Thanks Niklas for pointing out these resources.

As someone involved in more or less all of them (beside Jeni's blog,
obviously ;) I'd like to use this opportunity to give some updates and
clarifications:

Indeed. For a start I'd suggest people look at the voiD overview [1] and the
voiD guide [2]. Further we are currently working on voiD 2.0 [3], which we
intent to submit to W3C as a member submission.

Regarding dataset dynamics, we are working on a vocabulary [4] and a first
demo is available [5] as well. This is rather premature work, though a
couple of people seem to be interested and have gathered in a respective
working group [6].

Right. We are about to release a new version of Neologism very soon and
happy to keep you posted.

Cheers,
