Abstract:
Existing knowledge based Grid workflow languages and composition tools require sophisticated expertise of domain scientists. This paper presents a novel domain oriented approach which features separations of concerns between data meaning and data representation and between activity function and activity type. These separations are implemented as part of AGWL which supports the development of Grid workflows at a high level (semantic) of abstraction. The corresponding workflow composition tool simplifies Grid workflow composition by (i) enabling users to compose Grid workflows at the level of data meaning and activity function that shields the complexity of the Grid, any specific implementation technology and any specific data representation, (ii) semi-automatic data flow composition, and (iii) automatic data conversions. We have implemented our approach as part of ASKALON. We demonstrate the effectiveness of our approach by applying it to a real world meteorology workflow application and report some preliminary results.
