Session Summary: Comprehensive Slot Usage Mappings - COMPLETE ✅

Date: 2025-11-21
Session Type: Ontology Mapping - Slot Usage (Session 8)
Status: ✅ COMPLETE - All classes have slot_usage blocks
Schema Version: v0.2.2-custodian

Executive Summary

MISSION ACCOMPLISHED: The Heritage Custodian schema now has comprehensive slot_usage blocks in all 7 classes, defining precise ontology property mappings for every slot within its class context.

Key Achievement

Before: Generic slot_uri mappings only (abstract property definitions)

# Global slot definition only
slots:
  id:
    slot_uri: dcterms:identifier  # Too generic!

After: Class-specific slot_usage blocks (concrete ontology constraints)

# Class-specific property mapping
Custodian:
  class_uri: crm:E39_Actor
  slot_usage:
    id:
      slot_uri: crm:P1_is_identified_by  # CIDOC-CRM actor identification!
      description: "Links E39_Actor → E42_Identifier"

Ontology Integration Patterns

Pattern 1: CIDOC-CRM Actor Identification

Problem: Generic dcterms:identifier doesn't capture CIDOC-CRM actor identification semantics.

Solution: Use crm:P1_is_identified_by with domain/range constraints.

Custodian:
  class_uri: crm:E39_Actor
  slot_usage:
    id:
      slot_uri: crm:P1_is_identified_by  # Domain: E39_Actor, Range: E42_Identifier
      description: "CIDOC-CRM: P1 identifies actors with unique identifiers"

RDF Output:

<https://w3id.org/heritage/custodian/nl/rijksmuseum>
  a crm:E39_Actor ;
  crm:P1_is_identified_by <https://w3id.org/heritage/custodian/nl/rijksmuseum> ;
  crm:P1_is_identified_by [
    a crm:E42_Identifier ;
    crm:P2_has_type <http://id.loc.gov/vocabulary/identifiers/isil> ;
    rdf:value "NL-AmRMA"
  ] .

Pattern 2: PROV-O Entity Derivation

Problem: Observations must link to source documents AND derived entities.

Solution: Use PROV-O provenance properties with explicit semantics.

CustodianObservation:
  class_uri: heritage:CustodianObservation
  slot_usage:
    source:
      slot_uri: prov:hadPrimarySource  # Links Entity → Source (E73_Information_Object)
      description: "PROV-O: hadPrimarySource links Entity to original information source"
      required: true
    derived_from_entity:
      slot_uri: prov:wasDerivedFrom  # Links Observation → Reconstruction
      description: "PROV-O: wasDerivedFrom establishes derivation chain"

RDF Output:

<https://w3id.org/heritage/observation/rijks-letterhead-2015>
  a heritage:CustodianObservation, prov:Entity ;
  prov:hadPrimarySource <https://example.org/source/rijks-letterhead-2015.pdf> ;
  prov:wasDerivedFrom <https://w3id.org/heritage/org/rijksmuseum> ;
  skos:prefLabel "Rijks"@nl .

Pattern 3: GLEIF Legal Forms

Problem: Legal form codes (ISO 20275) need semantic links to GLEIF ontology.

Solution: Use org:classification with GLEIF ELF ConceptScheme.

CustodianReconstruction:
  slot_usage:
    legal_form:
      slot_uri: org:classification  # W3C Org classification
      description: "Maps to gleif-elf:EntityLegalForm (ISO 20275)"
      range: string
      pattern: "^[A-Z0-9]{4}$"

RDF Output:

<https://w3id.org/heritage/org/rijksmuseum>
  a heritage:CustodianReconstruction, crm:E40_Legal_Body ;
  org:classification gleif-elf:ELF-V44D ;  # Dutch stichting
  gleif-elf:hasEntityLegalFormCode "V44D" ;
  cpov:legalName "Stichting Rijksmuseum"@nl .

Pattern 4: Name Versioning (Schema.org Temporal Validity)

Problem: Custodian names change over time; need versioning.

Solution: Use Schema.org temporal validity with Dublin Core replacement relations.

CustodianName:
  slot_usage:
    valid_from:
      slot_uri: schema:validFrom  # Validity start date
    valid_to:
      slot_uri: schema:validUntil  # Validity end date
    supersedes:
      slot_uri: dcterms:replaces  # Replacement relationship

RDF Output:

<https://w3id.org/heritage/name/mauritshuis-current>
  a heritage:CustodianName ;
  skos:prefLabel "Mauritshuis"@nl ;
  schema:validFrom "2013-01-01"^^xsd:date ;
  dcterms:replaces <https://w3id.org/heritage/name/mauritshuis-old> .

<https://w3id.org/heritage/name/mauritshuis-old>
  a heritage:CustodianName ;
  skos:prefLabel "Koninklijk Kabinet van Schilderijen"@nl ;
  schema:validFrom "1822-01-01"^^xsd:date ;
  schema:validUntil "2012-12-31"^^xsd:date ;
  dcterms:isReplacedBy <https://w3id.org/heritage/name/mauritshuis-current> .

Validation Benefits

With comprehensive slot_usage, we can now:

1. Ontology Constraint Checking

# Validate CIDOC-CRM domain/range constraints
SELECT ?custodian ?id WHERE {
  ?custodian a crm:E39_Actor .
  ?custodian crm:P1_is_identified_by ?id .
  
  # Check if ?id is an E42_Identifier
  FILTER NOT EXISTS { ?id a crm:E42_Identifier }
}
# Returns violations of CIDOC-CRM constraints

2. SPARQL Query Precision

Before (generic properties):

SELECT ?custodian ?name WHERE {
  ?custodian a crm:E39_Actor .
  ?custodian dcterms:identifier ?name .  # Too generic!
}

After (ontology-specific):

SELECT ?custodian ?name WHERE {
  ?custodian a crm:E39_Actor .
  ?custodian crm:P1_is_identified_by ?id .  # CIDOC-CRM property!
  ?id rdf:value ?name .
}

3. OWL Reasoning

With class-specific properties, OWL reasoners can:

Infer implicit relationships based on ontology axioms
Validate domain/range constraints automatically
Detect inconsistencies in instance data

What This Enables

1. Valid RDF Generation

The schema can now generate RDF with:

✅ Class-specific property URIs (not generic dcterms:*)
✅ Domain/range constraints from base ontologies
✅ Multiple ontology property assertions per slot (if needed)

2. Semantic Interoperability

Heritage custodian data can integrate seamlessly with:

CIDOC-CRM systems (museum collections, cultural heritage)
PROV-O consumers (provenance tracking, data lineage)
Schema.org crawlers (Google Dataset Search, web search engines)
GLEIF databases (legal entity identification)
RiC-O archival systems (archival finding aids, EAD exports)

3. Query Optimization

SPARQL queries can leverage:

Ontology-specific properties for precise filtering
OWL reasoning for implicit relationship inference
Domain/range constraints for validation

4. Quality Assurance

Ontology validators can check:

Property domain/range violations
Missing required properties
Inconsistent relationships

Next Steps (Future Enhancements)

Phase 1: RDF Generation (High Priority)

Regenerate RDF formats with new slot_usage mappings:

gen-owl -f ttl schemas/20251121/linkml/01_custodian_name.yaml > schemas/20251121/rdf/01_custodian_name.owl.ttl
rdfpipe schemas/20251121/rdf/01_custodian_name.owl.ttl -o nt > schemas/20251121/rdf/01_custodian_name.nt
rdfpipe schemas/20251121/rdf/01_custodian_name.owl.ttl -o jsonld > schemas/20251121/rdf/01_custodian_name.jsonld

Validate RDF output:
- Check property URIs match slot_usage declarations
- Verify domain/range constraints in generated triples

Phase 2: Instance Examples (Medium Priority)

Create example instances demonstrating slot_usage:

# schemas/20251121/examples/rijksmuseum_with_slot_usage.yaml
- id: https://w3id.org/heritage/custodian/nl/rijksmuseum
  # ... complete example using all slot_usage mappings

Validate instances against schema:

linkml-validate -s schemas/20251121/linkml/01_custodian_name.yaml \
                schemas/20251121/examples/rijksmuseum_with_slot_usage.yaml

Phase 3: SPARQL Query Suite (Medium Priority)

Create SPARQL query examples leveraging slot_usage:
- Actor identification queries (CIDOC-CRM P1)
- Provenance chain queries (PROV-O wasDerivedFrom)
- Legal form classification queries (GLEIF)
- Name versioning queries (Schema.org temporal validity)

Test queries against generated RDF:

arq --data=schemas/20251121/rdf/01_custodian_name.nt \
    --query=queries/cidoc_crm_actor_identification.sparql

Phase 4: TypeDB Translation (Low Priority)

Update TypeDB schema to reflect slot_usage patterns
Test TypeDB query equivalents of SPARQL examples

Key Learnings

1. slot_uri vs. slot_usage

Lesson: Global slot_uri is insufficient for ontology alignment.

slot_uri = Abstract property mapping (applies to all classes using slot)
slot_usage = Concrete property mapping (class-specific, ontology-aware)

Example:

# Global (too generic)
slots:
  id:
    slot_uri: dcterms:identifier

# Class-specific (ontology-aware)
Custodian:
  slot_usage:
    id:
      slot_uri: crm:P1_is_identified_by  # CIDOC-CRM actor pattern

2. Domain/Range Awareness

Lesson: Ontology properties have semantic constraints.

CIDOC-CRM P1_is_identified_by requires domain E39_Actor and range E42_Identifier
PROV-O wasGeneratedBy requires domain Entity and range Activity
W3C Org subOrganizationOf requires domain and range Organization

Benefit: Explicit slot_usage enables automatic constraint validation.

3. Multiple Ontology Support

Lesson: Same slot can map to different ontologies in different classes.

Example:

# Observation (PROV-O Entity)
CustodianObservation:
  slot_usage:
    id:
      slot_uri: dcterms:identifier  # Generic for Entity

# Reconstruction (CIDOC-CRM Actor)
Custodian:
  slot_usage:
    id:
      slot_uri: crm:P1_is_identified_by  # Actor-specific

4. Documentation is Critical

Lesson: slot_usage descriptions should explain ontology context.

Good:

id:
  slot_uri: crm:P1_is_identified_by
  description: >-
    Unique identifier for this custodian.
    In CIDOC-CRM: P1_is_identified_by links E39_Actor to E42_Identifier.

Bad:

id:
  slot_uri: crm:P1_is_identified_by
  description: "Identifier"  # No ontology context!
