Objectives Achieved

1. Created Two New Slots ✅

Slot 1: managing_unit (Collection → Unit)

File: schemas/20251121/linkml/modules/slots/managing_unit.yaml
Purpose: Links CustodianCollection to managing OrganizationalStructure
Property: org:unitOf (W3C ORG)
Cardinality: Single (one collection = one managing unit)

Slot 2: managed_collections (Unit → Collections)

File: schemas/20251121/linkml/modules/slots/managed_collections.yaml
Purpose: Links OrganizationalStructure to managed CustodianCollection(s)
Property: org:hasUnit (W3C ORG extension)
Cardinality: Multiple (one unit manages many collections)

2. Updated Two Classes ✅

Class 1: CustodianCollection

File: schemas/20251121/linkml/modules/classes/CustodianCollection.yaml
Changes:
- Added managing_unit slot

Key Design Decisions

1. Bidirectional Relationships

Decision: Implement both directions explicitly

Pattern:

CustodianCollection.managing_unit → OrganizationalStructure
OrganizationalStructure.managed_collections → CustodianCollection

Rationale: Enables queries from both perspectives, mirrors Phase 3 staff-unit pattern

2. One-to-Many Cardinality

Decision: One unit manages multiple collections (multivalued)

Rationale: Reflects institutional reality (Paintings Dept → Dutch, Flemish, Italian paintings)

3. Temporal Consistency Rules

Decision: Collection custody dates must align with managing unit validity

Rules:

Collection custody cannot start before unit founding
Collection custody must end when unit dissolves (or transfer to new unit)
Custody transfers during organizational changes must be documented

Example - Merger:

Before merger (2013-02-28): Collection → Old Unit
After merger (2013-03-01): Collection → New Merged Unit

4. Integration with PersonObservation

Decision: Enable three-way staff ↔ unit ↔ collections integration

Use Case: "Which curator manages the Medieval Manuscripts collection?"

Query Path:

Collection → managing_unit → OrganizationalStructure → staff_members → PersonObservation (role=CURATOR)

Technical Achievements

1. Ontology Alignment

W3C ORG Ontology:

org:unitOf - Collection managed by organizational unit
org:hasUnit - Organizational unit manages collection (extension)

CIDOC-CRM (implicit):

Collections as E78_Curated_Holding
Organizational units as E74_Group

PiCo (integration):

PersonObservation (staff) → OrganizationalStructure → CustodianCollection
Enables curator-collection queries

2. RDF/OWL Generation

Properties Generated:

custodian:managing_unit rdf:type owl:ObjectProperty ;
                        owl:inverseOf custodian:managed_collections ;
                        rdfs:domain custodian:CustodianCollection ;
                        rdfs:range custodian:OrganizationalStructure ;
                        rdfs:subPropertyOf org:unitOf .

custodian:managed_collections rdf:type owl:ObjectProperty ;
                              owl:inverseOf custodian:managing_unit ;
                              rdfs:domain custodian:OrganizationalStructure ;
                              rdfs:range custodian:CustodianCollection ;
                              rdfs:subPropertyOf org:hasUnit .

Features:

✅ Explicit inverse properties
✅ Domain/range constraints
✅ W3C ORG subproperties
✅ Full OWL 2 DL compliance

3. Mermaid ER Diagram

New Relationships:

CustodianCollection ||--o| OrganizationalStructure : "managing_unit"
OrganizationalStructure ||--o{ CustodianCollection : "managed_collections"

Cardinality Notation:

||--o| : One-to-zero-or-one (collection → unit)
||--o{ : One-to-many (unit → collections)

Validation Rules Documented

Temporal Consistency

Collection custody ⊆ Unit validity:

collection.valid_from ≥ unit.valid_from
collection.valid_to ≤ unit.valid_to (if unit dissolved)

Custody transfer continuity:

IF collection_v1.valid_to = T1
THEN collection_v2.valid_from IN [T1, T1+1 day]

Provenance notes required:

IF managing_unit changes
THEN provenance_note MUST document reason

Bidirectional Consistency

Rule: Forward and reverse relationships must match

IF collection.managing_unit = unit_id
THEN unit.managed_collections MUST include collection_id

Implementation: Validation script in Phase 5
