com.github.jsonldjava.core.RDFDataset.addTriple()
Adds a triple to the @default graph of this dataset @param subject the subject for the triple @param predicate the predicate for the triple @param value the value of the literal object for the triple @param datatype the datatype of the literal object for the triple (null values will default to xsd:string) @param language the language of the literal object for the triple (or null)
