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 → 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\
|
|
\ → 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,\n\
|
|
just 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\

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 → has_or_had_auxiliary_entities for AuxiliaryDigitalPlatform sites (project portals, microsites, APIs)'
|
|
- Hierarchical pattern mirrors CustodianName → CustodianAppellation relationship
