EPC to BPMN transformation rules

The following describes the rules according to which a business process model of type EPC is transformed to a model of type BPMN collaboration diagram (BPMN 2.0).

Assigned objects such as service types, and organizational elements that do not represent any control flow elements create assignments in turn.
