Tracking Causal Dependencies in Web Services Orchestrations Defined in ORC

This article shows how the operational semantics of a language like ORC can be instrumented so that the execution of a program produces information on the causal dependencies between events. The concurrent semantics we obtain is based on asymmetric labeled event structures. The approach is illustrated using a Web service orchestration instance and the detection of race conditions.Comment: NETYS - 3rd International Conference on NETwork sYStems, May 2015, Agadir, Morocco. 2015, Proceedings of the third international conference on network system
