- Created SHACL shapes for validating temporal consistency and bidirectional relationships in custodial collections and staff observations. - Implemented a Python script to validate RDF data against the defined SHACL shapes using the pyshacl library. - Added command-line interface for validation with options for specifying data formats and output reports. - Included detailed error handling and reporting for validation results.

|
## Overview
|
|
|
|
Successfully implemented the **FeaturePlace** LinkML schema class and enum to provide physical feature type classification for nominal place references in the Heritage Custodian Ontology.
|
|
|
|
### Conceptual Model
|
|
|
|
**CustodianPlace** + **FeaturePlace** = Complete Place Description
|
|
|
|
- **CustodianPlace**: WHERE (nominal reference)
|
|
- "Rijksmuseum" - the place name
|
|
- "het herenhuis in de Schilderswijk" - nominal reference
|
|
- Represents HOW people refer to a custodian through place
|
|
|
|
- **FeaturePlace**: WHAT TYPE (classification)
|
|
- MUSEUM - the building type
|
|
- MANSION - the structure type
|
|
- Classifies the physical feature type of that place
|
|
|
|
### Architecture

|
|
|

|
CustodianPlace (crm:E53_Place)

FeaturePlace (crm:E27_Site)

|
**Location**: `schemas/20251121/linkml/modules/classes/CustodianPlace.yaml`
|
|
|
|
**Changes**:
|
|

|
|
|
|
**New Slot Definition**:

|
slot_uri: dcterms:type
|
|
description: >-
|
|
Physical feature type classification for this place (OPTIONAL).
|
|
|
|
Links to FeaturePlace which classifies WHAT TYPE of physical feature this place is.
|
|
|
|
Examples:
|
|
- "Rijksmuseum" (place name) → MUSEUM (feature type)
|
|
- "het herenhuis" → MANSION (feature type)
|
|
- "de kerk op het Damrak" → PARISH_CHURCH (feature type)
|
|
range: FeaturePlace
|
|
required: false
|
|
```
|
|
|
|
**Enhanced Example**:
|
|
```yaml
|
|
CustodianPlace:
|
|
place_name: "Rijksmuseum"
|
|
place_language: "nl"
|
|
place_specificity: BUILDING
|
|
has_feature_type: # ← NEW!
|
|
feature_type: MUSEUM
|
|
feature_name: "Rijksmuseum building"
|
|
feature_description: "Neo-Gothic museum building designed by P.J.H. Cuypers (1885)"
|
|
feature_note: "Rijksmonument, national heritage building"
|
|
refers_to_custodian: "https://nde.nl/ontology/hc/nl-nh-ams-m-rm-q190804"
|
|
```

|
## Integration Points
|
|
|
|
### 1. CustodianPlace → FeaturePlace
|
|
**Relationship**: `has_feature_type` (optional)
|
|
**Cardinality**: 0..1 (a place may have zero or one feature type classification)
|
|
**Purpose**: Adds typological classification to nominal place references
|
|
|
|
### 2. FeaturePlace → CustodianPlace
|
|
**Relationship**: `classifies_place` (required)
|
|
**Cardinality**: 1 (every feature type classification must classify a place)
|
|
**Purpose**: Links classification back to nominal reference
|
|
|
|
### 3. FeaturePlace → CustodianObservation
|
|
**Relationship**: `was_derived_from` (required)
|
|
**Cardinality**: 1..* (derived from one or more observations)
|
|
**Purpose**: Provenance tracking for classification
|
|
|
|
### 4. FeaturePlace → ReconstructionActivity
|
|
**Relationship**: `was_generated_by` (optional)
|
|
**Cardinality**: 0..1 (may or may not have reconstruction activity)
|
|
**Purpose**: Tracks formal reconstruction process
|

## Use Cases
|
|
|
|
### Use Case 1: Museum Building Classification
|
|
```yaml
|
|
# Nominal place reference
|
|
CustodianPlace:
|
|
id: place-rijksmuseum-001
|
|
place_name: "Rijksmuseum"
|
|
place_specificity: BUILDING
|
|
has_feature_type: feature-rijksmuseum-museum-001
|
|
|
|
# Physical feature type
|
|
FeaturePlace:
|
|
id: feature-rijksmuseum-museum-001
|
|
feature_type: MUSEUM
|
|
feature_description: "Neo-Gothic museum building (1885)"
|
|
classifies_place: place-rijksmuseum-001
|
|
```
|
|
|
|
### Use Case 2: Historic Mansion
|
|
```yaml
|
|
# Nominal place reference
|
|
CustodianPlace:
|
|
id: place-herenhuis-schilderswijk-001
|
|
place_name: "het herenhuis in de Schilderswijk"
|
|
place_specificity: NEIGHBORHOOD
|
|
has_feature_type: feature-herenhuis-mansion-001
|
|
|
|
# Physical feature type
|
|
FeaturePlace:
|
|
id: feature-herenhuis-mansion-001
|
|
feature_type: MANSION
|
|
feature_description: "17th-century canal mansion with ornate gable"
|
|
classifies_place: place-herenhuis-schilderswijk-001
|
|
```
|
|
|
|
### Use Case 3: Church Archive
|
|
```yaml
|
|
# Nominal place reference
|
|
CustodianPlace:
|
|
id: place-oude-kerk-001
|
|
place_name: "Oude Kerk Amsterdam"
|
|
place_specificity: BUILDING
|
|
has_feature_type: feature-oude-kerk-church-001
|
|
|
|

|
|
classifies_place: place-oude-kerk-001
|
|
```
|
|
|

|
|
|
|
## Ontology Alignment
|
|
|
|
### CIDOC-CRM Mapping
|
|
- **CustodianPlace** → `crm:E53_Place` (conceptual place)
|
|
- **FeaturePlace** → `crm:E27_Site` (physical site/feature)
|
|
|
|
**Rationale**:
|
|
- E53_Place: "Extent in space, in particular on the surface of the earth"
|
|
- E27_Site: "Geometrically defined place that is known at that location" (subclass of E53)
|
|
|
|
### Schema.org Mapping
|
|
- **CustodianPlace** → `schema:Place` (generic place)
|
|
- **FeaturePlace** → `schema:LandmarksOrHistoricalBuildings` (heritage buildings)
|
|
|
|
**Rationale**:
|
|
- LandmarksOrHistoricalBuildings: "An historical landmark or building"
|
|
- Aligns with Type F (FEATURES) in GLAMORCUBESFIXPHDNT taxonomy
|
|

|
|
|
|
## Testing Recommendations
|
|
|
|
### Unit Tests
|
|
1. **Enum validation**: All 298 values parse correctly
|
|
2. **Required fields**: `feature_type`, `classifies_place`, `was_derived_from`
|
|
3. **Optional fields**: Handle null values gracefully
|
|
4. **Wikidata Q-numbers**: All resolve to real entities
|
|
|
|
### Integration Tests
|
|
1. **CustodianPlace ↔ FeaturePlace**: Bidirectional links work
|
|
2. **FeaturePlace → CustodianObservation**: Provenance tracking
|
|
3. **Temporal validity**: `valid_from`/`valid_to` constraints
|
|
4. **RDF serialization**: Correct ontology class URIs
|
|
|
|
### Example Test Cases
|
|
```python
|
|
def test_feature_place_required_fields():
|
|
"""FeaturePlace requires feature_type, classifies_place, was_derived_from"""
|
|
feature = FeaturePlace(
|
|
feature_type="MUSEUM",
|
|
classifies_place="place-001",
|
|
was_derived_from=["obs-001"]
|
|
)
|
|
assert feature.feature_type == "MUSEUM"
|
|
|
|
def test_custodian_place_optional_feature_type():
|
|
"""CustodianPlace.has_feature_type is optional"""
|
|
place = CustodianPlace(
|
|
place_name="Unknown building",
|
|
# has_feature_type=None # Optional
|
|
was_derived_from=["obs-001"],
|
|
refers_to_custodian="cust-001"
|
|
)
|
|
assert place.has_feature_type is None # ✓ Valid
|
|
|
|
def test_invalid_feature_type():
|
|
"""FeaturePlace.feature_type must be valid enum value"""
|
|
with pytest.raises(ValidationError):
|
|
FeaturePlace(
|
|
feature_type="INVALID_TYPE", # ✗ Not in FeatureTypeEnum
|
|
classifies_place="place-001",
|
|
was_derived_from=["obs-001"]
|
|
)
|
|
```
|

|
|
## Documentation Updates
|
|
|
|
### Files to Update
|
|
1. **AGENTS.md**: Add FeaturePlace extraction workflow
|
|
2. **schemas/README.md**: Document new enum and class
|
|
3. **ontology/ONTOLOGY_EXTENSIONS.md**: Add CIDOC-CRM E27_Site mapping
|
|
4. **docs/SCHEMA_MODULES.md**: List FeatureTypeEnum and FeaturePlace
|
|
|
|
### Example Agent Prompt
|
|
```
|
|
When extracting heritage institutions from conversations:
|
|
|
|
1. Identify nominal place references (CustodianPlace)
|
|
- "Rijksmuseum" (building name as place)
|
|
- "het herenhuis in de Schilderswijk" (mansion reference)
|
|
|
|
2. Classify physical feature type (FeaturePlace)
|
|
- MUSEUM (for museum buildings)
|
|
- MANSION (for large historic houses)
|
|
- PARISH_CHURCH (for church buildings)
|
|
- MONUMENT (for memorials/statues)
|
|
- [298 other types available]
|
|
|
|
3. Link classification to place
|
|
- FeaturePlace.classifies_place → CustodianPlace
|
|
- CustodianPlace.has_feature_type → FeaturePlace (optional)
|
|
|
|
4. Record provenance
|
|
- FeaturePlace.was_derived_from → observation sources
|
|
- Include temporal validity (valid_from/valid_to) when known
|
|
```
