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)'

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.
comments:
- Created per slot_fixes.yaml revision for collection_date migration
- Replaces simple collection_date string with structured acquisition event
- "RULE 53: Part of collection_date \u2192 was_acquired_through + Acquisition migration"
