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.
