Activity-Centric and Artifact-Centric Process Model Roundtrip

Currently, two major process modeling paradigms exist: activitycentric and artifact-centric. They focus on different first class modeling constructs and therefore, they are eligible for different scenarios. Nevertheless, both paradigms compete for users raising the own capabilities over the other’s ones neglecting that both paradigms are compatible to each other such that one can transform one into the other one. In this paper, we provide a set of algorithms to allow these transformations as roundtrip, i.e., from an artifact-centric process model to an activity-centric one and back and vice versa. To this end, we utilize a synchronized object life cycle as mediator between both paradigms. We show applicability of our algorithms by discussing them in combination with an example.
