kempersc 6da794ee38 feat: Introduce new slots and classes for enhanced heritage data modeling 
- Added `has_or_had_place_of_birth` slot to capture structured birth place information with historical context.
- Introduced `has_or_had_quantity` slot for capturing quantified values with units and provenance.
- Created `has_or_had_service_area` slot to define geographic service areas for heritage custodians.
- Implemented `is_or_was_approximate` slot to indicate uncertainty in values (dates, quantities).
- Added `is_or_was_asserted_by` slot to track the agent responsible for assertions.
- Introduced `Asserter` class to model agents making assertions, including types like human, automated, and AI.
- Created `Quantity` class to represent quantified values with optional units and types.
- Added enums for `AsserterTypeEnum` and `QuantityTypeEnum` to standardize types of asserters and quantities.
- Archived outdated slots and replaced them with new structured alternatives following RiC-O conventions.

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\
- 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 hc_id: \"https://nde.nl/ontology/hc/nl-nh-ams-m-rm-q190804\"\n preferred_label: \"Rijksmuseum\"\
\n custodian_type: MUSEUM # Physical institution\n digital_platform:\n - platform_name: \"Rijksmuseum Website\"\
\n homepage_web_address: \"https://www.rijksmuseum.nl/\"\n platform_type: DISCOVERY_PORTAL\n iiif_support:\

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
