Session Summary: Danish GLAM Data Harvest - COMPLETE

Date: 2025-11-19
Status: ✅ COMPLETE - Denmark Priority 1 country fully harvested
Total Institutions: 1,162 (568 libraries + 594 archives)

What We Accomplished

1. Danish Libraries Data - COMPLETE ✅

Downloaded 4 CSV files from VIP-basen (official library database)
568 unique library institutions, 1,326 service locations
✅ All have ISIL codes (DK-XXXXXX format)

2. Danish Archives Data - COMPLETE ✅

Scraped 594 archive institutions from Arkiv.dk portal
565 municipal archives + 29 special collections (including Rigsarkivet)
❌ NO ISIL codes - Danish archives don't use international ISIL codes

3. Critical Discovery

Danish ISIL codes (DK-*) are ONLY for libraries, NOT archives

This is different from many countries. Danish archives will require GHCID identifiers instead.

Files Created

Data:

/data/isil/denmark/danish_archives_arkivdk.csv (594 records)
/data/isil/denmark/danish_archives_arkivdk.json (with metadata)
4 library CSV files (previously downloaded)

Scripts:

/scripts/scrapers/scrape_danish_archives_playwright.py (v2.0.0)

Documentation:

/data/isil/denmark/README.md (comprehensive update)
SESSION_SUMMARY_20251119_DENMARK_ISIL_COMPLETE.md (this file)

Technical Breakthrough

Problem: Arkiv.dk uses JavaScript-rendered collapsed panels
Initial approach: Click each of 100 panels (SLOW - 2+ minutes, timeout issues)
Solution: JavaScript evaluation to extract all data at once
Result: ✅ 5 seconds (24x speedup!)
