Examples of ModelGraph

org.apache.clerezza.rdf.jena.tdb.internals.ModelGraph
Represents the Jena {@link Model} and the Clerezza {@link Graph} or{@link MGraph}. It also provide access to the {@link JenaGraphAdaptor}so that this component can add parsed data to {@link Graph}s created by calls to {@link SingleTdbDatasetTcProvider#createGraph(UriRef,TripleCollection)}. @author Rupert Westenthaler
org.apache.oodt.cas.workflow.gui.model.ModelGraph
The graph to display per workflow in the Workflow Editor GUI. @author bfoster @author mattmann
org.openengsb.core.ekb.api.ModelGraph
The model graph is used as base for the finding of transformation descriptions and is able to perform graph based algorithm on the transformation graph.
