Understand, and sorry for the misunderstanding on my side. The tricky 
part will be the API design, when we have to define return types for 
e.g. getCreator . Of course we could say "text or URI", but what happens 
with the URI? Is it resolved? What happens if the resolution does not 
lead to RDF data but to an image? And so on.

Not sure if this is the way to go ... applications of the API need to 
know what do do with the return types. And trying to guess whether
is an URI pointing to a local copy of my foaf file is really hard.

Agree. My impression is that we will have this discussion mostly when we 
look into specific methods and discuss useful return types - useful for 
hopefully many applications.
