Over the past few years, workflow patterns have become a touchstone of workflow standards and products. The Workflow Patterns initiative is a joint effort of Eindhoven University of Technology (led by Professor Wil van der Aalst) and Queensland University of Technology (led by Professor Arthur ter Hofstede) which started in 1999. The aim of this initiative is to provide a conceptual basis for process technology. In particular, the research provides a thorough examination of the various perspectives (control flow, data, resource, and exception handling) that need to be supported by a workflow language or a business process modelling language. This session presents how these workflow patterns, as well as dataflow patterns, can be modeled using BPMN 2.0. Also discussed will be the advantages of using BPMN 2.0 when modeling these patterns. Further, we will focus on specific constructs in BPMN 2.0 that let the users extend the workflow patterns if required. Our initial intent is to target the various control flow patterns.
