Enterprises today face an increasing need to easily access and process knowledge they produce as well as automate their business processes. This need may be fulfilled by taking advantage of the Semantic Web and Semantic Web services technologies and implementing the concept of Semantic Business Process Management. In order to fulfil this vision, an enterprise and the specified part of the knowledgefrom the enterprise’s environment needs to be properly described. The main goal of this paper is to present Business Roles Ontology (BRO) and Business Functions Ontology (BFO) which are to provide description of business functions and corresponding business roles. Both ontologies may be used within automated business process management lifecycle and are the result of our research work.
