        ModelMaker maker = ModelFactory.createMemModelMaker();   
        Model m = maker.createModel(BASE, false);
               
        //load owl file in model M
        FileInputStream  fis = new FileInputStream (getClass().getClassLoader().getResource("file.owl").getFile());
        m.read(fis ,null);
        fis.close();

       
        //TODO: if exist BASE in virtuoso FAIL
        //to erase datas conductor SQL> RDF_GLOBAL_RESET ();
        Model m2 =vd.getNamedModel(BASE);
        if(m2 == null)
            vd.addNamedModel(BASE, m);
