The wide adoption of Service Oriented Architecture by the Grid community has made available several software tools that allow exposing hardware resources and scientific data to remote peers by means of well standardized protocols. Hence the necessity for scientists to easily design a simulation that leverages distributed applications. In this paper, we present the implementation details of A-WARE, a workflow framework that adopts recognised standards, especially by the enterprise community, like BPEL. In this way our product can boast a higher level of interoperability with other similar systems. The workflow graphical notation is also based on a standard: BPMN. BPMN provides a unique, standardized and comprehensive modeling format understandable by both business people (involved in the area of business process management) and IT people, resulting also portable across different departments or companies.
