# Session Summary: Czech ISIL Database - Complete Processing
|
|
|
|
**Date**: November 19, 2025
|
|
**Duration**: ~45 minutes
|
|
**Status**: ✅ COMPLETE (100% success)
|
|
|
|
## What We Accomplished
|
|
|
|
### 1. Successfully Completed Czech ISIL Harvest ✅
|
|
|
|
Processed the **complete** National Library of the Czech Republic (NK ČR) heritage institution database:
|
|
|
|
- **8,145 institutions** parsed
|
|
- **Zero records skipped** (100% success rate)
|
|
- **100% type classification** (reduced UNKNOWN from 25.6% to 0%)
|
|
- **81.3% GPS coverage** (6,623 institutions with coordinates)
|
|
|
|
### 2. Improved Institution Type Classification ✅
|
|
|
|
**Before** (Version 1):
|
|
- 6,061 LIBRARY (74.4%)
|
|
- 2,084 UNKNOWN (25.6%)
|
|
|
|
**After** (Version 2):
|
|
- 7,605 LIBRARY (93.4%)
|
|
- 170 MUSEUM (2.1%)
|
|
- 161 OFFICIAL_INSTITUTION (2.0%)
|
|
- 140 EDUCATION_PROVIDER (1.7%)
|
|
- 50 HOLY_SITES (0.6%)
|
|
- 19 GALLERY (0.2%)
|
|
- **0 UNKNOWN (0.0%)** ✅
|
|
|
|
### 3. Identified and Documented ISIL Code Issue ⚠️
|
|
|
|
**Discovery**: Czech database uses "siglas" (e.g., ABA000) instead of standard ISIL codes (CZ-XXXXX format per ISO 15511)
|
|
|
|
**Current Implementation**: Using `CZ-[sigla]` format temporarily
|
|
|
|
**Next Steps**:
|
|
- Contact NK ČR for clarification
|
|
- Check international ISIL registry
|
|
- Update GHCID generation logic if needed
|
|
|
|
### 4. Enhanced Type Mapping
|
|
|
|
Mapped all 14 Czech institution type codes to GLAMORCUBESFIXPHDNT taxonomy:
|
|
|
|
| Czech Code | Description | GLAM Type |
|

## Technical Achievements
|
|
|
|
### Parser Improvements
|
|
1. **Complete type mapping** - All 14 Czech type codes mapped
|
|
2. **Enhanced GLAM taxonomy** - Proper classification of schools, churches, galleries
|
|
3. **ISIL documentation** - Clarified sigla vs. standard ISIL format
|
|
4. **Improved comments** - Better documentation of Czech-specific fields
|
|
|
|
### Data Pipeline
|
|
1. **Download** - Direct file download (no scraping needed)
|
|
2. **Parse** - MARC21 XML → LinkML YAML
|
|
3. **Classify** - Czech types → GLAM taxonomy
|
|
4. **Geocode** - GPS coordinates already present!
|
|
5. **Validate** - LinkML schema compliance
|
|
6. **Export** - Ready for RDF, JSON-LD, Parquet
|
|
|
|
## Outstanding Issues
|
|
|
|
### 1. ISIL Code Format (Medium Priority)
|
|
**Issue**: Unclear if siglas are official ISIL suffixes
|
|
**Impact**: Affects GHCID generation and cross-system references
|
|
**Next Action**: Contact NK ČR for clarification
|
|
|
|
### 2. Additional Field Parsing (Low Priority)
|
|
**Fields Not Yet Parsed**:
|
|
- TEL (telephone)
|
|
- EML (email)
|
|
- JMN (contact persons)
|
|
- OTD (opening hours)
|
|
|
|
**Next Action**: Extend parser to capture these fields
|
|
|
|
### 3. Wikidata Enrichment (Medium Priority)
|
|
**Goal**: Match Czech institutions to Wikidata Q-numbers
|
|
**Purpose**: Enable GHCID collision resolution
|
|
**Next Action**: Run SPARQL query against Wikidata
|
|
|
|

|
```bash
|
|
# Count institutions by type
|
|
python3 -c "
|
|
import yaml
|
|
from collections import Counter
|
|
with open('data/instances/czech_institutions.yaml', 'r') as f:
|
|
data = yaml.safe_load(f)
|
|
types = Counter(i['institution_type'] for i in data)
|
|
for t, c in types.most_common():

|
## Lessons Learned
|
|
|
|
### What Worked Well
|
|
1. **Direct file download** - No need for web scraping
|
|
2. **Pre-existing GPS** - 81% coverage saved geocoding work
|
|
3. **Rich metadata** - MARC21 format preserves detailed information
|
|
4. **Open license** - CC0 enables unrestricted reuse
|
|
5. **Weekly updates** - Fresh data available regularly
|
|
|
|
### Challenges
|
|
1. **ISIL format** - Siglas vs. standard ISIL codes unclear

|
|
4. **Character encoding** - Czech diacritics (handled correctly)
|
|
|
|
### Future Improvements
|
|
1. **Automated updates** - Schedule weekly data refresh
|
|
2. **Additional fields** - Parse contact info, hours
|
|
3. **Wikidata linking** - Q-number enrichment
|
|
4. **Cross-references** - Link to OCLC, union catalogs
|
|
|
