This paper satisfies the first variation of the use case. This bridge allows the reproduction of the BPEL models from the BPMN models given as example for this variation. To take in charge the other variations, an idea to develop could be the use of intermediate representations and transformations between BPMN and BPEL. This method could ease the development of the transformations by allowing a more direct mapping between the representations and an easiest definition of the transformation rules. The current solution already shows that chaining transformations enables to solve different problems independently.
