A new language to define bioinformatics workflows using Web services

Workflow systems provide a perfect fit for the explorative research of bioinformaticians. These systems can help bioinformaticians to design and run their experiments and to automatically capture and store the data generated at runtime. In this paper we present a new language (workflow representation) that enables the design of high-level workflow models. Such a workflow system will be much easier in use and will better suit the bioinformaticians needs. In the paper, we describe the overall framework of our approach and provide a detailed description of the techniques proposed. Finally, the usefulness of our approach is demonstrated through a bioinformatics case study.
