public class RDFSForwardRuleReasoner
extends GenericRuleReasoner

An pure forward chaining implementation of the RDFS closure rules based upon the basic forward rule interpreter. The normal mixed forward/backward implementation is generally preferred but this has two possible uses. First, it is a test and demonstration of the forward chainer. Second, if you want all the RDFS entailments for an entire dataset the forward chainer will be more efficient. * @author Dave Reynolds * @version $Revision: 1.2 $ on $Date: 2003/08/27 13:11:15 $
