	 * 	Example 1: Adding some triples to a graph

	This snippet describes two RDF triples to be inserted into the default graph of the Graph Store.

	PREFIX dc: <http://purl.org/dc/elements/1.1/>
	INSERT DATA
	{ 
	  <http://example/book1> dc:title "A new book" ;
	                         dc:creator "A.N.Other" .
	}

	Data before:

	# Default graph
	@prefix dc: <http://purl.org/dc/elements/1.1/> .
	@prefix ns: <http://example.org/ns#> .

	<http://example/book1> ns:price 42 .

	Data after:

	# Default graph
	@prefix dc: <http://purl.org/dc/elements/1.1/> .
	@prefix ns: <http://example.org/ns#> .

	<http://example/book1> ns:price 42 .
	<http://example/book1> dc:title "A new book" .
	<http://example/book1> dc:creator "A.N.Other" .
