[NLP2RDF] NIF ontology: broken links

[Antonin Delpeuch (lists)]

Hi,

I was looking for the definition of the NIF format. It seems that it
used to be available at:
http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#

This link currently gives an HTTP 403 error for me. I found it in the
"Integrating NLP using Linked Data paper":
http://svn.aksw.org/papers/2013/ISWC_NIF/public.pdf
Given that this link appears in a published paper, I think it is very
important that there is an effort to maintain it (otherwise the
"persistence" in the domain name is not really deserved).

The same link is also used at:
http://persistence.uni-leipzig.org/nlp2rdf/

Thanks to Wikidata (https://www.wikidata.org/wiki/Q31794099) I was able
to find
http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core/nif-core.html,
which seems to be about NIF 2.0, what about NIF 2.1?

Best regards,
Antonin Delpeuch
