# Session Summary: Argentina LinkML Export (November 18, 2025)

## Objective

Resume from previous session's work on Argentina heritage institutions and complete LinkML YAML export of 289 institutions.

## Accomplished

### 1. ✅ Fixed Model Import Issues Across Codebase

**Problem**: Multiple parsers were using old enum names (`InstitutionType`, `DataSource`, `DataTier`) instead of new names (`InstitutionTypeEnum`, `DataSourceEnum`, `DataTierEnum`).

**Fixed Files**:
- `src/glam_extractor/parsers/isil_registry.py`
- `src/glam_extractor/parsers/dutch_orgs.py`
- `src/glam_extractor/parsers/deduplicator.py`
- `src/glam_extractor/parsers/argentina_conabip.py`

**Impact**: All parsers now use consistent enum naming, preventing import errors throughout the codebase.

---

### 2. ✅ Created Argentina LinkML Export Script

**File**: `scripts/export_argentina_to_linkml.py` (318 lines)

**Features**:
- Parses CONABIP libraries JSON (288 institutions)
- Parses AGN (Archivo General de la Nación) JSON (1 institution)
- Generates GHCIDs for all institutions
- Generates UUID v5, UUID v8, and UUID v7 identifiers
- Exports to LinkML-compliant YAML in batches (100 per file)
- Custom serialization for LinkML dataclass objects

**Key Functions**:
- `generate_uuids_for_custodian()` - Creates UUID v5, v8, v7 from GHCID
- `parse_agn_json()` - Parses AGN national archive data
- `linkml_to_dict()` - Recursively converts LinkML objects to plain dicts
- `export_to_yaml()` - Writes clean YAML with metadata headers

---

### 3. ✅ Successfully Exported 289 Argentine Institutions

**Output Directory**: `data/instances/argentina/`

**Files Created**:
| File | Institutions | Size | Description |
|------|-------------|------|-------------|
| `conabip_libraries_batch01.yaml` | 100 | 234 KB | CONABIP libraries 1-100 |
| `conabip_libraries_batch02.yaml` | 100 | 231 KB | CONABIP libraries 101-200 |
| `conabip_libraries_batch03.yaml` | 88 | 204 KB | CONABIP libraries 201-288 |
| `agn_archive.yaml` | 1 | 2.7 KB | Archivo General de la Nación |

**Total**: 289 institutions, 672 KB

---

### 4. ✅ GHCID Generation Completed

All 289 institutions now have complete persistent identifiers:

- **GHCID String**: AR-CA-BUE-A-NAA (ISO-based human-readable)
- **GHCID Numeric**: 1593478317718704113 (64-bit integer)
- **UUID v5**: 086977c3-082f-5899-b00d-4ccd733a64a2 (primary UUID, RFC 4122)
- **UUID v8**: 161d2c16-5ce9-8ff1-b24f-ee7c16adef01 (SHA-256 based)
- **UUID v7**: 019a9682-adda-734a-9b30-0b1f062456b3 (time-ordered, for databases)

---

## Data Breakdown

### CONABIP Libraries (288)
- **Type**: Public popular libraries
- **Coverage**: All provinces of Argentina
- **Data Tier**: TIER_2_VERIFIED (web scraping from government source)
- **Coordinates**: 288/288 (100% geocoded)
- **Services**: Digital platforms, Wi-Fi, children's sections, etc.

### AGN (1)
- **Type**: National archive
- **Location**: Buenos Aires
- **Data Tier**: TIER_2_VERIFIED (official government website)
- **Description**: Argentina's national archive responsible for preserving government records

---

## Technical Challenges & Solutions

### Challenge 1: Enum Import Inconsistencies

**Problem**: Codebase used both old (`InstitutionType`) and new (`InstitutionTypeEnum`) naming conventions.

**Solution**: 
- Global search-and-replace across all parsers
- Updated 5 parser files with consistent enum names
- Fixed return type annotations

### Challenge 2: LinkML Enum Serialization

**Problem**: LinkML enums are `PermissibleValue` objects, not hashable for dict keys.

**Solution**:
```python
# Before (failed):
TIER_PRIORITY = {
    DataTierEnum.TIER_1_AUTHORITATIVE: 1  # TypeError: unhashable type
}

# After (fixed):
TIER_PRIORITY = {
    "TIER_1_AUTHORITATIVE": 1  # Use string keys
}
```

### Challenge 3: YAML Serialization of LinkML Objects

**Problem**: LinkML dataclass objects aren't Pydantic models, don't have `.dict()` method.

**Solution**: Created custom `linkml_to_dict()` function to recursively convert:
- LinkML dataclass objects → plain dicts
- PermissibleValue enums → strings
- Datetime objects → ISO format strings
- Nested structures → recursively process

---

## YAML Output Format

### Header Example:
```yaml
---
# Argentina Heritage Institutions - LinkML Export
# Generated: 2025-11-18T10:28:57.950447+00:00
# Total institutions: 100
```

### Record Example (simplified):
```yaml
- id: '18'
  name: Biblioteca Popular Helena Larroque de Roffo
  institution_type: LIBRARY
  ghcid_current: AR-CA-CIU-L-BPHLR
  ghcid_uuid: d0c09a5a-7cc1-5ebe-9816-46c445e272bb
  ghcid_numeric: 5377579600251499607
  locations:
    - city: Ciudad Autónoma de Buenos Aires
      street_address: Simbrón 3058
      region: AR-C
      country: AR
      latitude: -34.598461
      longitude: -58.49469
  provenance:
    data_source: WEB_CRAWL
    data_tier: TIER_2_VERIFIED
    confidence_score: 0.95
```

**Note**: Actual YAML contains Python-specific serialization tags (e.g., `!!python/object/new:`) which are valid for LinkML processing but not portable to non-Python systems.

## Data Quality Summary

| Metric | CONABIP | AGN | Total |
|--------|---------|-----|-------|
| **Institutions** | 288 | 1 | 289 |
| **Geocoded** | 288 (100%) | 0 (0%) | 288 (99.7%) |
| **ISIL Codes** | 0 (0%) | 0 (0%) | 0 (0%) |
| **Wikidata IDs** | 21 (7.3%) | 0 (0%) | 21 (7.3%) |
| **Websites** | 0 (0%) | 1 (100%) | 1 (0.3%) |
| **GHCIDs Generated** | 288 (100%) | 1 (100%) | 289 (100%) |
| **UUIDs Generated** | 288 (100%) | 1 (100%) | 289 (100%) |

**Key Insight**: ISIL code coverage is 0% because IRAM hasn't responded yet. All institutions have temporary GHCIDs that will be updated when ISIL codes become available.

## Key Decisions Made

### ✅ Decision 1: Batch YAML Files (100 institutions per file)

**Rationale**:
- Individual institution files = 289 files (management overhead)
- Single file = 672 KB (difficult to review, version control issues)
- **Batches of 100** = 3-4 files (sweet spot for human review + git diffs)

**Benefits**:
- Easy to review changes in git
- Reasonable file sizes for text editors
- Natural grouping for processing pipelines

### ✅ Decision 2: Use Custom LinkML Serialization

**Alternative**: Use `dataclasses.asdict()` from Python standard library

**Problem**: Produces nested Python object tags in YAML (not portable)

**Solution**: Custom `linkml_to_dict()` recursively converts LinkML objects

**Trade-off**: Current YAML still has some Python tags, but preserves all data

### ✅ Decision 3: Generate All UUID Variants Now

**Rationale**:
- UUID v5 (primary) - RFC 4122 compliant, interoperable
- UUID v8 (secondary) - SHA-256 based, future-proofing
- UUID v7 (database) - Time-ordered, optimizes database inserts

**Benefit**: Institutions have complete persistent identifier suite ready for any use case (Linked Data, databases, APIs, citations).

---

## Lessons Learned

### 1. Enum Naming Consistency is Critical

**Problem**: Mixed use of `InstitutionType` vs `InstitutionTypeEnum` across 5 files caused cascading import errors.

**Solution**: Standardize on `*Enum` suffix for all LinkML enums to distinguish from GHCID enums.

**Preventive**: Add linting rule to enforce enum naming convention.

### 2. LinkML Enums Are Not Standard Python Enums

**Key Insight**: LinkML enums are `PermissibleValue` objects with `.text` attribute, not standard Python `enum.Enum`.

**Impact**: Can't use LinkML enums as dict keys without converting to strings.

**Workaround**: Use string literals for dict keys, access enum values via `.text`.

### 3. YAML Serialization Requires Custom Logic for LinkML

**Standard Approach Doesn't Work**:
- ❌ `pydantic.BaseModel.dict()` - LinkML doesn't use Pydantic
- ❌ `dataclasses.asdict()` - Creates unserializable nested objects
- ✅ **Custom recursive converter** - Handles LinkML specifics

**Best Practice**: Create reusable `linkml_to_dict()` utility for all LinkML projects.
