Classical notations for service collaborations focus either on the control ﬂow of participating services (interacting models) or the order in which messages are exchanged (interaction models). None of these approaches emphasizes the evolution of data involved in the collaboration. In contrast, artifact-centric models pursue the converse strategy and begin with a speciﬁcation of data objects. This paper extends existing concepts for artifact-centric business process models with the concepts of agents and locations. By making explicit who is accessing an artifact and where the artifact is located, we are able to automatically generate an interaction model that can serve as a contract between the agents and by construction makes sure that speciﬁed global goal states on the involved artifacts are reached.
