The WS-BPEL language has recently become a de facto standard for modeling Web-based business processes. One of its essential features is the fully programmable compensation mechanism. To understand it better, many recent works have mainly focused on formal semantic models for WS-BPEL. In this paper, the authors make one step forward by investigating the verification problem for business processes written in BPEL-like languages. They propose a set of proof rules in Hoare-logic style as an axiomatic verification system for a BPEL-like core language containing key features such as data states, fault and compensation handling.
