[NLP2RDF] [Dbpedia-discussion] ANN: NLP Interchange Format (NIF) 1.0 Spec, Demo and Reference Implementation

Tue Nov 29 14:35:35 CET 2011

Hello Michael,
I am forwarding your email to the NLP2RDF mailing list and added you to 
it, if you don't mind.
Christian Chiarcos from OLiA is also on the list and might answer your 
questions.
Perspectively, that is exactly how we imagined NIF to evolve.
You could write a blog post proposing your extensions and then other 
people can comment and it will be improved over time.
If it is mature and implemented we can integrate it in NIF.

All the best,
Sebastian
