OBSERVED_COMPACTION
OBSERVED_COMPACTION edge/relationship definition.
Description
Connects an ( :Activity ) node to a DEPOSIT ( :Place:Context ) node to record that this Activity observed/recorded the Deposit's compaction.
Analogy
Join row(s) or table(s) linking Activities to the observation of a Context's compaction.
CIDOC-CRM Mapping
MAYBE include a short summmary here, but leave the details for the designated CIDOC-CRM section.
Relevant Nodes, Directions, and Cardinality
[ :Activity:FieldworkProcess ] ——[ :OBSERVED_COMPACTION ]——> @[0..*] [ :Place:Context ] ⟵ @[0..*]
- Each FieldworkProcess may observe the compaction of zero or many Deposit Contexts.
- Each Context may have multiple compaction observations by different FieldworkProcess activities.

POSSIBLE: System/Audit Properties
Need to decide if we should include the full (or a partial) audit trail for edge/relationships. I'm leaning toward YES.(these are not required/enforced by Neo4j but are populated via the UJAP Database web application; these could also be handled—perhaps more simply—by edge/relationship to AuditEvent nodes)
