A process ontology to represent semantics of different process and choreography meta-models

Currently external business process descriptions (choreographies) are discon- nected from the internal processes (workflows), leading to several problems. Directly map- ping internal to external processes requires a quadratic amount of mappings; an intermediate ontology reduces the amount of necessary mappings but is not trivial to construct, due to the variety in workflow metamodels. In this paper we introduce our multi metamodel process ontology (m3po), which is based on various existing reference models and languages from the workflow and choreography domain. This ontology allows the extraction of arbitrary choreography interface descriptions from arbitrary internal workflow models. We also report on an initial validation: we translate an IBM Websphere MQ Workflow model into the m3po ontology and then extract an Abstract BPEL model from the ontology.
