Abstract :
The authors present an approach for compiling "scientist-friendly" abstract workflow specifications into real-world executable workflows of Web service invocations, using a set of abstract-as-view definitions from a repository of abstract tasks. There have been a number of proposals and systems for scientific workflow management. However, our approach features unique aspects, in particular: the separation of abstract and concrete executable workflows; and the use of database mediation techniques to automatically translate AWFs into EWFs.
