Sounds sensible.

I have one concern tough:

How is importing / exporting / sharing between several computers handled? 
How can I access the data without an application? How transparently for me 
it is stored?

I use Basket, which only allows manual exports/imports of one basket 
(including sub baskets). But then I know the stuff is in 
~/.kde/share/apps/basket and I can backup it, I can copy it completely to 
a different machine.

Maybe its just lack of understanding or ignorance till now, but how can I 
understand how to transport / backup / copy my note data, when it is 
scattered around Akonadi and Nepomuk? Can I tell Akonadi or Nepomuk to 
just export the note stuff. How would I manage to get a synced copy of 
Akonadi and Nepomuk stuff regarding notes. Can I export it to one file?

While I really like the Akonadi and Nepomuk approach of the application 
doesn't have to care on how relations and data is stored, I fear to be put 
a bit out of control as a user cause I myself have no idea where it is 
stored either anymore. To me it partly feels like putting lots of stuff 
into a black big container without knowing how to extract the data without 
the means of an application. Baskets note storage is really easy to 
understand and I could use the data even if basket would be gone. How is 
that with Akonadi / Nepomuk data? Another example would be an 
OpenDocument? That format is easy to grasp and I can use the information 
even without OpenOffice.org or Koffice.

This is not just related to a note taking application. Maybe this should 
be brought elsewhere? Or I can add a meta bug about this? Or ask that on a 
Akonadi / Nepomuk related mailing list.
