🏆 Data Quality Assessment

Strengths

Comprehensive Coverage: All 8,145 Czech GLAM institutions
Rich Metadata: GPS coordinates, opening hours, collection stats
Well-Structured: Hierarchical organization (main/departments/branches)
Multilingual: Czech and English name variants
Up-to-Date: Weekly refresh cycle
Open License: CC0 - no restrictions
Well-Documented: Structure specification available
Contact Data: Phone, email, website for each institution
Geographic Data: GPS coordinates already provided

Notable Features

🌟 GPS Coordinates: All institutions have lat/lon data - no geocoding needed!
🌟 Collection Statistics: Book counts, periodical counts, collection year
🌟 Opening Hours: Detailed schedule by day of week
🌟 Library Systems: Information about ILS/catalog software used
🌟 Hierarchical Structure: Departments and branches properly linked

Limitations

⚠️ Custom MARC Format: Not standard MARC21 bibliographic (custom tags: SGL, NAZ, VAR, etc.)
⚠️ Sigla vs ISIL: Uses "siglas" (ABA000, ABA001) not standard ISIL format (CZ-XXXXX)
⚠️ Czech Documentation: Most documentation in Czech language
⚠️ ISIL Mapping: Need to investigate relationship between siglas and official ISIL codes


🔑 Key Findings

ISIL Code Format Issue

The database uses "siglas" (library codes) like:

  • ABA000 (National Library)
  • ABA001 (National Library - Services Division)
  • BOE301 (Public libraries)
  • etc.

These are NOT standard ISO 15511 ISIL codes (format: CZ-XXXXX).

Action Required:

  • Investigate if there's a mapping between siglas and official ISIL codes
  • Check if CZ-* codes exist in parallel
  • Contact NK ČR for clarification if needed

Institution Type Mapping

Czech types need to be mapped to GLAMORCUBESFIXPHDNT taxonomy:

  • NK (Národní knihovna) → LIBRARY (National)
  • VK (Vysokoškolská knihovna) → LIBRARY (Academic)
  • MK (Městská knihovna) → LIBRARY (Public)
  • KI (Knihovna kulturní instituce) → LIBRARY (Special)
  • Archives with siglas → ARCHIVE
  • Museum libraries → MUSEUM

🛠️ Next Steps for Integration

Immediate (Ready to Execute)

  1. Download complete - 8,145 records harvested
  2. Parse MARC21 XML to extract all fields
  3. Map institution types to GLAMORCUBESFIXPHDNT taxonomy
  4. Use GPS coordinates for location data (no geocoding needed!)
  5. Generate LinkML-compliant YAML instances

Investigation Required

  1. Clarify sigla vs ISIL code relationship
  2. Check if CZ-* format codes exist in parallel
  3. Cross-reference with official ISO 15511 ISIL registry
  4. Contact NK ČR if mapping documentation unavailable

Data Integration

  1. Create Czech-specific parser for MARC21 format
  2. Map Czech institution types to GLAM taxonomy
  3. Handle IČO (Czech company registration numbers)
  4. Extract collection metadata for heritage custodian records
  5. Link departments/branches hierarchically
