"Reference" query engine - this simply executes the algebra expression as-is using a simple (non-scalable) execution strategy that follows the definition of SPARQL as closely as possible. The reference query engine does provide the algebra extensions.

        return execRef(op, DatasetGraphFactory.createOneGraph(graph)) ;
    }


    static public QueryIterator execRef(Op op, DatasetGraph dsg)
    {
        QueryEngineRef qe = new QueryEngineRef(op, dsg, ARQ.getContext().copy()) ;
        return qe.getPlan().iterator() ;
    }
