There's the point.  Is it really necessary to create more
classes, more properties, and more triples in the data that is
actually published?

I also wonder about the training angle.  I think we want to
enable people to create application profiles pretty easily --
perhaps with menu-driven interfaces, and using their syntax
of choice -- yet in a way that ensures that their data will
play well as Linked Data.

Asking people to conceptualize their data in terms of class
semantics seems to set the barrier really high.  Explaining
the simpler notion of a Dublin Core application profile has
been challenging enough.  Should the design of good metadata
require knowledge of OWL?  Can OWL semantics really be stuffed
under the hood of a clever interface?
