Felix,
Yes and Yes.  Maintaining the turlte can be low priority, we need 
something formatted as a W3C note to accompany the RDF/XML, that we keep 
consistent with the RDF comment that Sebastian suggested.

What were you using to edit the RDF/XML.

Sorry I couldn't make the call, but it looks like we are making strong 
progress.

Good interest here at the Open Data on the Web event from the GDL 
working group in taking further.

cheers,
Dave
