The paper presents and elaborates on the idea of automatic acquisition of knowledge about domain structure from ontologies into an object-oriented software development process. The information required to be included in the domain model produced during the development process is identified. The existence of the knowledge in ontologies is investigated. Requirements for ontology description languages are formulated followed by brief evaluation of existing languages against these requirements. A schema for domain knowledge acquisition is outlined. A realization of the schema is sketched in the paper while the implementation details can be found in the technical report.
