In this paper we present BPELlight which decouples process logic from interface definitions. By extending BPEL 2.0 with a WSDL-less interaction model, BPELlight allows to specify process models independent of Web service technology. Since its interaction model is based on plain message exchange, it is completely independent of any interface description language. This fosters flexibility and reusability of process models and enables modelling platform and component model independent business processes. The presented approach takes a significant step towards narrowing down the gap between business level and IT level by facilitating a more business-oriented modelling of executable processes.
