Raw Blame History

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:

# 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:

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

Record Example (simplified):

- 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.

  4. src/glam_extractor/parsers/argentina_conabip.py - Fixed typo

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.
