Yes, we were working in some client applications, and we needed some
changes.

Nowhere. There were no active forum at that time to discuss our proposals
(that was one of the reasons to push for an open source nepomuk)

Yes, we needed them to implement some real use cases (i want to emphasize
that are Real-World needs).

 We did our extensions carefully: trying to follow the nepomuk philosophy
and keeping the consistency of the ontologies. However, there are usually
more than one possible solution for each problem, so we would really
appreciate comments about our proposals. (This was a second reason for the
open source approach)

Yes, of course. I planned to do that once the svn was reorganized (start to
write tickets about our changes)

IIRC the changes are:
1) NMO: added the mimeparts of a message to represent correctly emails
2) NMO: added mail account information
3) NMO: added RSS feed support
4) NMO: added IM support
3) Some changes in property ranges here and there
4) New ontology for downloads and transfers (MTO at the moment)
5) A draft of location ontology (MLO at the moment)
6) NMM: new ontology to unify multimedia representation
7) Some extensions for FM Radio support (not sure those are commited yet)
8) Web history support ( http://live.gnome.org/Tracker/WebHistory )
9) Different solution for lists (implemented on playlists)
...

And maybe more. We put quite a lot of effort using/developing the ontologies
:)

Regards,

Ivan
