Hi Volker,

Thanks a lot for your perspective and input.

There is one question which your mail did not answer for me: Which kind of 
query language do you propose we use? I understand Akonadi supports two 
languages, SPARQL and something else, according to what Till once told me?

Would you advocate usage of SPARQL?

That seems awfully complex to implement on all clients.

Some more input on this would really be appreciated.

Meanwhile, allow me to respond to your question:

Resource types are email, calendar, contact, task, journal and anything else 
that may in the future be stored on a Kolab Server.

Whatever we come up with should really work for all of them.
