Tiny changes on the /ns files

Gregg,

while preparing for publication I ran into a link checker issue; this led me to look at the csvw.jsonld files. I realized that the /ns files included links from the RDFa initial context that it should not have. Indeed, the initial context file[1] includes some prefixes that are only flagged as potential future standard vocabularies, ie, users are warned not to use those prefixes. These include ptr, gldp, etc. But these are not standardized (yet?), for their namespace links may not even dereference (this is the case for gldp, which led me down to this). I.e., those should not appear as part of the initial context and the /ns files; I removed those from the ns files in the repo (and the metadata draft to be published).

Thanks!

Ivan
