org.apache.stanbol.entityhub.model.sesame.RdfRepresentation
A {@link Representation} implementation backed by a Sesame {@link Model} @author Rupert Westenthaler
org.restlet.ext.rdf.RdfRepresentation
Generic RDF representation. Provides support for the Resource Description Framework (RDF) Semantic Web standard. It supports major RDF serialization formats (n3, Turtle, N-Triples and RDF/XML) and is able to both serialize and deserialize a {@link Graph}. @author Jerome Louvel
