RDF Representation in Jena Ai

RDF N-triple can represent with RDF model. RDF is best thought of in the form of node and arc diagrams. A simple vcard might look like this in RDF:


Ellipse represents the Resources of the concept.
Arc represents the Properties of the concept.
Rectangle represents the literal/Resources of the concept.
