    Load RDF data into an RDD[Triple].

    Load RDF data into an RDD[Triple]. Currently, N-Triples, N-Quads and Turtle syntax are supported.

    lang

    the RDF language (N-Triples, N-Quads, Turtle)

    Load RDF data in RDF/XML syntax into an RDD[Triple].

    Note, the data will not be splitted and only loaded via a single task because of the nature of XML and how Spark can handle this format.

    returns

    the RDD of triples
