comments:
- Storage models the FUNCTIONAL role of preservation, not just physical location
- Links to AuxiliaryPlace for physical building/site information
- Condition observations (StorageCondition) may come from internal or external sources
- Condition policy (StorageConditionPolicy) represents designed/intended state
- Actual conditions may differ significantly from policy - this is critical for transparency
- Multiple Storage instances can exist at same AuxiliaryPlace (different zones)
- Storage models the preservation function, not only the physical building
- AuxiliaryPlace can provide location context for a storage facility
- StorageCondition captures observed state; StorageConditionPolicy captures intended state
- Multiple Storage instances can coexist in one physical site

Key distinction
- Storage: functional role of preserving collections.
- AuxiliaryPlace: physical site/building context.
- StorageCondition: observed state.
- StorageConditionPolicy: intended target conditions.
Typical use cases
- archive depot
- cold storage for film/photographic materials
- open study storage

Use this type when classification is indeterminate because evidence is
insufficient, conflicting, transitional, or genuinely outside current type
categories.
This is a data-quality/uncertainty marker and should be reviewed over time.

description: "Specialized custodian type for institutions where type classification is\nimpossible, ambiguous, or not yet determined based on available evidence.\n\n**CRITICAL DISTINCTION - Unspecified vs. Mixed vs. Other Types**:\n\n**UnspecifiedType** applies when:\n- Type CANNOT BE DETERMINED from available sources (insufficient evidence)\n- Type is AMBIGUOUS (conflicting evidence about institutional function)\n- Type is IN TRANSITION (institution changing but new type not yet clear)\n- Institution DOES NOT FIT existing categories (genuinely novel type)\n\n**Do NOT use UnspecifiedType if**:\n- \u274C Institution clearly fits a type but you haven't classified yet \u2192 Classify it!\n- \u274C Institution operates as multiple types \u2192 Use MixedCustodianType (X code)\n- \u274C You're just unsure \u2192 Research further before defaulting to Unspecified\n\n**UnspecifiedType is a DATA QUALITY FLAG, not a permanent classification.**\n\n**When to Use Unspecified (U code)**:\n\n1. **Insufficient\
\ Evidence** - Cannot determine type from available sources:\n - Mentioned in passing without functional description\n - Only name available (e.g., \"Heritage Organization of XYZ\")\n - Historical reference without context\n - Defunct organization with no surviving documentation\n\n2. **Ambiguous Evidence** - Conflicting information about institutional function:\n - Called \"museum\" but operates as archive\n - Described as \"cultural center\" without specifics\n - Multiple sources disagree on type\n - Self-description ambiguous or generic\n\n3. **Transitional Status** - Institution changing type:\n - In process of merger/reorganization\n - Converting from one type to another\n - Temporary closure/restructuring\n - New institution not yet operational\n\n4. **Novel Type** - Genuinely doesn't fit existing categories:\n - Emerging heritage forms (e.g., cryptocurrency heritage)\n - Hybrid types not covered by taxonomy\n - Experimental heritage models\n -\
\ Indigenous heritage governance not matching Western categories\n\n1. **Structural Layer** (W3C Standards):\n - skos:Concept - Thesaurus classification\n - prov:Entity - Provenance tracking for data quality\n\n2. **Domain Layer** (Heritage Ontologies):\n - crm:E74_Group - CIDOC-CRM social group (generic organization)\n - schema:Organization - Generic organizational entity\n\n3. **Web Layer** (Schema.org):\n - schema:Organization - Generic organization (no specific type)\n - schema:Thing - Fallback for truly unclassifiable\n\n**Wikidata Coverage** (15+ unspecified heritage entities):\n\nGeneric Heritage Organizations:\n- Q163740 (cultural organization) - Broad heritage category\n- Q7241077 (heritage organization) - Generic heritage entity\n- Q105558717 (cultural institution) - Unspecified cultural entity\n- Q215380 (heritage preservation organization) - Function unclear\n\nDefunct Organizations with Limited Documentation:\n- Q105558717 (historical heritage society - defunct\
\ 1920s)\n- Q5879427 (former cultural center - no surviving records)\n- Q215380 (heritage group - mentioned only in newspaper)\n\nTransitional Institutions:\n- Q163740 (institution under reorganization)\n- Q5283639 (merger in progress - final type TBD)\n- Q7241077 (new institution in planning phase)\n\n**Key Distinctions from Other Types**:\n\nvs. MixedCustodianType:\n- UnspecifiedType: Type CANNOT BE DETERMINED (data quality issue)\n- MixedType: Multiple types ARE KNOWN (multivalued custodian_type)\n- Example: \"Heritage Organization of Amsterdam\" (unknown) vs. Stadsarchief (archive + museum)\n\nvs. NonProfitType:\n- UnspecifiedType: FUNCTION unknown (even if non-profit status is clear)\n- NonProfit: FUNCTION known = heritage advocacy/services\n- Example: \"Cultural Foundation X\" (function unclear) vs. Europa Nostra (advocacy)\n\nvs. OfficialInstitution:\n- UnspecifiedType: Government agency but FUNCTION unknown\n- OfficialInstitution: Government REGULATION/POLICY role is clear\n\
- Example: \"Ministry of Culture Department Y\" (function unclear) vs. National Heritage Agency\n\nvs. All Specific Types:\n- UnspecifiedType: DEFAULT when classification is impossible\n- Specific Types: Use ONLY when evidence supports classification\n- Example: Institution mentioned once without context vs. \"Rijksmuseum\"\n\n**Data Quality Workflow**:\n\nWhen encountering potential UnspecifiedType:\n\n1. **Research first** - Check:\n - Institutional website\n - Wikidata entry\n - Professional directories (e.g., ICOM, ICA, IFLA)\n - Historical sources\n - Contact information\n\n2. **Document uncertainty** - Record in provenance:\n - Why type could not be determined\n - What information would resolve uncertainty\n - When classification was attempted\n - What sources were consulted\n\n3. **Flag for review** - Mark record:\n - needs_verification: true\n - review_reason: \"Insufficient evidence to determine type\"\n - confidence_score: < 0.5\n\n4. **Re-evaluate\
\ periodically** - Unspecified is TEMPORARY:\n - Check for new sources (websites, publications)\n - Query heritage networks\n - Request information from institution\n - Update classification when evidence emerges\n\n**RDF Serialization Example**:\n\n```turtle\n@prefix hc: <https://nde.nl/ontology/hc/> .\n@prefix skos: <http://www.w3.org/2004/02/skos/core#> .\n@prefix schema: <http://schema.org/> .\n@prefix prov: <http://www.w3.org/ns/prov#> .\n@prefix dcterms: <http://purl.org/dc/terms/> .\n\nhc:UnspecifiedType\n a skos:Concept, hc:CustodianType ;\n skos:prefLabel \"Unspecified Type\"@en,\n \"Ongespecificeerd Type\"@nl,\n \"Nicht spezifizierter Typ\"@de,\n \"Type Non Sp\xE9cifi\xE9\"@fr ;\n skos:definition \"Heritage custodians where type cannot be determined\"@en ;\n skos:broader hc:CustodianType ;\n schema:url <https://nde.nl/ontology/hc/class/unspecified-type> .\n\n# Example: Historical Heritage Society of XYZ (defunct,\
