And it uses a wiki - correct?

Peter,
An open repository for models of all forms (RDF, OWL, UML, BPMN, XSD,
etc) is exactly where we are going with the open source "Enterprise
Knowledge Base" (http://portal.modeldriven.org/project/EKB).  This is
still in an early state but what it offers today is the ability to
"check in" models (using subversion) and have these converted (if
required) to RDF-LOD and published as a SPARQL and point along with a
simple model-browser UI.
You can get a subversion account on the sample server and try it out.
We have A LOT of ideas for where to go with this - almost too many
options.  We are looking for feedback on the most important use cases
and features to support.
Regards,
Cory Casanave.

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,
      Michael
