You are free to write about it elsewhere. As far as the OVC is
concerned, we treat it as public domain, but you can certainly write
it up and publish it where you see fit. However, until we've gotten
a chance to review the document and analyze and accept (or modify)
the data model, it should not be represented as the OVC's data model.
I'll be happy to do some of that analysis in a few weeks, but I'm not
ready to do that now.
