A portal interface to Grid workflow technology

Workflow technology previously developed by the Grid project has been used to automate a number of complex bioinformatics analyses, allowing much larger volumes of data to be produced than would be possible if these analyses were to be performed manually. Grid workflows can be constructed using the Taverna workbench, and the analysis specified by such a workflow can be performed throught the use of a workflow enactment engine. This paper describes the design and implementation of a simple user-interface which aims to support the use of workflow technology by providing web-based access to workflow and results management facilities. This interface has been constructed using the Gridsphere portal framework, and makes use of storage facilities provided by the Grid Information Repository.
