摘要: Web services composition is an emerging paradigm for enabling application integration within and across organizational boundaries. In this context, we propose approach based on Symbolic Observation Graphs (SOG) allowing to decide whether two (or more) web can cooperate safely. The compatibility between defined by the well known soundness property open workflow nets. This guarantees absence of anomalies (e.g. deadlock) that appear after composition. We abstract concrete behavior a service using SOG show how as check be achieved through their abstractions (i.e. SOGs). allows respect privacy since SOGs are collaborative activities only hide internal structure corresponding service.
