Preserves source data 2. **adr.xml** (27 MB) - Decompressed MARC21 XML - Ready for parsing 3. **README.md** (3.3 KB) - Quick reference guide - Summary statistics - Contact information 4. **czech_isil_analysis.md** (4.3 KB) - Detailed technical analysis - Field structure documentation - Data quality assessment - Next steps for integration --- ## 🏆 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** --- ## 📋 Sample Records ### Record 1: National Library of Czech Republic ```yaml sigla: ABA000 name: Národní knihovna České republiky english_name: National Library of the Czech Republic type: NK - národní knihovna founded: 1602 address: Mariánské náměstí 190/5, 110 00 Praha 1 gps: 50°5'11.12"N, 14°24'56.61"E phone: +420 221 663 111 website: https://www.nkp.cz collections: books: 6,919,075 volumes periodicals: 10,449 titles year: 2015 system: ALEPH ``` ### Record 5: French Institute Library ```yaml sigla: ABA005 name: Francouzský institut - Mediatéka english_name: Institut français de Prague type: KI - knihovna kulturní instituce address: Štěpánská 35, 110 26 Praha 1 gps: 50°4'43.84"N, 14°25'30.42"E website: https://www.ifp.cz/cz/mediateka/ catalog: https://prague.bibenligne.fr/ collections: books: 60,000 volumes periodicals: 25 titles year: 2023 ``` --- ## 🛠️ Next Steps for Integration ### Immediate (Ready to Execute) 1. ✅ Download complete -
