The conceptual architecture of biowep. The architecture of biowep includes three components. The Workflow Manager (WM) for the creation of predefined workflows by using Taverna or BioWMS, and their annotation that is done by using a classification of bioinformatics tasks (ontology). The User Interface (UI) supports end users authentication and profiling and selection and enactment of workflows. This can be carried out by searching workflows annotations. The Workflow Executor (WE) enacts workflows by using FreFluo or by submitting them to BioAgent/Hermes.
