Hi,
I am about to start implementing p2 publishing support in b3 engine.
My approach is to use the p2 ecore model in the aggregator, and hoping
that there is code there that I can just call.

Two questions...
- The p2 model is nested at the moment. Should we break it out into its
own bundle?

- Once I have populated a p2 model, how to I write it out as a "p2 repo
on disk" ?

Sorry for late answer. Comments inside. I can help with implementing the changes if you like.

Yes, I think that it would be nice to share one common p2 model for everything in b3.

Currently we can only read a p2 repository into the model. We have "importToModel" methods which scan the original p2 structure and copy it into the EMF model. Perhaps we need to write inverse methods to push the model into a native p2 repository instance to be able to store it.
