Hi Paolo, I'll comment on the SPARQL question and leave the representation question for now. As you say below, I was imagining this would be a series of examples and template queries. It is a standard exercise but this is the sort of thing that makes people's life easier. Also, I imagine these could get fairly complicated for example relying on property paths. cheers, Paul >>>> 2.)
