what exactly should that dataengine with nepomuk? (odds are it already exists 
or a good basis for it anyways)

for the ui it's very likely.
could still be possible having parts in c++ tough

yes, you should do the dataengine first and have most f the logic there.as i 
said that's very likely it exists, as the "metadata" dataengine in plasma 
active. it visualizes the results of a query, and since the data is always 
extracted with a query...

yes, you should do it in qml
