Turtle serializer

I seem to be unable to serialize to Turtle when setting the format using serializer.format:Turtle.

I've skimmed through the issues, and saw this: #161
Does this mean that this generator will not be supporting Turtle any more going forward?
If so, what alternative methods would you suggest to serialize to Turtle?

Hi @rubensworks,

If your data sets sizes aren't huge, try the stable branch with Hadoop. That still has the Turtle serializer.

We're overhauling the code on the dev branch. Adding and RDF/Turtle serializer is on the list (#227) but has a low priority. So I cannot promise anything.

Thanks for the reply!
I'll try to use the stable branch for now then.
