This paper proposes an approach to generic object concepts for problem solving method ontologies and knowledgebased systems. By using placeholders, whose main purpose is to define characteristics of the objects upon which the method acts without specifying a domain, method ontologies can become more reusable. The re-usability stems from the ability to merge such method ontologies more easily with fitting domains. The generic object concepts in the method are proposed to be used as a bridge to the domain ontology. The paper provides a comparison to similar methods in related studies.
