That's correct, please fork it, and try hacking together a prototype
so we have a starting point ;-) Of course you'll have questions,
you're welcome tu use this mailing list or IRC.

Some more information is on the Wiki; see especially

And while the following link is related to Hibernate Search, it has
some guidelines about how the patches and tests should be:

(I guess I should copy that over to OGM, or reorganize it in a common area)

Most of these Wiki pages are relatively new; you're welcome to edit
them, and add details you might get from us / looking at the code
which you think should have been there.

Last step, you should sign the contributor agreement for the Hibernate
project at cla.jboss.org; you could wait for your work approval to
sign a corporate one, or you can just sign a personal one. (you can
sign the other as well later).
