I'm in the nepomuk-kde channel already if you want to ping me there at some 
point.

Yes, that's a bit long term stuff, that I'm not aiming for this week or 
anything, but I just want to use stuff that will make it possible in the 
future without too much fuss.

My initial reaction to this is that it shouldn't be necessary to attempt to 
synchronize notes stores in nepomuk and akonadi. Having such a resource 
would mean that semnotes would be using akonadi anyway, and then it would 
make more sense to access the shared data instead of copying/synching, no? I 
say that without knowing enough about how the stuff is stored in nepomuk, so 
I may be missing a few important points.

Right. My understanding was that these relations would be stored in nepomuk, 
and the notes themselves in akonadi. That way it would be possible to create 
relations in kjots too.

Accessing the notes from akonadi directly would bring that for free, but 
might impose other things that you may not want, such as heirarchical 
structure of note collections, having to either choose a collection of notes 
to deal with at a time, or otherwise deal with all the data in the tree and 
having to handle notifications of new notes being added etc. 

If your idea was that all notes from akonadi would be synched into nepomuk, 
those are issues you would need to deal with anyway though.

Cool, well it would be cool for us to talk on irc before that if possible 
too to flesh out more ideas.

All the best,

Steve.
