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 hand...

The Business Process Modelling Notation (BPMN) is a graph-oriented language in which control and action nodes can be connected almost arbitrarily. It is primarily targeted at domain analysts and is supported by many modelling tools, but in its current form, it lacks the semantic precision required to capture fully executable business processes. The Business Process Execution Language for Web Se...

The Business Process Execution Language for Web Services (BPEL) has emerged as the de-facto standard for implementing processes. Although intended as a language for connecting web services, its application is not limited to cross-organizational processes. It is expected that in the near future a wide variety of process-aware information systems will be realized using BPEL. While being a powerfu...

Web service technologies are best exploited by composing services, and BPEL (Web Services Business Process Execution Language) is adopted industrial-wide as the de facto service composition standard. However, a BPEL composite service is typically treated as a fully automated service flow that orchestrates multiple web services and involves no user interactions – a desirable feature for service ...

BPEL (Business Process Execution Language) as a de-facto standard for web service orchestration has drawn particularly attention from researchers and industries. BPEL is a semi-formal flow language with complex features such as concurrency and hierarchy. To test a model thoroughly, we need to cover different execution scenarios. As is well known, it is tedious, time-consuming, and error prone t...

Adding Adaptation to the BPELgold Model Chain Since adaptation of the interacting services is not addressed in the original model chain for BPELgold, we have extended the tool chain by adding minimal adaptors (gray box) which can be automatica...

Aside from business processes, the service-oriented approach— currently realized with Web services and BPEL—should be utilizable for data-intensive applications as well. Fundamentally, data-intensive applications are characterized by (i) a sequence of functional operations processing large amounts of data and (ii) the delivery and transformation of huge data sets between those functional activi...

The general concept of inter-workflow system communications has been proposed by the WfMC in 1995. However, there has been little study or use case on general inter-workflow system communications, except for business massage exchange-based protocols. Since BPEL allows a local system to invoke remote BPEL Processes via Web Service interface, this can be used as a mechanism for inter-workflow com...

The paper contributes to modeling an orchestrated complex Web Service (BPEL) with Colored Petri Nets (CPNs) for diagnosis. In the CPNs model, colored tokens are used to represent the faults in a BPEL process. A uniform fault model is introduced to represent both the faulty input data and external faulty Web services called by the BPEL activities. We use three I/O data dependency relations for e...
