When you are trying to work out how to model something, try consuming the RDF proposed. It pretty quickly becomes obvious what are some bad things to do. Either because you get the "wrong" answers, or because the queries you want to do are really hard. the you can concentrate on the choice from a few things to work out which is most "fit for purpose".
Just modelling on its own is pretty much worthless - if you aren't querying the resultant data, then the model has little value, since you are enacting a write-only process. Best Hugh
