+ The <a>Cut</a> operation is used to remove one or more triples from the <a>target graph</a> connected to a specific RDF node (an IRI or a blank node, potentially through a bound variable). The triples being removed correspond to the <a href="http://en.wikipedia.org/wiki/Connectivity_%28graph_theory%29">connected graph</a> accessible from the given RDF node through blank nodes, and following the direction of the predicates.
