Scientific Workflows: Eternal Components, Changing Interfaces, Varying Compositions

摘要

We describe how scientific application domains are characterized by the long-term availability of the basic computational components, and how software systems for managing the actual scientific workflows must deal with changing service interfaces and varying service compositions. In this light, we explain how rigorous technical and semantic abstraction, which is key to dealing with huge and heterogeneous application domains in an "extreme model driven design" framework like the jABC, supports the management of workflow evolution. We illustrate the different aspects by means of examples and experiences from the application of the framework in different scientific application domains.
