Orchestra Designer: an open-source tool for scientific workflow modeling

Scientific workflow has become an important tool used by scientists to operate distributed resources in current scientific research. However, the gap between scientific domain and workflow specification has increased the difficulty of adopting scientific workflow. Further, the lack of collaborative mechanism has gradually become a major obstacle for scientists to share scientific workflow. In this paper, we introduced an open-source tool for scientific workflow modeling, called Orchestra Designer. It solves above problems by isolating domain tasks from workflow specification and providing a service-oriented collaboration bus. Meanwhile, Orchestra Designer supports the design of cross domains scientific workflows.
