      call in interface JsonLdTripleCallback
      Parameters:
      dataset - The format of the dataset is a Map with the following structure: { GRAPH_1: [ TRIPLE_1, TRIPLE_2, ..., TRIPLE_N ], GRAPH_2: [ TRIPLE_1, TRIPLE_2, ..., TRIPLE_N ], ... GRAPH_N: [ TRIPLE_1, TRIPLE_2, ..., TRIPLE_N ] } GRAPH: Is the graph name/IRI. if no graph is present for a triple, it will be listed under the "@default" graph TRIPLE: Is a map with the following structure: { "subject" : SUBJECT "predicate" : PREDICATE "object" : OBJECT } Each of the values in the triple map are also maps with the following key-value pairs: "value" : The value of the node. "subject" can be an IRI or blank node id. "predicate" should only ever be an IRI "object" can be and IRI or blank node id, or a literal value (represented as a string) "type" : "IRI" if the value is an IRI or "blank node" if the value is a blank node. "object" can also be "literal" in the case of literals. The value of "object" can also contain the following optional key-value pairs: "language" : the language value of a string literal "datatype" : the datatype of the literal. (if not set will default to XSD:string, if set to null, null will be used).
      Returns:
      the resulting RDF object in the desired format
