        RDFService getShortTermRDFService()
        Returns an instance of RDFService that may not support being left idle for long periods of time. RDFService instances returned by this method should be immediately used and closed, not stored in (for example) session or context attributes.

The results provided by RDFService instances returned by this method must be identical to those provided by instances returned by getRDFService().
        Returns:
        RDFService - an RDFService instance
