## 🏆 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
