What is the relationship between BPMN and WS-BPEL 2.0?
WS-BPEL is an OASIS standard for a service orchestration language. BPMN is an OMG standard for visual representation of a business process. While a BPEL process can be represented using BPMN, some BPMN models cannot be represented using BPEL. At the time this FAQ was prepared there were no mappings from BPMN to WS-BPEL 2.0.
