Sure. I meant this as a trial balloon. I agree that unless we have an idea
which is the larger group needing OWL Lite, the argument should not be based
*solely* on RDF.

Personally, I'd fall into the latter group -- using OWL Lite given the
efficiency of implementation. On the other hand my applications will likely
tend to have a DL bent, coming from the healthcare arena.

I am not saying that we should change things, rather acknowledging that
there is a cognitive difficultly in migrating from RDF Schema to OWL Lite --
indeed such folks might be better off migrating from RDF Schema to OWL Full
in many cases, and perhaps we ought warn folks a bit better about this
potential issue.
