Metamodel user guide
BPMN provides modelers with the capability of showing additional information about a Process that is not directly related to the Sequence Flow or Message Flow of the Process.
At this point, BPMN provides three (3) standard Artifacts: Associations, Groups, and Text Annotations

Association | Description |
---|---|
Process : BpmnProcess [0..1] | |
SubProcess : BpmnSubProcess [0..1] | |
Collaboration : BpmnCollaboration [0..1] |
An Artifact MUST NOT be a target for Sequence Flow.
An Artifact MUST NOT be a source for Sequence Flow.
