Your approach shows the significance of the RDBMS/SQL paradigm for any inference-based query answering system. A query and inference server for RDF should basically provide at least as much expressivity/functionality as a SQL-DB server (including negation-as-failure, as opposed to the views of the "conservatives" on this list). -Gerd
