Hi Jose,

Thanks for your comments. Responses in line.

I've updated the text for each of these. I hope you'll approve of the
changes :-)

As for naming particular products (Pellet), we don't normally do this in
W3C specifications as it can be taken as unfair endorsement.

I can see your propsed mechanism. Since the changes will cause significant
disruption to the ontology, and to the code to extract the document, I'd
like to understand why you think this is a better approach. Can you
explain for me? There seems to be no advantage that I can see to doing it
this way
over the current approach. To me the current approach introduces less
coupling too.

+1 to this unless anyone objects!

Do we need to define any particular mechanism? Why not simply leave it
open. Why should we force people to have a FOAF profile before they can
submit properties?
