Dear All,

Thanks for you comments.
I attach a new version of the diagram.

I've addressed most of the comments:

- Single colon is used instead of '::' to represent namespace scoping
- vcard is no longer the range of siteAddress (in the absence of a range,
I've used rdf:Resource, is this OK?)
- navigability is always shown
- foaf:Group is aligned vertically with foaf:Agent

With respect to the aesthetics, I am not in favour of using rounded
corners, as this would no longer be a UML diagram. I am in favour of
standards :-)
Drop shadows are not possible in the tool.

About clickable parts, this is just a matter of making an area map in
html. I can do that once we agree on the diagram.

Regards,
Joćo Paulo
