I agree with Danushka. When it comes to workflow engines I think it is better to study general concepts of workflow engines first and then study the prominent *Scientific* work flow engines (Some of the challenges are different from business workflow engines). Each prominent workflow engine comprise of several unique features and concepts while major abstraction is workflows. I would like to add Apache OODT into list of prominent workflow engines (Workflow processing components are key part of Apache OODT and used in several NASA missions and other research) . I have already some work on these items and would like to contribute them into wiki.
