This paper investigates the use of the Business Process Execution Language for Web services (BPEL4WS/ BPEL) for managing scientific workflows. The complexity, unpredictability and inter-dependency of the components in a scientific workflow often demand great flexibility in a workflow-language in order to support; exception handling, recovery from uncertain situations, user interactions to facilitate interactive steering and monitoring, dynamism to adapt to the changing environment, compensation handling to reverse the effects of previous activities that have been abandoned, and flexibility to support dynamic selection of services at runtime and to support changing data requirements.
