I've been reading about BPMN and other business process modeling language and for what I could understand (please correct me if I'm wrong) the main goal of BPMN is the graphical representation. Furthermore, BPMN doesn't have a standard mapping for BPEL.
My question is…if the model design isn't described using Activity but some other external tool and I want to use Activity's Workflow engine to execute it, how can I describe it so Activity understands?
What I mean is, if I just want to input my workflow to be executed how should I do it with Activity? Should I use BPEL? Or does BPMN have an execution modeling implementation?
Thanks in advance
