A Study on Modeling of Lightweight Scientific Workflow Systems Using XML Schema

摘要

Scientific workflow systems are typically describe coordinations involved in data processing via a workflow definition language. However, current specific workflow definition languages, even adopted by current mature scientific workflow systems, are too complex and enormous for non-professionals. In this paper, we mainly discuss how to design a workflow definition language using XML schema to suit a lightweight workflow system in a specific domain such as astronomy and astroinformatics. The prototype system shows that a simple but intuitive workflow definition language can simplify the modeling procedure and make end users easier and more accurate to implement their research tasks in e-Science activities.
