tooi:Informatieobject,prov:Entity,dcat:Resource - Close:
rico:RecordSet,crm:E78_Curated_Holding,bf:Collection
2. Created Bidirectional Relationship Slots ✅
Forward Relationship: responsible_legal_entity
File: schemas/20251121/linkml/modules/slots/responsible_legal_entity.yaml
- Property:
tooi:verantwoordelijke(TOOI: "responsible organization") - Range:
CustodianLegalStatus - Inverse:
collections_under_responsibility - Required:
true
Reverse Relationship: collections_under_responsibility
File: schemas/20251121/linkml/modules/slots/collections_under_responsibility.yaml
- Property:
tooi:heeft_informatieobject(custom: "has information object") - Range:
LegalResponsibilityCollection - Inverse:
responsible_legal_entity - Multivalued:
true - Required:
false
3. Created Supporting Temporal Slots ✅
legal_responsibility_basis
File: schemas/20251121/linkml/modules/slots/legal_responsibility_basis.yaml
- Property:
dcterms:conformsTo - Purpose: Documents statutory/regulatory/contractual foundation for legal accountability
- Examples: "Archiefwet 1995", "Erfgoedwet + Foundation statute"
legal_responsibility_start_date
File: schemas/20251121/linkml/modules/slots/legal_responsibility_start_date.yaml
- Property:
prov:generatedAtTime - Purpose: When legal responsibility began (may differ from collection creation date)
legal_responsibility_end_date
File: schemas/20251121/linkml/modules/slots/legal_responsibility_end_date.yaml
- Property:
prov:invalidatedAtTime - Purpose: When legal responsibility ended (custody transfer, deaccession, dissolution)
4. Updated Schema Structure ✅
Main Schema (01_custodian_name_modular.yaml)
- ✅ Added import:
modules/classes/LegalResponsibilityCollection - ✅ Added 5 slot imports:
collections_under_responsibilityresponsible_legal_entitylegal_responsibility_basislegal_responsibility_start_datelegal_responsibility_end_date
CustodianLegalStatus Class
- ✅ Added slot:
collections_under_responsibility - ✅ Creates reverse link from legal entity to collections
Fixed CustodianCollection.yaml
- ✅ Resolved duplicate
slot_usagekeys (lines 46 and 80) - ✅ Merged validation constraints with slot definitions
- ✅ Removed duplicate entries for:
collection_name(line 176)managing_unit(line 102)valid_from(line 200)valid_to(line 208)
5. Updated UML Diagrams ✅
File: schemas/20251121/uml/mermaid/CustodianLegalStatus.md
Added relationship:
CustodianLegalStatus --> "*" LegalResponsibilityCollection : collections_under_responsibility

🔗 Key Distinctions
LegalResponsibilityCollection vs. CustodianCollection
| Aspect | LegalResponsibilityCollection | CustodianCollection (Parent) |
|---|---|---|
| Legal Accountability | Formal legal responsibility documented | May or may not have legal accountability |
| Use Case | Government archives, mandated collections | All heritage collections (including private) |
| Required Properties | responsible_legal_entity, legal_responsibility_basis |
None beyond basic collection metadata |
| Ontology Mapping | tooi:Informatieobject |
crm:E78_Curated_Holding |
| Example | National archive under Archiefwet 1995 | Private collection donated to museum |
responsible_legal_entity vs. managing_unit
| Property | Level | Purpose | Range |
|---|---|---|---|
| responsible_legal_entity | Top-level | Legal accountability | CustodianLegalStatus |
| managing_unit | Operational | Day-to-day management | OrganizationalStructure |
Example:
LegalResponsibilityCollection:
# TOP LEVEL: Who is legally responsible?
responsible_legal_entity: ".../legal/rijksmuseum-foundation" # Stichting Rijksmuseum
# OPERATIONAL: Which department manages it?
managing_unit: ".../org-unit/rm-paintings-dept" # Paintings Department

🎓 Implementation Insights
Why This Pattern Matters
- Legal Compliance: Heritage institutions operate under statutory mandates (Archiefwet, Erfgoedwet, UNESCO conventions)
- Custody Accountability: Clear documentation of which legal entity is responsible for collection preservation
- Organizational Change Tracking: Mergers, splits, and transfers don't change collection physical identity but DO change legal responsibility
- TOOI Alignment: Dutch government heritage data integrates with national interoperability standards
Temporal Dimension is Critical
Collections have THREE temporal dimensions:
- Material Existence:
valid_from/valid_to(when collection physically existed) - Legal Responsibility:
legal_responsibility_start_date/legal_responsibility_end_date(when legal accountability applied) - Material Coverage:
temporal_coverage(time period of materials in collection)
Example:
# 17th-century manuscripts (materials: 1600-1699)
temporal_coverage: "1600-01-01/1699-12-31"
# Accessioned as collection in 1910
valid_from: "1910-01-01"
# Legal responsibility transferred to NHA in 2001
legal_responsibility_start_date: "2001-01-01"
Bidirectional Relationships Enable Rich Queries
Query 1: "What collections is this organization responsible for?"
CustodianLegalStatus → collections_under_responsibility → LegalResponsibilityCollection
Query 2: "Who is legally responsible for this collection?"
LegalResponsibilityCollection → responsible_legal_entity → CustodianLegalStatus
Query 3: "What happened to collections when this entity dissolved?"
CustodianLegalStatus (dissolution_date set)
→ collections_under_responsibility (filter: legal_responsibility_end_date)
→ custody_history (track transfers)
🚀 Next Steps
Phase 1: Validation (Recommended)
- Create
LinkMLvalidation tests forLegalResponsibilityCollection - Test bidirectional relationship integrity
- Validate temporal consistency (start_date < end_date, etc.)
- Create SHACL shapes for legal responsibility constraints
Phase 2: Regeneration (Required)
- Regenerate RDF/OWL schema with full timestamps:
TIMESTAMP=$(date +%Y%m%d_%H%M%S) gen-owl -f ttl schemas/20251121/linkml/01_custodian_name_modular.yaml \ > schemas/20251121/rdf/01_custodian_name_${TIMESTAMP}.owl.ttl - Generate all 8 RDF formats (nt, jsonld, rdf, n3, trig, trix, hext, nq)
- Update UML diagrams for
LegalResponsibilityCollectionclass
Phase 3: Documentation (Optional)
- Add example instances to
data/instances/ - Create data entry guide for legal responsibility collections
- Document custody transfer workflow
- Add SPARQL query cookbook for legal responsibility patterns
