kempersc f622450304 Add new slots and update existing ones for heritage ontology
- Introduced new slots for administrative context, CMS categories, detected CMS, product version, co-funding requirements, co-organizers, collection access, collection dates, characteristics, class definitions, Dutch context, example locations, names, notes, and Wikidata IDs.
- Enhanced existing slots such as has_or_had_organizer and offers_or_offered_access to align with RiC-O naming conventions and improve temporal semantics.
- Migrated and restructured descriptions for clarity and consistency across various slots, ensuring alignment with Schema.org and other ontological standards.
- Implemented multivalued and inlined options for several slots to accommodate complex data structures.
- Updated annotations and examples to reflect the latest usage scenarios and best practices in the heritage sector.

Acquisition:
class_uri: crm:E8_Acquisition
description: >-
Represents an acquisition event - how and when an object or specimen was obtained for a collection.
CIDOC-CRM E8 Acquisition models the transfer of legal ownership rights.
**Key properties**:
- `temporal_extent`: When the acquisition occurred (TimeSpan with fuzzy boundaries for historical items)
- `acquisition_method`: How the item was acquired (field collection, purchase, donation, etc.)
- `acquisition_source`: From whom/where acquired (collector, dealer, previous owner, field location)
- `acquisition_agent`: Who performed the acquisition (collector, curator, institution)
**Darwin Core alignment**: For biological specimens:
- `temporal_extent` replaces `dwc:eventDate` (collection date)
- `acquisition_source` can capture `dwc:locality` and `dwc:recordedBy`
**Use cases**:
- Museum object provenance (purchase from dealer, 1923)
- Biological specimen collection (field collection, Amazon basin, 1750s)
- Archival transfer (transferred from ministry archives, 2001)
- Art donation (donated by artist's estate, 2015)

attributes:
acquisition_method:
range: AcquisitionMethodEnum
description: >-
Method by which the item was acquired (field collection, purchase, donation, etc.).
acquisition_source:
range: string
description: >-
Source from which item was acquired. Can be:
- Person name (collector, donor, seller)
- Institution name (transferring institution)
- Location (field collection locality)
- Dealer or auction house
acquisition_agent:
range: string
description: >-
Agent who performed the acquisition (collector name, curator, institution).
For biological specimens, maps to dwc:recordedBy.
acquisition_location:
range: string
description: >-
Location where acquisition occurred (field collection site, auction house location).
For biological specimens, can capture field locality.
acquisition_reference:
range: string
description: >-
Reference number or identifier for the acquisition (accession number, lot number).
acquisition_notes:
range: string
description: >-
Additional notes about the acquisition event.
acquisition_date_text:
range: string
description: >-
Original date text as recorded (e.g., "1750s", "pre-1662", "circa 1900").
For backward compatibility with string-based collection_date.
The structured date should be in temporal_extent.
