So we envisaged to express avalable rating values as SKOS: Concept(s).
This is a rather simple approach; I agree. We could think of including a 
more complex rating scheme as well (e.g. something similar to the PICS 
rating scheme or the review vocabulary)

We envisaged the encoding of positions via a Location concept which we 
introduced (see hasLocation(Location)). The Location concept is however 
not yet specified. We didn't get too far with discussion of the shape of 
the concepts we introduced (also Person, etc. is rather underspecified 
currently).

Best,

Tobias
