     <p>N-quads statments are a sequence of RDF terms representing the subject, predicate, object and graph label of an RDF Triple and the graph it is part of in a dataset. These may be separated by white space (spaces <code>#x20</code> or tabs <code>#x9</code>). This sequence is terminated by a '<code>.</code>' and a new line (optional at the end of a document).
