Towards Resource-Oriented BPEL
نویسنده
چکیده
Service orientation is the de-facto architectural style, today. But, what actually is a service and how should service boundaries be chosen? Resource orientation, once seen as a ”light-weight” approach to Web services, is reshaping itself as a modeling strategy to service orientation. Along comes the realization that resources are in-fact complex state machines. Currently, there is no accepted standard for modeling the internal state of resources. In this paper, BPEL is proposed as a modeling language for resources and necessary extensions to BPEL are outlined.

RESTful Web services are thus hard...

In this paper we present BPEL which decouples process logic from interface definitions. By extending BPEL 2.0 with a WSDL-less interaction model, BPEL 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 o...
