+
+Simplify the RDF::Writer method if you have already an rdf graph like:
+
+    @rdf = RDF::Graph.new
+    RDF::Reader.for(format).new(rdf) do |reader|
+      reader.each_statement{ |statement| @rdf << statement }
+    end
+
+To parse it to another format simpy use:
+
+    RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
+      writer << @rdf
+    end
+
+instead of:
+
+    RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
+      @rdf.each{|statement| writer << statement}
+    end
+
+and use the base class RDF::Writer instead of subclasses like RDF::Turtle::Writer.
+It is much more time-efficient !
