OK, that very sounds sensible. Unless there are objections, let's do that.

I don't like that as we don't want people to have free choice. They 
really MUST use either FOAF or dcterms. Your union of the Agent classes 
looks like the one to me - it matches the mood of last week's f2f and 
has the benefit of you having had time to think about it more than we 
did a week ago.
