BPELscript: A Simplified Script Syntax for WS-BPEL 2.0

Business processes are usually modeled using graphical notations such as BPMN. As a first step towards execution as workflow, a business process is transformed to an abstract WS-BPEL process. Technical details required for execution are added by an IT expert. While IT experts expect Java-like syntax for programs, WS-BPEL requires processes to be expressed in XML. This paper introduces BPELscript as a new syntax for WS-BPEL aiming to reduce the barrier for IT experts to use WS-BPEL by providing a JavaScript-inspired syntax.
