Examples of org.ontoware.rdf2go.ModelFactory

org.ontoware.rdf2go.ModelFactory
RDF2Go adapters have to implement this interface to be able to create Models and ModelSets. Property keys are defined in this interface (Reasoning, Storage). @author voelkel

    // getting a ModelFactory, declaring a model
