Business Processes Meet Spatial Concerns: The sBPMN Verification Framework

BPMN is the standard for business process modeling. It includes a rich set of constructs for control-flow, inter-process communication, and time-related concerns. However, spatial concerns are left apart while being essential to several application domains. We propose a comprehensive extension of BPMN to deal with this. Our proposal includes an integrated notation, a first-order logic semantics of the extension, and tool-supported verification means through the implementation of the semantics in TLA\(^+\). Our tool support and our model database are open source and freely available online.
