Abstract. Business process models usually capture data exchanged between tasks in terms of objects. These objects are commonly standardized using reference data models that prescribe, among other things, allowed object states. Allowed state transitions can be modeled as object life cycles that require compliance of business processes. In this paper, we first establish a notion of compliance of a business process model with an object life cycle. We then propose a technique for generating a compliant business process model from a set of given reference object life cycles.
