Our apps use an open file format so you can do what you want with your data. It is YOURS, after all. If you do publish something, please make sure it's clear that it's your app, not ours.

On the other hand, we're still developing OmniFocus, so the file format probably will keep changing, and we won't necessarily announce every little change we make.

You're welcome to post questions about the file format here, or maybe in the OmniFocus Extras forum would be slightly better. I'll try to answer them if I can. However, our engineers are pretty busy finishing OmniFocus and probably won't have time to help.
