RDFParser

public class SPARQLUpdateDataBlockParser
extends TriGParser

An extension of TriGParser that processes data in the format specified in the SPARQL 1.1 grammar for Quad data (assuming no variables, as is the case for INSERT DATA and DELETE DATA operations). This format is almost completely compatible with TriG, except for three differentces:

• it introduces the 'GRAPH' keyword in front of each named graph identifier
• it does not allow the occurrence of blank nodes.
• it does not require curly braces around the default graph.
