Taken from a different angle, this issue might be caused by the lack
of a domain specific way to say that a "document sucks" as opposed to
saying that a "person sucks". Disambiguating everything is a pipe
dream IMO. We would be much better to focus on domain specific
vocabularies, as the RDF user can actually choose what to utilise for
the property even if they can't always disambiguate the object URI
they are focusing on.

Cheers,
