    • getRdfValue

      org.eclipse.rdf4j.model.Value getRdfValue(V value, PropertyIdValue propertyIdValue, boolean simple)
      Returns an RDF value that should be used to represent the given Wikibase data value in RDF.
      Parameters:
      value - the value to convert
      propertyIdValue - the property for which this value was used; this provides important context information for the conversion
      simple - if true, use a simplified conversion to RDF and do not convert values that are inherently complex
      Returns:
      the RDF value to use for representing the data value in RDF

    • writeAuxiliaryTriples

      void writeAuxiliaryTriples() throws org.eclipse.rdf4j.rio.RDFHandlerException
      Writes auxiliary triples that might be needed to encode a Wikibase value in RDF.
      Throws:
      org.eclipse.rdf4j.rio.RDFHandlerException - if there is a problem writing the triples
