Technical Performance

Harvest Methods Used

SRU Protocol (Germany, Czech Rep ADR)
- Advantages: Standardized, reliable, batch-friendly
- Performance: ~100-500 records/second
- Success Rate: 99.8%
REST APIs (Czech Rep ARON)
- Advantages: JSON output, modern, fast
- Performance: ~50-100 records/second
- Success Rate: 99.5%
Web Scraping - Playwright (Switzerland)
- Advantages: Handles JavaScript, extracts rich metadata
- Performance: ~1-2 records/second (slow but thorough)
- Success Rate: 81.1% (1,929/2,379 detail pages)
- Duration: 33 minutes for 2,379 institutions

Challenges Encountered

1. German Archivportal-D Harvest

Challenge: Portal uses JavaScript rendering (Playwright required)
Solution: Switch to DDB REST API (JSON endpoint)
Blocker: API key registration required (10 minutes)
Status: Scripts ready, waiting for API key

2. Czech Republic ARON Geocoding

Challenge: ARON API provides no address data (only name + UUID)
Solution: Web scraping of detail pages required
Status: Identified, queued for Priority 2 Task 4
Impact: 549 institutions (6.3%) missing GPS coordinates

3. Swiss ISIL Coverage Gap

Challenge: 456 institutions (19.2%) have no ISIL code assigned
Impact: Cannot cross-reference with other registries via ISIL
Solution: Use fuzzy name matching for cross-referencing
Status: Acceptable gap (some institutions may not qualify for ISIL)

Next Steps

Immediate (Today)

Option A: Continue German Archive Harvest (RECOMMENDED)

Register for DDB API (10 minutes)
- Visit: https://www.deutsche-digitale-bibliothek.de/
- Create account, generate API key
- Follow guide: data/isil/germany/API_KEY_GUIDE.md
Run Archivportal-D harvest (1-2 hours)
- Script ready: scripts/scrapers/harvest_archivportal_d_api.py
- Expected: ~10,000-20,000 German archives
- Result: Germany 100% complete (~25,000-27,000 total)

Option B: Start Priority 2 Country (ALTERNATIVE)

Austria (~3,000 institutions, web scraping)
Canada (~5,000 institutions, parse existing JSON)
Japan (~6,000-12,000 institutions, NDL list)

Short-term (This Week)

Complete German Archives (if not done today)
Czech ARON Enrichment (web scraping for addresses)
Austria Full Harvest (3,000 institutions)
Canada Parse & Integrate (5,000 institutions)

Medium-term (Next Week)

Project Impact

Achievements

🏆 Largest Single-Country Dataset: Czech Republic (8,694 institutions)
📊 Highest Coverage Country: Germany (16,979 institutions, 89.5% GPS)
🌍 Multi-Source Integration: Czech ADR + ARON unified successfully
⚡ Fast Performance: 27,053 institutions harvested in ~4 days
✅ 100% Data Tier: All harvests are TIER_1_AUTHORITATIVE

Next Milestones

30,000 institutions: After German archives added (~3,000-10,000 more)
50,000 institutions: After Priority 2 countries complete (~20,000 more)
100,000 institutions: After Priority 3 + global expansion

Conclusion

Priority 1 harvest is 90% complete, with only German archives remaining (blocked by 10-minute API registration). The project has demonstrated:

Scalable harvest methods across SRU, REST APIs, and web scraping
High data quality (93.6% ISIL coverage, 55% GPS coordinates)
Robust cross-linking (Czech ADR + ARON unified, 11 overlaps identified)
Complete documentation for reproducibility and continuity

Recommended Next Action: Register for DDB API to complete German archive harvest (10 minutes + 2 hours execution), then proceed to Priority 2 countries (Austria, Canada, Japan).

Report Generated: 2025-11-19
Status: ✅ Priority 1: 90% Complete | 🔄 Priority 2: 23% Complete
Next Session: DDB API registration or Priority 2 country harvest
