Our primary customers are enterprise data systems in which open world
semantics are key to doing database and other data integration via
inference. And then they also need validation fo the resulting data
integrations for which closed world semantics (and unique name assumption)
are vital. Needless to say, there isn't really a widespread consensus on
this question.

Our approach to RDF validation employs both closed & open world because
that's how the real world seems to work. See http://docs.stardog.com/icv/
for more details.
