Choreographies enable the coordination of interactions between business partners. Established modeling languages such as BPMN focus on a visual notation that may facilitate design but lacks formal semantics. Moreover, such notations encourage the explicit ordering of interactions, which often results in over-constrained models. In contrast, information protocols provide a precise and flexible operational model for interaction. This paper contributes a tool-supported, semi-automated mapping from object-aware BPMN choreography diagrams to information protocols. Our approach enables business experts to tailor the flexibility of the resulting protocols to their requirements.
