## 🏆 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**
