    description: |
      Ongoing collection management activities performed to preserve heritage for access.

      **CIDOC-CRM Definition**:

      E87_Curation_Activity comprises "the activities that result in the continuity of
      management and the preservation and evolution of instances of E78 Curated Holding."

      **KEY DISTINCTION**:

      | Concept | Class | Duration | Example |
      |---------|-------|----------|---------|
      | **Curation Activity** | CurationActivity | Ongoing/recurring | Annual inventory |
      | Exhibition | Exhibition | Time-bounded | "Van Gogh Retrospective" |
      | Conservation treatment | ConservationRecord | Discrete action | Frame repair |
      | Provenance event | ProvenanceEvent | Point-in-time | Sale at auction |

      **RELATIONSHIP TO COLLECTION**:

      ```
      Collection (rico:RecordSet)
          │
          ├── items → ExhibitedObject[]
          │
          └── curation_activities → CurationActivity[] (THIS CLASS)
                  │
                  ├── activity_type: CurationActivityTypeEnum
                  ├── curated_holding: Collection (back-reference)
                  ├── objects_affected: ExhibitedObject[]
                  ├── responsible_actor: PersonObservation
                  └── activity_timespan: TimeSpan
      ```

      **SPECTRUM ALIGNMENT**:

      Maps to SPECTRUM (UK Collections Management Standard) primary procedures:

      | SPECTRUM Procedure | CurationActivityTypeEnum |
      |--------------------|--------------------------|
      | Object Entry | ACCESSIONING |
      | Acquisition | ACQUISITION_RESEARCH |
      | Inventory Control | INVENTORY |
      | Cataloguing | CATALOGING |
      | Object Storage | REHOUSING, STORAGE_REORGANIZATION |
      | Location and Movement | RELOCATION |
      | Condition Checking | CONDITION_SURVEY |
      | Collections Care | PREVENTIVE_CONSERVATION |
      | Deaccession and Disposal | DEACCESSIONING |
      | Loans Out/In | OUTGOING_LOAN_MANAGEMENT, INCOMING_LOAN_MANAGEMENT |
      | Valuation | VALUATION |
      | Audit | AUDIT |

      **ACTIVITY CATEGORIES**:

      1. **Acquisition/Disposal**: Accessioning, deaccessioning, collection review
      2. **Documentation**: Cataloging, inventory, provenance research, rights research
      3. **Physical Management**: Rehousing, relocation, storage reorganization
      4. **Preservation**: Condition surveys, preventive conservation, disaster planning
      5. **Access**: Digitization, photography, interpretation, online publication
      6. **Loans**: Outgoing and incoming loan management
      7. **Administrative**: Collection development, registration, valuation, audit
      8. **Integration**: Database migration, vocabulary alignment, linked data

      **PROVENANCE TRACKING (PROV-O)**:

      CurationActivity generates provenance information:
      - `prov:Activity` - The curation activity itself
      - `prov:wasAssociatedWith` - Responsible actor (staff, contractor)
      - `prov:used` - Objects/collections processed
      - `prov:generated` - Documentation, reports, digital surrogates
      - `prov:atTime` - Activity timespan

      **DELIVERABLES**:

      Activities typically produce documentation:
      - Accession records (ACCESSIONING)
      - Catalog records (CATALOGING)
      - Condition reports (CONDITION_SURVEY)
      - Finding aids (CATALOGING for archives)
      - Digital surrogates (DIGITIZATION)
      - Valuation reports (VALUATION)
      - Audit reports (AUDIT)
