Simplify the RDF::Writer method if you have already an rdf graph like:

```ruby
    @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 simply use:

```ruby
    RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
      writer << @rdf
    end
```

instead of:

```ruby
    RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
      @rdf.each{|statement| writer << statement}
    end
```
