Choreography Conformance Checking: An Approach based on BPEL and Petri Nets

Abstract

Recently, languages such as BPEL and WS-CDL have been proposed to describe interactions between services and their behavioral dependencies. The emergence of these languages heralds an era where richer service descriptions, going beyond WSDL-like interfaces, will be available. However, what can these richer service descriptions serve for? This talk discussed the use of event logs of web services and behavioral service descriptions as input for process mining and conformance checking. Conformance checking is the act of verifying whether or not one or more parties stick to an agreed-upon behavior, by observing their actual behavior as recorded in message logs. This talk shows that it is possible to translate BPEL business abstract processes to Petri nets and to relate SOAP messages to transitions in the Petri net. The approach has been implemented in the ProM framework.
