Abstract

We present open questions regarding event-related aspects in the Business Process Model and Notation (BPMN) 2.0 standard. Drawing on our experience in formalising the semantics of BPMN, we discuss triggers and event definitions, the question whether receive tasks may start event sub-processes, implicit" start/end events, and compensation event sub-processes. For the time being, these questions remain unanswered for us, and we hope to trigger a clarifying discussion with our paper.
