personally, i prefer the idea of a nice API behind which the real work can 
hide (as the usercontext thing provides). direct access to what's going on in 
Soprano seems fragile and overly difficult to me from an application 
developer's POV.

another big question is what the ontology to use is. when i last left off 
discussing this with the nepomuk people there was a long discussion being had 
about what that ontology should look like. i'm not sure what the end result 
was, tbh.

personally, i favor something simpler and reflective of what we need rather 
than complex and theoretical. 

the big requirements we have in plasma is the ability to have a named 
"context" that can be associated with locations, people, documents ... 

context+location will likely end up being a pretty important pairing to at 
least some of our users since if i'm doing work related activities, what that 
looks like when i'm in the office vs in an airport is pretty different (e.g. 
vpn access, NDA'd documents, etc).

in any case, if the nepomuk team could give us some pointers to where the 
ontology for this ended up, that'd be great.

here is a document that Luca Beltrame had started on:

there may be useful things in there as well.
