RE: question on domain

Thinking out loud here... 

It seems that schematron (which I do like by the way) would be only
useful in validating a RDF/XML instance after the fact (outside of the
RDF parser).  It also would not be much help with non-XML RDF syntax.

It would be nice to be able to actually validate that a class instance
according to its schema within the parser (after the model has been
built and the syntax disappears).  But, from the other posts to my
question, it seems that I may not have fully considered the
ramifications of the "open world" mentality that was mentioned earlier.
Does this mentality really mean that validation, in the sense of "a
person MUST have a name", is too restrictive and that, if necessary, it
should be done within the application?

By the way, thanks again for the help on my original question.

Try something like Schemarama.
