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.
