Wow - I'm surprised at the conclusion... doesn't seem to me that S
(described in your email linked to above) is a good choice (though I'm
admittedly more concerned with how useful RDF is for soving problems than in
how well a group's charter is met). What of the RDF that's been written to
date that doesn't conform to this? what of rdf that will written in the
future when one doesn't know the datatype of a property?
