Markus, speaking of this, it'll be great to hear you plans on query access to all the meta-data of the pages (so i can get rid of DPL extension ;)).

Glad to hear that. We are always interested to learn about new applications
and use cases.

This is a bug, or at least a known limitation. The upcoming SMW-Version takes
care of passing these triples to RAP as well, so the problem should go away
with the upcoming release (after the mandatory refresh). I did not try RAP in
the current SVN version yet, but it might actually work already. It might
also just cause some errors, so keep your working copy of SMW before trying
it.
