+ <p>A graph statement pairs an IRI with a RDF Graph. It is intended that triple statements made about that IRI are being made about the graph. The triple statements that make up the graph are enclosed in <code>{}</code>.</p>
+
+ <p>In a TriG document a graph IRI MUST NOT be used to label more then one graph. The IRI of a graph statement may be omitted. In this case the graph is considered the default graph of the RDF Dataset.</p>
