Hi, Sebastian,
I’ve been trying to address similar issues to what you describe for a couple of
years now.
This is the best I’ve been able to piece together.
Hopefully it can be useful in your new efforts.

Tim

walks a “good” VoID description and down-codes it into the CKAN JSON using the
lodcloud group’s conventions [1].

(special thanks to ww’s modeling in
https://bitbucket.org/ww/gold/src/c4104d81ec30/ckanclient/ which used to be
hosted at semantic.ckan.net…)
Prizms [2] nodes [3] dereference their own VoID metadata [4] and update their
datahub.io listings every week [5].
(They also notify Sindice when they publish new datasets, but that’s a
different topic…)
