A Connection of Task-centric with Artefact-centric Models through Semantic Task Specification and its Use for Formal Verification

Abstract

Task- and artefact-centric business process models (BPMs) are mostly used in isolation. This entails, e.g., problems with formal and automated verification of BPMs through model checking. We address this gap through semantic task specification, which is transferred from more widely known semantic service specification. In summary, we present a new and systematic approach for connecting a task-centric BPM (in BPMN) with a model of an artefact-centric object life cycle through semantic task specification. As a consequence, we achieve a seamless approach for formal and automated verification of BPMs using model checking
