   RDF

      RDF is a standard model for data interchange on the Web,

      or in an RDF store; see

   TRTL

      A textual syntax for RDF that allows an RDF graph to be written
      in a compact text form, with abbreviations for common usage
      patterns and datatypes; see `<https://www.w3.org/TR/turtle/>`__.
