Geography rules.
I’ve been trying to work out some sort of concensus for how to include location info in FOAF files. It seems that my current implementation is too US-centric. The folks in the UK don’t like the use of the “StateOrProvince” terminology. I’m going to try switching to vCard terms (“Locality”, “Region”). vCard also has support for lat/long coords, so that might be better all-around.
