description: "Digital platform or online system associated with a heritage custodian.\n\n**CRITICAL DISTINCTION**:\n\n**DigitalPlatform CLASS** (this class):\n- Represents the DIGITAL INFRASTRUCTURE of any custodian\n- Used by PHYSICAL institutions (museums, archives, libraries) to represent their websites\n- Used by DIGITAL-FIRST institutions to represent their primary platform\n- Examples: Rijksmuseum website, museum online catalog, archive digital portal\n\n**DigitalPlatformType** (custodian type):\n- Classification for DIGITAL-FIRST custodians (online-only, no physical building)\n- Example: Europeana (aggregation platform), Internet Archive (born-digital)\n\n**Decision Rules**:\n\n1. **Physical Institution with Website**:\n - Custodian.custodian_type = MUSEUM/ARCHIVE/LIBRARY (not DIGITAL_PLATFORM)\n - Custodian.digital_platform \u2192 DigitalPlatform instance (this class)\n - Example: Rijksmuseum (MUSEUM) has Rijksstudio (DigitalPlatform)\n\n2. **Digital-First Institution**:\n\
\ - Custodian.custodian_type = DIGITAL_PLATFORM (DigitalPlatformType)\n - Custodian.digital_platform \u2192 DigitalPlatform instance (primary platform)\n - Example: Europeana (DIGITAL_PLATFORM) operates at https://europeana.eu/\n\n**Relationship to Custodian Hub**:\n\nDigitalPlatform is DIRECTLY connected to Custodian via refers_to_custodian,\njust like CustodianPlace, CustodianName, and CustodianLegalStatus.\n\nThis allows modeling:\n- Multiple digital platforms per custodian (website + API + mobile app)\n- Platform evolution over time (temporal validity)\n- Platform features and technical capabilities\n- Access points for digital heritage\n\n- Schema.org: schema:WebSite (primary), schema:WebApplication\n- DCAT: dcat:Catalog (for aggregation platforms), dcat:DataService (for APIs)\n- FOAF: foaf:homepage, foaf:Document\n- CIDOC-CRM: crm:E73_Information_Object (digital objects)\n\n**Example - Physical Museum with Digital Platform**:\n```yaml\nCustodian:\n has_or_had_identifier: \"https://nde.nl/ontology/hc/nl-nh-ams-m-rm-q190804\"\

comments:
- DigitalPlatform is DIRECTLY linked to Custodian hub (not a subclass of CustodianObservation)
- Used by BOTH physical institutions (website) and digital-first custodians (primary platform)
- 'Multivalued on Custodian: one custodian can have multiple platforms (website + API + mobile app)'
- Temporal validity tracks platform lifecycle (launch, shutdown, migration)
- IIIF and linked data flags enable discovery of interoperable platforms
- "MIGRATED: auxiliary_platforms \u2192 has_or_had_auxiliary_entities for AuxiliaryDigitalPlatform sites (project portals, microsites, APIs)"
- "Hierarchical pattern mirrors CustodianName \u2192 CustodianAppellation relationship"
