I think this is a great idea. I noticed, for example, here:

http://smw.referata.com/wiki/Main_Page


Discussion of the concept of a SMW 'package': "which are collections
of wiki pages defining properties, templates, forms etc. that can be
imported into one's wiki to create an instant data structure."

It really seems like such 'packages' (object models) should be 'self
describing' on the wikis that use them. i.e. the components of the
wiki used to construct such models should be associated with the
appropriate semantic markup, allowing the object to be exported via
RDF.
