- Removed compliance_status slot and replaced it with has_or_had_status. - Updated has_or_had_status to use ComplianceStatus for structured representation. - Adjusted examples to reflect new structure for compliance status. - Updated documentation to indicate migration and provide details on the ComplianceStatus class.

|
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)
