 # Rule 51: No Hallucinated Ontology References
 **Priority**: CRITICAL  
 **Scope**: All LinkML schema files (`schemas/20251121/linkml/`)  
 **Created**: 2025-01-13
 ---
 ## Summary
 All ontology references in LinkML schema files (`class_uri`, `slot_uri`, `*_mappings`) MUST be verifiable against actual ontology files in `/data/ontology/`. References to predicates or classes that do not exist in local ontology files are considered **hallucinated** and are prohibited.
 ---
 ## The Problem
 AI agents may suggest ontology mappings based on training data without verifying that:
 1. The ontology file exists in `/data/ontology/`
 2. The specific predicate/class exists within that ontology file
 3. The prefix is declared and resolvable
 This leads to schema files containing references like `dqv:value` or `adms:status` that cannot be validated or serialized to RDF.
 ---
 ## Requirements
 ### 1. All Ontology Prefixes Must Have Local Files
 Before using a prefix (e.g., `prov:`, `schema:`, `org:`), verify the ontology file exists:
 ```bash
 # Check if ontology exists
 ls data/ontology/ | grep -i "prov\|schema\|org"
 ```
 **Available Ontologies** (as of 2025-01-13):
 | Prefix | File | Verified |
 |--------|------|----------|
 | `prov:` | `prov-o.ttl`, `prov.ttl` | ✅ |
 | `schema:` | `schemaorg.owl` | ✅ |
 | `org:` | `org.rdf` | ✅ |
 | `skos:` | `skos.rdf` | ✅ |
 | `dcterms:` | `dublin_core_elements.rdf` | ✅ |
 | `foaf:` | `foaf.ttl` | ✅ |
 | `rico:` | `RiC-O_1-1.rdf` | ✅ |
 | `crm:` | `CIDOC_CRM_v7.1.3.rdf` | ✅ |
 | `geo:` | `geo.ttl` | ✅ |
 | `sosa:` | `sosa.ttl` | ✅ |
 | `bf:` | `bibframe.rdf` | ✅ |
 | `edm:` | `edm.owl` | ✅ |
 | `premis:` | `premis3.owl` | ✅ |
 | `dcat:` | `dcat3.ttl` | ✅ |
 | `ore:` | `ore.rdf` | ✅ |
 | `pico:` | `pico.ttl` | ✅ |
 | `gn:` | `geonames_ontology.rdf` | ✅ |
 | `time:` | `time.ttl` | ✅ |
 | `locn:` | `locn.ttl` | ✅ |
 | `dqv:` | `dqv.ttl` | ✅ |
 | `adms:` | `adms.ttl` | ✅ |
 **NOT Available** (do not use without adding):
 | Prefix | Status | Alternative |
 |--------|--------|-------------|
 | `qudt:` | Only referenced in era_ontology.ttl | Use `hc:` with close_mappings annotation |
 ### 2. Predicates Must Exist in Ontology Files
 Before using a predicate, verify it exists:
 ```bash
 # Verify predicate exists
 grep -l "hasFrameRate\|frameRate" data/ontology/premis3.owl
 # Check specific predicate definition
 grep -E "premis:hasFrameRate|:hasFrameRate" data/ontology/premis3.owl
 ```
 ### 3. Use hc: Prefix for Domain-Specific Concepts
 When no standard ontology predicate exists, use the Heritage Custodian namespace:
 ```yaml
 # CORRECT - Use hc: with documentation
 slots:
  heritage_relevance_score:
    slot_uri: hc:heritageRelevanceScore
    description: Heritage sector relevance score (0.0-1.0)
    annotations:
      ontology_note: >-
        No standard ontology predicate for heritage relevance scoring.
        Domain-specific metric for this project.
 # WRONG - Hallucinated predicate
 slots:
  heritage_relevance_score:
    slot_uri: dqv:heritageScore  # Does not exist!
 ```
 ### 4. Document External References in close_mappings
 When a similar concept exists in an ontology we don't have locally, document it in `close_mappings` with a note:
 ```yaml
 slots:
  confidence_score:
    slot_uri: hc:confidenceScore
    close_mappings:
      - dqv:value  # W3C Data Quality Vocabulary (not in local files)
    annotations:
      external_ontology_note: >-
        dqv:value from W3C Data Quality Vocabulary would be semantically 
        appropriate but ontology not included in project. See 
        https://www.w3.org/TR/vocab-dqv/
 ```
 ---
 ## Verification Workflow
 ### Before Adding New Mappings
 1. **Check if ontology file exists**:
   ```bash
   ls data/ontology/ | grep -i "<ontology-name>"
   ```
 2. **Search for predicate in ontology**:
   ```bash
   grep -l "<predicate-name>" data/ontology/*
   ```
 3. **Verify predicate definition**:
   ```bash
   grep -B2 -A5 "<predicate-name>" data/ontology/<file>
   ```
 4. **If not found**: Use `hc:` prefix with appropriate documentation
 ### When Reviewing Existing Mappings
 Run validation script:
 ```bash
 # Find all slot_uri references
 grep -r "slot_uri:" schemas/20251121/linkml/modules/slots/ | \
  grep -v "hc:" | \
  cut -d: -f3 | \
  sort -u
 # Verify each prefix has a local file
 for prefix in prov schema org skos dcterms foaf rico; do
  echo "Checking $prefix:"
  ls data/ontology/ | grep -i "$prefix" || echo "  NOT FOUND!"
 done
 ```
 ---
 ## Ontology Addition Process
 If a new ontology is genuinely needed:
 1. **Download the ontology**:
   ```bash
   curl -L -o data/ontology/<name>.ttl "<url>" -H "Accept: text/turtle"
   ```
 2. **Update ONTOLOGY_CATALOG.md**:
   ```bash
   # Add entry to data/ontology/ONTOLOGY_CATALOG.md
   ```
 3. **Verify predicates exist**:
   ```bash
   grep "<predicate>" data/ontology/<name>.ttl
   ```
 4. **Update LinkML prefixes** in schema files
 ---
 ## Examples
 ### CORRECT: Verified Mapping
 ```yaml
 slots:
  retrieval_timestamp:
    slot_uri: prov:atTime  # Verified in data/ontology/prov-o.ttl
    range: datetime
 ```
 ### CORRECT: Domain-Specific with External Reference
 ```yaml
 slots:
  confidence_score:
    slot_uri: hc:confidenceScore  # HC namespace (always valid)
    range: float
    close_mappings:
      - dqv:value  # External reference (documented, not required locally)
    annotations:
      ontology_note: >-
        Uses HC namespace as dqv: ontology not in local files.
        dqv:value would be semantically appropriate alternative.
 ```
 ### WRONG: Hallucinated Mapping
 ```yaml
 slots:
  confidence_score:
    slot_uri: dqv:value  # INVALID - dqv: not in data/ontology/!
    range: float
 ```
 ### WRONG: Non-Existent Predicate
 ```yaml
 slots:
  frame_rate:
    slot_uri: premis:hasFrameRate  # INVALID - predicate not in premis3.owl!
    range: float
 ```
 ---
 ## Consequences of Violation
 1. **RDF serialization fails** - Invalid prefixes cause gen-owl errors
 2. **Schema validation errors** - LinkML validates prefix declarations
 3. **Broken interoperability** - External systems cannot resolve URIs
 4. **Data quality issues** - Semantic web tooling cannot process data
 ---
 ## PREMIS Ontology Reference (premis3.owl)
 **CRITICAL**: The PREMIS ontology is frequently hallucinated. ALL premis: references MUST be verified.
 ### Valid PREMIS Classes
 ```
 Action, Agent, Bitstream, Copyright, Dependency, EnvironmentCharacteristic,
 Event, File, Fixity, HardwareAgent, Identifier, Inhibitor, InstitutionalPolicy,
 IntellectualEntity, License, Object, Organization, OutcomeStatus, Person,
 PreservationPolicy, Representation, RightsBasis, RightsStatus, Rule, Signature,
 SignatureEncoding, SignificantProperties, SoftwareAgent, Statute,
 StorageLocation, StorageMedium
 ```
 ### Valid PREMIS Properties
 ```
 act, allows, basis, characteristic, citation, compositionLevel, dependency,
 determinationDate, documentation, encoding, endDate, fixity, governs,
 identifier, inhibitedBy, inhibits, jurisdiction, key, medium, note,
 originalName, outcome, outcomeNote, policy, prohibits, purpose, rationale,
 relationship, restriction, rightsStatus, signature, size, startDate,
 storedAt, terms, validationRules, version
 ```
 ### Known Hallucinated PREMIS Terms (DO NOT USE)
 | Hallucinated Term | Correction |
 |-------------------|------------|
 | `premis:PreservationEvent` | Use `premis:Event` |
 | `premis:RightsDeclaration` | Use `premis:RightsBasis` or `premis:RightsStatus` |
 | `premis:hasRightsStatement` | Use `premis:rightsStatus` |
 | `premis:hasRightsDeclaration` | Use `premis:rightsStatus` |
 | `premis:hasRepresentation` | Use `premis:relationship` or `dcterms:hasFormat` |
 | `premis:hasRelatedStatementInformation` | Use `premis:note` or `adms:status` |
 | `premis:hasObjectCharacteristics` | Use `premis:characteristic` |
 | `premis:rightsGranted` | Use `premis:RightsStatus` class with `premis:restriction` |
 | `premis:rightsEndDate` | Use `premis:endDate` |
 | `premis:linkingAgentIdentifier` | Use `premis:Agent` class |
 | `premis:storageLocation` (lowercase) | Use `premis:storedAt` property or `premis:StorageLocation` class |
 | `premis:hasFrameRate` | Does not exist - use `hc:frameRate` |
 | `premis:environmentCharacteristic` (lowercase) | Use `premis:EnvironmentCharacteristic` (class) |
 ### PREMIS Verification Commands
 ```bash
 # List all PREMIS classes
 grep -E "owl:Class.*premis" data/ontology/premis3.owl | \
  sed 's/.*v3\///' | sed 's/".*//' | sort -u
 # List all PREMIS properties
 grep -E "ObjectProperty|DatatypeProperty" data/ontology/premis3.owl | \
  grep -oP 'v3/\K[^"]+' | sort -u
 # Verify a specific term exists
 grep -c "YourTermHere" data/ontology/premis3.owl
 ```

 ## Implementation Notes
 ### When to Use Standard Ontology Predicates
 Use standard predicates when:
 1. **Exact semantic match exists** (e.g., `schema:name`, `dcterms:identifier`)
 2. **Well-established patterns** (e.g., `schema:startDate/endDate`)
 3. **Interoperability is primary concern**
 ### When to Use hc: Prefix
 Use domain-specific `hc:` prefix when:
 1. **No standard equivalent exists** (e.g., `hc:heritageRelevanceScore`)
 2. **Domain-specific semantics** (e.g., `hc:capacityLinearMeters`)
 3. **Boolean flags without standard equivalents**
 4. **Technical processing metrics** (e.g., `hc:diarizationConfidence`)
 ### Required Close/Related Mappings
 When using `hc:` prefix, always include appropriate mappings:
 - `close_mappings`: Similar semantics, different scope
 - `related_mappings`: Conceptually related
 - `broad_mappings`: External term is narrower
 - `narrow_mappings`: External term is broader

 ### Rule 51: No Hallucinated Ontology References
 **CRITICAL**: All ontology references (`class_uri`, `slot_uri`, `*_mappings`) MUST be verifiable against actual files in `/data/ontology/`.
 **The Problem**: AI agents may suggest predicates like `dqv:value` or `premis:hasFrameRate` without verifying they exist in local ontology files. This causes RDF serialization failures.
 **Available Ontologies** (verified 2025-01-13):
 | Prefix | File | Verified |
 |--------|------|----------|
 | `prov:` | `prov-o.ttl` | ✅ |
 | `schema:` | `schemaorg.owl` | ✅ |
 | `org:` | `org.rdf` | ✅ |
 | `skos:` | `skos.rdf` | ✅ |
 | `dcterms:` | `dublin_core_elements.rdf` | ✅ |
 | `foaf:` | `foaf.ttl` | ✅ |
 | `rico:` | `RiC-O_1-1.rdf` | ✅ |
 | `dqv:` | `dqv.ttl` | ✅ |
 | `adms:` | `adms.ttl` | ✅ |
 | `dcat:` | `dcat3.ttl` | ✅ |
 **Verification Workflow**:
 ```bash
 # 1. Check ontology file exists
 ls data/ontology/ | grep -i "<prefix>"
 # 2. Search for predicate
 grep -l "<predicate>" data/ontology/*
 ```
 **When No Standard Exists**: Use `hc:` prefix with documentation:
 ```yaml
 slots:
  heritage_relevance_score:
    slot_uri: hc:heritageRelevanceScore  # Always valid
    annotations:
      ontology_note: "No standard ontology equivalent exists"
 ```

      In Dutch naming conventions, surnames with prefixes (tussenvoegsels) like
      "van", "de", "van der", etc. are sorted by the main surname element,
      ignoring the prefix.
      This property captures just the sortable surname component:
      Examples:
      - "de Vries" → base_surname: "Vries" (sorts under V)
      - "van den Berg" → base_surname: "Berg" (sorts under B)
      - "van der Waals" → base_surname: "Waals" (sorts under W)
-
+      - "in 't Veld" → base_surname: "Veld" (sorts under V)
      - "in ''t Veld" → base_surname: "Veld" (sorts under V)
      Equivalent to BioDes:geslachtsnaam in Dutch heritage standards.
      IMPORTANT: Belgian Dutch and some international conventions may sort
      by the full surname including prefix. In those cases, use the full
      surname here or handle sorting differently in your application.
      For surnames without prefixes, base_surname equals the full surname:
      - "Jansen" → base_surname: "Jansen"
      - "Bakker" → base_surname: "Bakker"
