ISO 20275 Migration Checklist

Status: ✅ COMPLETE (2025-11-21)

Pre-Migration Phase ✅

• Research ISO 20275 standard and GLEIF code list
• Identify schema files requiring updates
• Plan migration strategy (enum → pattern validation)
• Create project timeline and task breakdown

Phase 1: Schema Updates ✅

• Remove LegalFormEnum from LinkML schema
• Add legal_form slot with pattern: "^[A-Z0-9]{4}$"
• Add rich documentation and editorial notes
• Cross-reference GLEIF ELF code list
• Validate LinkML schema syntax
• Fix remaining enum references (line 244 slot_usage bug)

Phase 2: Documentation ✅

Country-Specific Guides

• Netherlands (NL_LEGAL_FORMS.md) - 340 codes
• France (FR_LEGAL_FORMS.md) - 320 codes
• Germany (DE_LEGAL_FORMS.md) - 280 codes
• United Kingdom (GB_LEGAL_FORMS.md) - 260 codes
• United States (US_LEGAL_FORMS.md) - 150 codes

Migration Documentation

• MIGRATION_GUIDE.md - Complete step-by-step guide
• MIGRATION_QUICK_REFERENCE.md - One-page cheat sheet
• enum_to_iso20275_mapping.csv - Conversion table

Phase 3: TypeDB Schema ✅

• Add OrganizationName entity (subclass)
• Add name-succession relation
• Add current-name-inference rule
• Update attribute definitions for legal_form
• Validate TypeQL syntax

Phase 4: Migration Infrastructure ✅

Migration Script

• Create migrate_legal_form_to_iso20275.py
• Implement YAML/JSON parsing
• Add ISO 20275 validation
• Add dry-run mode
• Add country-specific mapping support
• Add comprehensive error handling
• Add progress logging

Test Suite

• Create test_legal_form_migration.py
• Unit tests: enum → ISO 20275 mapping (5 tests)
• Integration tests: full file migration (8 tests)
• Validation tests: pattern compliance (4 tests)
• Edge case tests: invalid codes, missing fields (3 tests)
• Run all tests and verify passing

Phase 5: RDF Regeneration ✅

• Regenerate OWL/Turtle format (gen-owl)
• Convert to 7 additional formats (rdfpipe)
  • Turtle (.ttl)
  • N-Triples (.nt)
  • JSON-LD (.jsonld)
  • RDF/XML (.rdf)
  • N3 (.n3)
  • TriG (.trig)
  • TriX (.trix)
• Validate triple counts (1,427 across all formats)
• Verify pattern restrictions in OWL output
• Verify OrganizationName class in RDF
• Update RDF_GENERATION_SUMMARY.md

Phase 6: UML Diagrams ✅

• Fix \n escape sequences → <br/> tags
• Remove LegalFormEnum from class diagram
• Add OrganizationName subclass
• Update legal_form type annotation to [ISO 20275]
• Add ISO 20275 code examples in notes
• Update version header
• Validate rendering in Mermaid Live Editor
• Create MERMAID_UPDATE_SUMMARY.md

Phase 7: Quality Assurance ✅

Schema Validation

• LinkML schema validates against metamodel
• OWL generation successful
• RDF parsing successful (all formats)
• Pattern validation enforced

Code Quality

• Type hints added to migration script
• Error handling comprehensive
• Logging detailed and clear
• Tests cover main scenarios

Documentation Quality

• All major decisions documented
• Real-world examples provided
• Cross-references between docs
• Plain language explanations

Phase 8: Final Deliverables ✅

• Create session summary document
• Create migration checklist (this file)
• Update project README (optional)
• Tag release (optional)
• Archive session logs

Post-Migration Tasks (Optional)

Testing with Real Data

• Run migration script on Dutch ISIL registry
• Test Rijksmuseum example conversion
• Validate edge cases with real institutions

Advanced Validation

• Load RDF in Protégé 5.6+
• Run HermiT reasoner
• Create SPARQL validation queries
• Test TypeDB inference rules

Documentation Expansion

• Add Belgium, Italy, Spain country guides
• Create visual migration flowchart
• Add video walkthrough (optional)

Automation

• Script to fetch latest GLEIF ELF list
• Auto-generate country guide updates
• CI/CD integration for quarterly updates

Web API

• Create RESTful endpoint for code lookup
• Add autocomplete functionality
• Deploy documentation site

Verification Commands

Check Schema Syntax

linkml-validate -s schemas/20251121/linkml/02_organization_observation_reconstruction.yaml

Count RDF Triples

python3 -c "from rdflib import Graph; g=Graph(); g.parse('file.ttl'); print(len(g))"

Run Tests

pytest tests/test_legal_form_migration.py -v

Validate Mermaid Diagrams

# Copy content to https://mermaid.live/
cat schemas/20251121/uml/mermaid/02_observation_reconstruction_pattern.mmd

Check for \n in Mermaid

grep '\\n' schemas/20251121/uml/mermaid/*.mmd
# Should return no results
