- Implemented `owl_to_mermaid.py` to convert OWL/Turtle files into Mermaid class diagrams. - Implemented `owl_to_plantuml.py` to convert OWL/Turtle files into PlantUML class diagrams. - Added two new PlantUML files for custodian multi-aspect diagrams.

# Quick Status: OrganizationalStructure + OrganizationalChangeEvent Complete
|
|
|
|
**Date**: 2025-11-22
|
|
**Status**: ✅ **COMPLETE** (Phase 1 + Phase 2)
|
|
**Schema Version**: v0.5.0
|
|

|
|
|
|
## What We Built (Summary)
|
|
|
|
### Phase 1: OrganizationalStructure ✅
|
|
**Purpose**: Model operational units (departments, teams, divisions)
|
|
|
|
**Key Files**:
|
|
- Class: `modules/classes/OrganizationalStructure.yaml`
|
|
- Enum: `modules/enums/OrganizationalUnitTypeEnum.yaml` (9 types)
|
|
- Slots: 6 files (unit_name, unit_type, parent_unit, etc.)
|
|
|
|
**Features**:
|
|
- Hierarchical nesting (self-referencing parent_unit)
|
|
- Temporal validity (valid_from/valid_to)
|
|
- W3C ORG alignment (`org:OrganizationalUnit`)
|
|
|
|

|
|
|
|
### Phase 2: OrganizationalChangeEvent ✅
|
|
**Purpose**: Document organizational restructuring history
|
|
|
|
**Key Files**:
|
|
- Class: `modules/classes/OrganizationalChangeEvent.yaml`
|
|
- Enum: `modules/enums/OrganizationalChangeEventTypeEnum.yaml` (9 event types)
|
|
- Slots: 9 files (event_type, event_date, affected_units, etc.)
|
|
|
|
**Event Types**:
|
|
MERGER, SPLIT, DISSOLUTION, REORGANIZATION, RENAMING, TRANSFER, FOUNDING, EXPANSION, REDUCTION
|
|
|
|
**Features**:
|
|
- Links to affected/resulting organizational units
|
|
- Documents rationale, staff impact, sources
|
|
- CIDOC-CRM Event (`crm:E5_Event`) alignment
|

## Key Design Decisions
|
|
|
|
### 1. Formal vs. Informal Distinction
|
|
- **GovernanceStructure** (on CustodianLegalStatus): LEGAL/FORMAL structure from registration
|
|
- **OrganizationalStructure** (on Custodian): OPERATIONAL/INFORMAL units for day-to-day work
|
|
|
|
### 2. Event-Structure Temporal Alignment
|
|
- Dissolved units: `valid_to` = `event_date`
|
|
- Created units: `valid_from` = `event_date`
|
|
|
|
### 3. Hub Architecture Maintained
|
|
- Both features use `refers_to_custodian` to link to Custodian hub
|
|
- Preserves hub abstraction for multi-aspect modeling
|

## Next Steps (Priority Order)
|
|
|
|
### Priority 1: PiCo Integration - Staff Role Tracking
|
|
**Goal**: Link PersonObservation to organizational units
|
|
**Timeline**: 1-2 hours
|
|
**Files**: PersonObservation.yaml, create unit_affiliation slot
|
|
|
|
### Priority 2: CustodianCollection - Department Mapping
|
|
**Goal**: Link collections to managing units
|
|
**Timeline**: 1 hour
|
|
**Files**: CustodianCollection.yaml, create custodian_department slot
|
|
|
|
### Priority 3: Validation Framework
|
|
**Goal**: Automated temporal consistency checks
|
|
**Timeline**: 2-3 hours
|
|
**Files**: Create validate_organizational_change_events.py
|
|
|
|
### Priority 4: Historical Data Enrichment
|
|
**Goal**: Extract events from annual reports
|
|
**Timeline**: 5-8 hours
|
|
**Dependencies**: Institutional data sources
|

|
|
✅ **Workforce impact analysis** - Aggregate staff changes across events
|
|
✅ **Organizational stability scoring** - Count/weight changes per custodian
|
|
✅ **Successor unit lookup** - Trace dissolved units to successors
