A BPEL engine and editor for the .NET framework

Abstract

In today's world of extreme competition, information exchange and efficient communication is the need of the day. This need for information exchange brings in another need, that which makes information selectively visible, and its visibility to be changed on the fly. Web Services are a new breed of web application and play a central role in the WWW, providing the above-mentioned requirements. The composition of these services enables application integration within and across organizational boundaries. The Business Process Execution Language (BPEL) is intended to enable portable business process definitions for WSDL based services. In this paper we describe the work done on a BPEL execution engine and editor developed for the .NET framework. We also describe how a graphical representation based on UML activity diagrams was used to visualise service compositions and how this can be adopted as the underlying model for Semantic Web service descriptions such as OWL-S.
