Hi Reto,

If you take a look at the discussion of justifications for decisions in 
the Content section of the User Requirements document 
There's a notion of using provenance to justify why a system presents a 
particular outcome, in your case Why something is both a cat and a 
flying object.

Also, in the News Aggregator Scenario, there's a notion of a seal 
(similar to the "oh yeah button") where users can find out why a post 
was constructed in a particular fashion.

I hope that clarifies things.
