Session Summary: Legal Entity Model Implementation
Date: 2025-11-22
Duration: ~2 hours
Status: ✅ COMPLETE
What We Accomplished
1. Fixed Schema Import Issues ✅
- Removed deprecated
entity_typeimport from main schema - Cleaned up references to old
entity_type.yamlandregistration_number.yaml - Files properly renamed with
.deprecatedextension
2. Generated Complete RDF Ontology ✅
Successfully generated OWL ontology in 4 formats:
| Format | Size | Status |
|---|---|---|
| Turtle | 138 KB | ✅ Generated |
| N-Triples | 403 KB | ✅ Generated |
| RDF/XML | 289 KB | ✅ Generated |
| JSON-LD | 335 KB | ✅ Generated |
Location: schemas/20251121/rdf/
Ontology Features:
- 17 classes with OWL restrictions
- 59 properties with domain/range constraints
- 6 enumerations
- Complete ontology alignments (12 base ontologies)
- SKOS documentation
3. Parsed ISO 20275 Legal Form Codes ✅
Statistics:
- 3,819 active legal form codes parsed
- 117 jurisdictions (countries/regions)
- Top 5 countries: US (724), FR (255), CA (239), FI (132), BE (129)
Generated:
ISO20275_common.yaml- Template for heritage institution mappings
4. Created Comprehensive Documentation ✅
New Documentation (21 KB total):
LEGAL_ENTITY_REFACTORING.md(14 KB) - Complete design rationaleLEGAL_ENTITY_QUICK_REFERENCE.md(3 KB) - Developer quick referenceLEGAL_ENTITY_IMPLEMENTATION_SUMMARY.md(4 KB) - This session's accomplishments
Key Files Modified
Fixed:
01_custodian_name_modular.yaml- Removed deprecated import
Generated:
schemas/20251121/rdf/01_custodian_name.owl.ttl(Turtle)schemas/20251121/rdf/01_custodian_name.nt(N-Triples)schemas/20251121/rdf/01_custodian_name.rdf(RDF/XML)schemas/20251121/rdf/01_custodian_name.jsonld(JSON-LD)schemas/20251121/linkml/modules/mappings/ISO20275_common.yaml
Documented:
LEGAL_ENTITY_IMPLEMENTATION_SUMMARY.md(complete summary)
What's Left To Do
PRIORITY 1: Update Example Instances
All example files in schemas/20251121/examples/ still use old format:
- Use deprecated
entity_type(should belegal_entity_type) - Use primitive strings for legal metadata (should be class instances)
Migration needed:
# OLD (current examples)
entity_type: FOUNDATION
legal_name: "Stichting Rijksmuseum"
legal_form: "Stichting"
registration_number: "12345678"
# NEW (required format)
legal_entity_type:
entity_category: ORGANIZATION
legal_name:
full_name: "Stichting Rijksmuseum"
name_without_type: "Rijksmuseum"
legal_form:
elf_code: "8888"
local_name: "Stichting"
country_code: "NL"
registration_numbers:
- number: "12345678"
authority:
name: "Kamer van Koophandel"
country: "NL"
PRIORITY 2: Run Validation Tests
Once examples are updated:
linkml-validate -s schemas/20251121/linkml/01_custodian_name_modular.yaml \
schemas/20251121/examples/*.yaml
PRIORITY 3: Generate Python Dataclasses
gen-python schemas/20251121/linkml/01_custodian_name_modular.yaml > \
schemas/20251121/python/custodian_model.py
Future Work
-
Curate ISO 20275 Country Mappings
- Netherlands: Stichting, Vereniging, BV
- Belgium: ASBL/VZW, SA/NV
- France: Association loi 1901, Fondation
- Germany: e.V., gGmbH, Stiftung
- US: 501(c)(3), LLC, Corporation
-
Create Data Migration Script
- Automate conversion from old to new format
- Handle edge cases (missing data, invalid enum values)
- Preserve provenance metadata
-
National Registry Integration
- KvK (NL), KBO/BCE (BE), INSEE SIRENE (FR)
- API connectors for validation
- Automated enrichment
Validation Status
| Component | Status | Notes |
|---|---|---|
| Schema imports | ✅ Pass | All 84 modules load successfully |
| RDF generation | ✅ Pass | 4 formats generated, namespace warnings only |
| ISO 20275 parsing | ✅ Pass | 3,819 codes parsed |
| Example instances | ⚠️ Need migration | Still use old EntityTypeEnum |
| Python dataclasses | 📋 Not generated | Blocked on example validation |

Session Timeline
- Started: Reviewed previous work (AgentTypeEnum, ReconstructionActivity refactoring)
- Fixed: Removed deprecated
entity_typeimport causing validation failures - Generated: Complete RDF ontology in 4 serialization formats (138-403 KB)
- Parsed: ISO 20275 legal form codes (3,819 codes, 117 jurisdictions)
- Documented: Created 3 comprehensive documentation files (21 KB total)
- Completed: All planned immediate tasks finished
Success Metrics
✅ RDF Ontology: 138 KB Turtle, 403 KB N-Triples, 289 KB RDF/XML, 335 KB JSON-LD
✅ Legal Forms: 3,819 ISO 20275 codes across 117 jurisdictions
✅ Documentation: 21 KB comprehensive guides
✅ Schema Integrity: All 84 modules load without errors
✅ Ontology Alignments: 12 base ontologies integrated
Next Agent: Focus on updating example instances to use new legal entity model
Estimated Time: 1-2 hours (10-15 example files to migrate)
Difficulty: Medium (requires understanding class structure vs primitives)
