The answer is that the notation for describing individuals is a matter for RDF, not OWL. You can write <Description rdf:about="URL_of_individual"> <rdf:type rdf:resource="&myont;University"/> </Description> which can be abbreviated <University rdf:about="URL_of_individual"/> > Besides, i would also want to ask what is the role of the individual > which is written inside the ontology? An individual who appears in an ontology must play some distinct role that most individuals don't. In a monotheistic ontology, #God might get mentioned. In a polytheistic ontology, there might be no individuals mentioned. > why dont all individual to be written inside the html page? I don't know what that means. > Moreover, what is the function of enumeration? To define a finite, smallish, class. > if we create an individual of a classDescriptions, then is it necessary to put it into the enumeration? if it is, why? Which enumeration? -- -- Drew McDermott Yale University CS Dept.
