Interface Derivation

All Known Implementing Classes:

RuleDerivation

public interface Derivation

Derivation records are used to determine how an inferred triple was derived from a set of source triples and a reasoner. SubClasses provide more specific information.

A future option might be to generate an RDF description of the derivation trace.
