Re: RDFS schema files

Hi Bob,

In order to be able to generate the same structure in multiple
serializations (eg Turtle, N3, XML, etc) I build it in code and then
run it through the serializers.

So the exact nature of the output is somewhat out of my control.  When
it's finalized, we can hand-tweak it to be more easily readable.
