 description: "The organizational type classification of a heritage custodian within the \nGLAMORCUBESFIXPHDNT taxonomy (19\
-  \ categories).\n\n**Three-Layer Ontology Alignment**:\n\n1. **W3C Organization Ontology** (PRIMARY):\n   - `org:classification`\
-  \ - Standard property for organizational taxonomies\n   - Domain: org:Organization\n   - Range: skos:Concept\n   - Definition:\
-  \ \"Indicates a classification for this Organization within some \n     classification scheme. Extension vocabularies may\
-  \ wish to specialize this \n     property to have a range corresponding to a specific skos:ConceptScheme.\"\n   - Source:\
-  \ `/data/ontology/org.rdf`\n\n2. **CIDOC-CRM** (DOMAIN-SPECIFIC):\n   - `crm:P2_has_type` - Cultural heritage domain type\
-  \ assignment\n   - Domain: crm:E1_CRM_Entity\n   - Range: crm:E55_Type\n   - Definition: \"This property allows sub typing\
-  \ of CRM entities through the \n     use of a terminological hierarchy or thesaurus.\"\n   - Source: `/data/ontology/CIDOC_CRM_v7.1.3.rdf`\n\
-  \n3. **Schema.org** (WEB DISCOVERABILITY):\n   - `schema:additionalType` - Wikidata entity linking\n   - Range: schema:URL\n\
-  \   - Definition: \"An additional type for the item, typically used for adding \n     more specific types from external\
-  \ vocabularies.\"\n   - Source: `/data/ontology/schemaorg.owl`\n\n**Why org:classification is Primary**:\n- ✅ Standard W3C\
-  \ vocabulary widely adopted in public sector\n- ✅ SKOS-based with taxonomic hierarchies (skos:broader, skos:narrower)\n\
-  - ✅ Extension-friendly for domain-specific classification schemes\n- ✅ Already used in heritage sector (ROV uses rov:orgType\
-  \ as subproperty)\n- ✅ More semantically precise than crm:P2_has_type (which applies to ALL CRM entities)\n\n**Why crm:P2_has_type\
-  \ is Secondary**:\n- Used for cultural heritage domain modeling alignment\n- Supports E17_Type_Assignment for provenance\
-  \ of classification\n- Broader scope (applies to E1_CRM_Entity, not just organizations)\n\n**Why schema:additionalType is\
-  \ Tertiary**:\n- Enables web discoverability and SEO optimization\n- Links to Wikidata Q-numbers for Linked Open Data integration\n\
-  - Supports multiple simultaneous type assertions\n\n**GLAMORCUBESFIXPHDNT Taxonomy (19 Types)**:\n- **G** - GALLERY: Art\
-  \ gallery or exhibition space\n- **L** - LIBRARY: Library (public, academic, specialized)\n- **A** - ARCHIVE: Archive (government,\
-  \ corporate, personal)\n- **M** - MUSEUM: Museum (art, history, science, etc.)\n- **O** - OFFICIAL_INSTITUTION: Government\
-  \ heritage agencies\n- **R** - RESEARCH_CENTER: Research institutes and documentation centers\n- **C** - COMMERCIAL: Corporate\
-  \ heritage collections\n- **U** - UNSPECIFIED: Institution type unknown (data quality flag)\n- **B** - BIO_CUSTODIAN: Botanical\
-  \ gardens, zoos, aquariums\n- **E** - EDUCATION_PROVIDER: Universities, schools with collections\n- **S** - HERITAGE_SOCIETY:\
-  \ Historical societies, collecting societies\n- **F** - FEATURE_CUSTODIAN: Geographic features AS custodians (special case)\n\
-  - **I** - INTANGIBLE_HERITAGE_GROUP: Folklore, oral history organizations\n- **X** - MIXED: Multiple simultaneous types\n\
-  - **P** - PERSONAL_COLLECTION: Private collectors\n- **H** - HOLY_SACRED_SITE: Religious sites with heritage collections\n\
-  - **D** - DIGITAL_PLATFORM: Online archives, digital libraries\n- **N** - NON_PROFIT: NGOs, heritage advocacy organizations\n\
-  - **T** - TASTE_SCENT_HERITAGE: Culinary, olfactory heritage preservation\n\n**RDF Serialization Example**:\n```turtle\n\

-  \ \"Q207694\" .\n```\n\n**Relationship to CustodianLegalStatus**:\n- custodian_type (on Custodian): OPERATIONAL type classification\n\
-  \  (how the organization functions in the heritage ecosystem)\n- legal_form (on CustodianLegalStatus): LEGAL registration\
-  \ type\n  (ISO 20275 codes: foundation, association, corporation, government agency)\n\n**Example - Dutch Foundation Operating\
-  \ Art Museum**:\n```yaml\nCustodian:\n  hc_id: \"https://nde.nl/ontology/hc/nl-nh-ams-m-sm-q621531\"\n  custodian_type:\

-  \  # Stichting (foundation)\n```\n\n**Special Case - FEATURE_CUSTODIAN**:\nThis is the ONLY CustodianType that ALSO links\
-  \ to FeaturePlace. Used when the\nheritage custodian IS a geographic feature (e.g., historic mansion as museum).\n```yaml\n\

       **Vital Status Tracking**:
       Heritage institutions often need to track the vital status of staff members for:
       - Biographical documentation
       - Commemorative purposes
       - Historical research
       - Provenance research (who handled collections when)
-      
-      **RELATIONSHIP TO martyred**:
-      - `deceased: true` - Person has died (any cause)
-      - `martyred: true` - Person died due to conflict/persecution (implies deceased)
-      - `deceased: false` - Person is living (cannot have martyred: true)
-      
+
       **Temporal Documentation**:
       When `deceased: true`, use the associated `date_of_death` slot (TimeSpan)
       to document when the death occurred. The TimeSpan allows for uncertainty:
       - Known date: begin_of_the_begin == end_of_the_end
       - Uncertain: Provide bounds for the date range
-      
-      **Schema.org Alignment**:
-      Maps to schema:deathDate concept. The boolean flag indicates status,
-      while TimeSpan provides the actual date(s).
-      
+
       **Privacy Considerations**:
       - For recently deceased individuals, verify with institution before publishing
       - Public figures and historical staff can generally be documented

       **Semantic Meaning**:
-      
+
       This slot captures the relationship between an archive (the custodian)
       and the society/association that created/owns the archival records.
       The parent society is the provenance agent - the organization whose
       activities generated the records now held by the archive.

-        responsible for its creation, accumulation or use."
-      
+
       **Use Case**:
-      
+
       An AssociationArchive holds records OF a heritage society. The archive
       is the custodian; the society is the provenance agent whose activities
       are documented in the records.
-      
-      **Example**:
-      ```yaml
