# Next Session Handoff

**Last Updated**: 2025-11-20  
**Current Focus**: Czech Republic heritage data - Wikidata enrichment complete

---

## 🇨🇿 Czech Republic - Latest Session (2025-11-20) ✅ COMPLETE

### What We Accomplished

#### 1. ARON Metadata Analysis
- **Discovered**: ARON API has NO contact metadata (addresses, websites, phone, email)
- **Script**: `scripts/analyze_aron_metadata_sample.py`
- **Result**: Sample of 20 institutions showed 0% contact data coverage
- **Decision**: Skipped API enrichment (no data to extract)

#### 2. Wikidata Enrichment ✅ COMPLETE
- **Matched**: 6,719 of 8,694 institutions (77.3% coverage)
- **Method**: SPARQL query (8,234 Wikidata results) + fuzzy matching (≥85% threshold)
- **Quality**: 96.6% high confidence matches (≥90% similarity)
- **Script**: `scripts/enrich_czech_wikidata.py`
- **Output**: `data/instances/czech_unified.yaml` (11 MB, enriched)

#### 3. Czech Dataset Now #1 Globally
- **Total**: 8,694 institutions
- **Wikidata Q-numbers**: 6,719 (77.3%) ← **BEST IN PROJECT**
- **GPS coordinates**: 6,623 (76.2%)
- **VIAF IDs**: 306 (3.5%)
- **Data tier**: 100% TIER_1_AUTHORITATIVE

### Priority 2 Task Status

| Task | Status | Notes |
|------|--------|-------|
| ✅ Task 1 | Complete | Cross-linked ADR + ARON (11 matches) |
| ✅ Task 2 | Complete | Fixed provenance metadata (API_SCRAPING) |
| ✅ Task 3 | Complete | Geocoded addresses (76.2% coverage) |
| ⏭️ Task 4 | Skipped | ARON API has no contact metadata |
| ✅ Task 5 | Complete | Wikidata enrichment (77.3% coverage) |
| 🔲 Task 6 | **NEXT** | ISIL code investigation |

### Files Created/Modified
- **`data/instances/czech_unified.yaml`** - 11 MB, 8,694 institutions (✅ enriched)
- **`data/instances/czech_unified_pre_wikidata.yaml`** - 9.1 MB (backup)
- **`CZECH_WIKIDATA_ENRICHMENT_COMPLETE.md`** - Comprehensive report
- **`scripts/enrich_czech_wikidata.py`** - Wikidata enrichment script
- **`scripts/analyze_aron_metadata_sample.py`** - ARON API sample analysis

### Next Steps for Czech Data

#### Option 1: ISIL Code Investigation (Task 6)
**Goal**: Increase ISIL coverage from 0.0% → 15%+

**Actions**:
1. Extract ISIL codes from existing Wikidata data (306 available)
2. Contact NK ČR (Czech National Library) for official ISIL registry
3. Query ISIL.org for Czech institutions (CZ-* codes)

#### Option 2: GHCID Generation
**Goal**: Create persistent identifiers for all 8,694 institutions

**Required**:
- Generate base GHCID from country + location + type
- Append Wikidata Q-numbers (already have 6,719)
- Create UUID v5, UUID v8, numeric identifiers
- Add GHCID history tracking

#### Option 3: RDF Export
**Goal**: Publish Czech data as Linked Open Data

**Format**: RDF/Turtle with CPOV, TOOI, Schema.org ontologies

## 🇦🇷 Argentina - Previous Session (2025-11-18)

### Status Summary

**Completed**:
- ✅ CONABIP Libraries (288 popular libraries scraped + Wikidata enriched)
- ✅ AGN (Archivo General de la Nación) national archive scraped
- ✅ Z39.50 investigation (determined unsuitable for ISIL extraction)
- ✅ Email drafts created (ready to contact IRAM and Biblioteca Nacional)

**Data Files Ready**:
- `data/isil/AR/conabip_libraries_wikidata_enriched.json` (288 libraries)
- `data/isil/AR/agn_argentina_archives.json` (1 archive)
- `data/isil/AR/EMAIL_DRAFTS_ISIL_REQUEST.md` (3 email templates)

### Next Steps for Argentina

#### 1. Send IRAM Email ⭐ TOP PRIORITY
**File**: `data/isil/AR/EMAIL_DRAFTS_ISIL_REQUEST.md` (Email #1)  
**To**: iram-iso@iram.org.ar  
**Subject**: Solicitud de acceso al registro nacional de códigos ISIL

**Expected outcome**: 60% chance of response with ISIL registry CSV/Excel (500-1,000 institutions)

#### 2. Complete CONABIP LinkML Export
Convert 288 CONABIP libraries to LinkML YAML while waiting for IRAM response.

## Quick Commands for Next Session

### Czech Republic
```bash
# Check current dataset
ls -lh data/instances/czech_unified.yaml

# Statistics
python3 -c "
import yaml
with open('data/instances/czech_unified.yaml', 'r') as f:
    data = yaml.safe_load(f)
wikidata = sum(1 for i in data if any(x.get('identifier_scheme') == 'Wikidata' for x in i.get('identifiers', [])))
print(f'Total: {len(data)}, Wikidata: {wikidata} ({wikidata/len(data)*100:.1f}%)')
"

# Next step: ISIL extraction
python3 scripts/extract_isil_from_wikidata.py  # Create this script
```

### Argentina
```bash
# Check data files
cat data/isil/AR/conabip_libraries_wikidata_enriched.json | jq 'length'
cat data/isil/AR/EMAIL_DRAFTS_ISIL_REQUEST.md
