Nowadays, linkage of BPMN 2.0 business process models with ontologies to achieve consistency and semantic compatibility is still a challenge. This paper addresses a question of finding BPMN 2.0 meta-model compatible upper ontology for the analysis of the completeness of BPMN 2.0 model. Upper ontologies are meta-structures for domain ontologies and based on the correspondence between BPMN 2.0 meta-model and upper ontology a link between BPMN 2.0 models and domain ontology can be provided. A comparison of 5 existing upper ontologies showed that the Bunge-Wand-Weber ontology is the most compatible with the BPMN 2.0 meta-model.
