When processing an OWL ontology file we note the following:

		IGPO classClass = m_om.getGPO(OWL.CLASS);
		System.out.println("ClassClass: " + classClass.pp());
		System.out.println("RDFS.SUBCLASSOF: " + RDFS.SUBCLASSOF);
		
		Iterator owlClasses = classClass.getLinksIn(RDF.TYPE).iterator();

The classes that do not have a value for RDF.SUBCLASSOF are the base classes.

To determine the class properties we need to retrieve the ObjectProperty(s) and DatatypeProperty(s)

The ObjectProperty expects the rdfs:domain to reference an Class object.

A DatatypeProperty requires the rdfs:domain to reference a datatype such as XMLSchema#string.


 
    
    
    
  
  
    
    
    
  

Therefore we can process the properties of a class with

class.getLinksIn(RDFS.DOMAIN);

Iterating the solution and checking for OWL.DATATYPEPROPERTY vs OWL.OBJECTPROPERTY
will determine the attributes and associations for a class.

A real issue again is whether we can cache the LinkSets.  I don't really see how
this can work. I guess it may be possible to cache LinkSets at the skin level.

Alternatively,
