The output is very similar: you can see the output of vocab2jena here:
https://gist.github.com/TreeRex/6464149
The main difference is that I use use the ResourceFactory methods instead
of creating the static Model. And I don't use the * wildcard on the imports.
So... I guess it would have behoved me to look at schemagen before I spent
a couple of hours writing my utility: it would have saved me the bother. I
saw the name in the docs and didn't connect it to what I needed. I should
have figured you guys would have done this already. :-/
