BPMN is important standard which is widespread applied in the enterprise process described by the standard diagram, It is instituted by the international standardorganization------BPMI (Business Process Management Initiative) . BPMN is a set ofnotation, its goal is to let the enterprise process model easily to exchange through the standardized notation.BPEL, is one kind of language which describes the enterprise interior process by XML, enables the business process built-up the different product to communicate inter platform like the network service. BPEL originates from Microsoft and IBM's process standard language such as XLANG and WSFL, and it is admitted by the OASIS.Firstly, this paper introduces the relative technologies of BPMN and BPEL, and then analyses the existing mapping from BPMN to BPEL. Basing on this, this paper points out that the core problem of mapping from BPMN to BPEL is that process direction in BPMN can flow arbitrarily. However, process direction except loop in BPEL is always forward. But BPEL has some special rules to loop process, that is to say, loop process just has only one entrance and one exit. Although process direction in BPMN can flow arbitrarily, if loop process in BPMN can be wiped off, process direction except loop in BPMN is always forward. So, this paper centralize the problem of mapping from BPMN to BPEL as how to exchange from loop process in BPMN to that in BPEL.In addition, this paper also defines the concept of overlap loop, and proposes the algorism of searching overlap loops and the algorism of wiping off overlap loops. Finally, it proposes the mapping from BPMN to BPEL.
