abstract class AbstractRDFGraphSpark[Rdf <: RDF, D, G <: AbstractRDFGraphSpark[Rdf, D, G]] extends AbstractRDFGraph[Rdf, D, G] with SparkGraphExtensions[Rdf, D, G]

A data structure that comprises a collection of triples. Note, due to the implementation of the Spark datastructures, this doesn't necessarily mean to be free of duplicates which is why a distinct operation is provided.
