In Fig.1 the hierarchic taxonomy of the resulting combined Ontology is represented in a tree-like form. Relations between the classes, subclasses and individuals are represented in Fig.2. Latter shows a high degree of interdependence between these classes and individuals, while the connections mostly originate from the “design classes” of each individual system as well as the class of the Renewable Energy Configuration. The most linked class is the parent class “EnergySupplyOfCity”. The lines represent the defined object restrictions (s. Fig.3)

Besides a visual evaluation of the ontologic model, a reasoner can be used in order to understand and review the defined relations between the concepts. By starting the reasoner Pellet, relations between the individuals and classes based on the property restrictions are inferred and shown as object property assertions in the “individual by class” tab. Fig. 4 shows some results of the reasoning process for different individuals and the inferred relations are correct for every individual.
