<p><b>Figure 5.2</b> illustrates a part of Wine Ontology described in RDFS 
rather than OWL. You may make this RDF graph in a usual manner of CLOS object 
definition, namely in order from abstract classes to special classes and from 
classes to instances. However, SWCLOS allows you to define any object in any 
order with the premise of monotonicity principle. SWCLOS ensures the final 
result shown in Figure 5.
