Abstract: This paper describes the use of the Business Process Execution Language for Web Services (BPEL4WS/BPEL) for managing scientific workflows. This work is result of our attempt to adopt Service Oriented Architecture in order to perform Web services – based simulation of metal vapor lasers. Scientific workflows can be more demanding in their requirements than business processes. In the context of addressing these requirements, the features of the BPEL4WS specification are discussed, which is widely regarded as the de-facto standard for orchestrating Web services for business workflows. A typical use case of calculation the electric field potential and intensity distributions is discussed as an example of building a BPEL process to perform distributed simulation constructed by loosely-coupled services. Keywords: BPEL, scientific workflows, Web services, SOA. ACM Classification Keywords: D.2.12 Interoperability - Distributed objects Link: USING THE BUSINESS PROCESS EXECUTION LANGUAGE FOR MANAGING SCIENTIFIC PROCESSES Anna Malinova, Snezhana Gocheva-Ilieva?
