Abstract. By now, the mapping from BPMN to BPEL has been implemented in numerous tools, greatly assisting the business architect in the creation of BPEL processes. However, most of these tools are tailored especially for this transformation, neglecting the original purpose of BPMN: Providing a language independent process model. To address this shortcoming, a pure BPMN editor is needed, being dynamically extensible with several export features and added editing functionality. In this paper, we present a tool that follows this approach, not only providing a compelling transformation to BPEL but at the same time being extensible to other languages. Key words: BPMN, Process Design Tools, Model Driven Development, Transformations, Multi-agent Systems
