hours
Objective: Extract, enrich, and document the complete Belarus ISIL registry with external metadata

Accomplishments

1. Data Collection ✅

ISIL Registry Extraction

  • Source: National Library of Belarus (https://nlb.by/)
  • Method: Web scraping via MCP tools (Exa search + WebFetch)
  • Result: 154 institutions with ISIL codes extracted
  • Coverage: All 7 administrative regions
    • Brest Region (BY-BR): 20 institutions
    • Vitebsk Region (BY-VI): 25 institutions
    • Gomel Region (BY-HO): 29 institutions
    • Grodno Region (BY-HR): 19 institutions

    • Minsk City (BY-HM): 25 institutions
    • Mogilev Region (BY-MA): 25 institutions

Output File: data/isil/belarus_isil_complete_dataset.md

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/
BY-HM0008 Presidential Library Q2091093 - http://preslib.org.by/
BY-HM0005 Yakub Kolas Central Scientific Library Q3918424 125518437 https://csl.bas-net.by/

BY-HR0000 Grodno Regional Library (Karsky) Q13030528 - http://grodnolib.by/

Candidates for Future Linking: 27 additional Wikidata entities without ISIL codes (requires fuzzy name matching)

OpenStreetMap Enrichment

Query: Overpass API query for Belarus library amenities
Results: 575 library locations in OpenStreetMap

Breakdown:

  • 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)

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:

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)

  1. 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

  2. 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

  3. 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)

  1. 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

  2. Regional Comparison

    • Compare Belarus ISIL coverage to neighboring countries
    • Poland, Lithuania, Latvia, Ukraine, Russia
    • Identify best practices and gaps
    • Deliverable: Regional ISIL analysis report

  3. 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
