Abstract

Due to massive effort in tailoring workflow management systems towards the bioinformatics domain and the development of thoroughly specific systems in the last years, several frameworks that support service orchestration in bioinformatics are available today. They provide a wide range of different features, adding convenience for the user in different ways. This chapter discusses the relation of Bio-jETI to other approaches to bioinformatics workflow management. Therefore, Section 8 reviews a number of different bioinformatics workflow systems and compares them to Bio-jETI. Then, Section 8.2 takes a closer look at the substantial differences between the capabilities of controlflow and data-flow modeling: The nature of the data flow and control flow specifications is essential for the semantic interpretation of a workflow model, while other features are usually less inherent in the systems. The study is carried out by means of a detailed comparison of Bio-jETI and Taverna, two systems for bioinformatics workflow management that look very similar at the first glance, but are in fact very different precisely because they follow different paradigms for control-flow and data-flow modeling.
