- 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 Feature Complete
|
|
|
|
**Date**: 2025-11-22 19:30 UTC
|
|
**Schema Version**: 0.4.0
|
|
**Status**: ✅ **COMPLETE**
|
|
|
|
---
|
|
|
|
## What Was Done
|
|
|
|
Added **OrganizationalStructure** class to model informal operational units (departments, teams, labs) in heritage institutions.
|
|
|
|
### Key Additions:
|
|
- **Class**: OrganizationalStructure (220 lines) → `org:OrganizationalUnit`
|
|
- **Enum**: OrganizationalUnitTypeEnum (9 types: DEPARTMENT, TEAM, DIVISION, GROUP, PROGRAM, SERVICE, LAB, OFFICE, UNIT)
|
|
- **Slots**: 6 new slots (unit_name, unit_type, parent_unit, staff_count, contact_point, refers_to_custodian)
|
|
- **Integration**: Added `organizational_structure` slot to Custodian class
|
|
|
|
### Files Changed:
|
|
- **Created**: 8 files (1 class, 1 enum, 6 slots)
|
|
- **Modified**: 2 files (Custodian.yaml, main schema)
|
|
- **Generated**: RDF/OWL (190 KB), ER diagram (6.3 KB)
|
|
- **Documented**: 2 comprehensive guides (~20,000 words)
|
|

## Critical Distinction
|
|
|
|
**GovernanceStructure** vs. **OrganizationalStructure**:
|
|
|
|
| Aspect | GovernanceStructure | OrganizationalStructure |
|
|
|--------|---------------------|-------------------------|
|
|
| Location | On `CustodianLegalStatus` | On `Custodian` |
|
|
| Scope | FORMAL (legal docs) | INFORMAL (org charts) |
|
|
| Example | "Agency under Ministry OCW" | "Digital Preservation Team" |
|
|
| Changes | Requires legal process | Internal operational |
|
|
|
|
**Use both together** - they're complementary, not competitive.
|

|
|
## Key Features
|
|
|
|
### 1. Hierarchical Nesting
|
|
```yaml
|
|
organizational_structure:
|
|
- unit_name: "Collections Care Division" # Level 1
|
|
unit_type: "DIVISION"
|
|
|
|
- unit_name: "Conservation Department" # Level 2
|
|
parent_unit:
|
|
unit_name: "Collections Care Division"
|
|
|
|
- unit_name: "Paper Conservation Lab" # Level 3
|
|
parent_unit:
|
|
unit_name: "Conservation Department"
|
|
```
|
|
|
|
### 2. Temporal Validity
|
|
```yaml
|
|
# Dissolved unit
|
|
- unit_name: "Restoration Department"
|
|
valid_from: "1885-07-13"
|
|
valid_to: "2013-03-31" # ← Reorganization
|
|
|
|
# Successor unit
|
|
- unit_name: "Conservation and Research Department"
|
|
valid_from: "2013-04-01" # ← Replacement
|
|
```
|
|
|
|
### 3. Cross-Functional Groups
|
|
```yaml
|
|
- unit_name: "Metadata Standards Working Group"
|
|
unit_type: "GROUP"
|
|
staff_count: 0 # ← Cross-functional, no dedicated staff
|
|
```
|
|
|
|
---
|
|
|
|
## Validation Status
|
|
|
|
- ✅ **Schema compiles** (gen-owl successful)
|
|
- ✅ **RDF generates** (190 KB Turtle, valid triples)
|
|
- ✅ **ER diagram correct** (relationships verified)
|
|
- ⚠️ **Instance validation** needs tree_root container (deferred)
|
|
|

|
|
|
|
## Example Use Cases
|
|
|
|
1. **National Archives**: 3-level hierarchy (Division → Department → Lab)
|
|
2. **Rijksmuseum**: Temporal reorganization (dissolved + successor units)
|
|
3. **University Library**: Cross-functional working groups
|
|
4. **Small Archives**: Flat structure (no nesting)
|
|
5. **BnF**: Multilingual units (French names preserved)
|

|
## Next Steps (If Continuing)
|
|
|
|
### Immediate (Phase 2)
|
|
1. **Fix instance validation** - Configure tree_root container class
|
|
2. **Create change events** - OrganizationalChangeEvent class for mergers
|
|
3. **Add more examples** - Edge cases, international institutions
|
|
|
|
### Medium-Term (Phase 3)
|
|
1. **PiCo integration** - Link staff roles to units
|
|
2. **Collection-department mapping** - CustodianCollection.custodian_department
|
|
3. **Validation rules** - SHACL constraints for data quality
|
|
|
|
### Long-Term (Phase 4)
|
|
1. **Budget allocation** - Financial data per unit
|
|
2. **Performance metrics** - KPIs and analytics
|
|
3. **Workflow modeling** - Inter-unit process flows
|
