MOKA KA application is elaborated in Protégé-OWL system. It is used for obtaining knowledge in designing process, for elaborating KBE (Knowledge Based Engineering) application and for creation of knowledge base for this system. It uses MOKA methodology and in particular informal model from this methodology and the concept of ICARE forms (Illustration, Constraint, Activity, Rule, Entity). Knowledge referring to the structure of a designed product and its designing process is collected by means of forms. Additionally for the purpose of correct construction of informal model, a formal model from MOKA has been partly used. The ontology suggested in application although it is based on MOKA methodology it cannot be treated as true transfer of ontology from MOKA due to the fact that the ontology had to be adapted for the requirements of representation of Protégé-OWL system. For the usage of MOKA KA application it is necessary to have Protégé-OWL platform installed.
Knowledge acquisition can be carried by structuralised interview by an engineer who has a command of MOKA methodology or independently by a designer, however, it is necessary for a designer to get to know with informal knowledge model from MOKA methodology.
