Enhancing BPMN 2.0 support for service interaction patterns

Choreography modeling languages have emerged in the past years as a mean for capturing and managing collaborative processes. The advancement of such languages let to the definition of the service interaction patterns, a pattern-based framework for the benchmarking of choreography languages against abstracted forms of representative scenarios. Service interaction patterns have been used to analyze the capabilities of different languages. Since its introduction, no benchmark based on this framework has been performed on the Business Process Model and Notation (BPMN) version 2.0. In this paper, we present an assessment of BPMN 2.0 support for service interaction patterns. We evidence the issues that limit the set of supported patterns, and propose enhancements to overcome them.
