[annotator-dev] NLP Interchange Format (NIF)

Wed May 9 14:45:37 UTC 2012

Hi all,
two minor additions:
1. sorry I forgot the "Hi Nick and everybody," in front of my last 
email. I hope nobody took offense.
2. Below is a syntactically correct version of the annotations,  the 
other one had errors.
all the best,
Sebastian
