John Conery Department of Computer and Information Science University of Oregon Rule-Based Workflow Most workflow management systems take a process-oriented approach to describing workflows, where the focus is on applications and how they are interconnected. This talk presents an alternative, data-centric approach, where the emphasis is on work products. A workflow description is a set of rules, where each rule describes the data produced by a workflow step, the data the step depends on, and the processes used to produce the data. A prototype workflow enactor named PIP uses this rule-based model to manage several bioinformatics projects, including the construction of a tRNA datamart and projects related to the evolution of duplicate genes. Advantages of the rule-based approach are modularity and reusability: steps in a PIP workflow can be described as objects, and new steps can inherit many of the attributes of previously developed steps. Bio John Conery is a Professor of Computer and Information Science at the University of Oregon, where he has been a faculty member since earning his PhD at UC Irvine in 1983. His research interests include parallel processing, computational science, and bioinformatics. _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
