public static void main(String []args)
{
    // Create an empty GraphStore (has an empty default graph and no named graphs) 
    Dataset dataset = DatasetFactory.createTxnMem() ;
    
    // ---- Read and update script in one step.
    UpdateAction.readExecute("update.ru", dataset) ;
    
    // ---- Reset.
    UpdateAction.parseExecute("DROP ALL", dataset) ;
    
    // ---- Read the update script, then execute, in separate two steps
    UpdateRequest request = UpdateFactory.read("update.ru") ;
    UpdateAction.execute(request, dataset) ;

    // Write in debug format.

    // Different style.
    // Equivalent to request.add("...")
    UpdateFactory.parse(request, "LOAD <file:etc/update-data.ttl> INTO GRAPH <http://example/g2>") ;
    
    // And perform the operations.
