NIF 2.0 is a major, not backward-compatible improvement upon the previous version NIF 1.0.

There has been an ongoing debate about '#' vs. '/' . We focus on ontologies with '#' here with URIs like: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#String Note that ontologies with '/' URIs need to published differently (partly discussed here: http://lists.w3.org/Archives/Public/semantic-web/2013Apr/0157.html).
