  • ocel:eid - Unique event identifier (UUIDv7)
  • ocel:activity - Canonical activity name (resource.action or ash_r2rml.reactor.step)
  • ocel:timestamp - ISO 8601 UTC timestamp
  • ocel:omap - List of polymorphic object instance identifiers participating in the event
  • ocel:vmap - Map of event attributes enriched with genuine Ash and semantic introspection
