BPEL-TC: Orchestration of Temporally Customized Web Services

Abstract

WS-BPEL is way to orchestrate web services. It defines business processes that interact with external entities through web service operations using WSDL. The existing system defines service flow using Web Services based on WSDL. We have proposed BPEL-TC, an extension to existing WS-BPEL which uses temporally customized Web Services as a model for process decomposition and assembly. WSDL-TC handles both backward compatible and incompatible changes and also maintains various versions of the artifacts that results due to changes over time and customizations desired by the users. A formal representation of BPEL-TC is also presented using Kleene Algebra with Test (KAT).
