Did you think about using the deployment admin in this mix? I don't see a reason why you couldn't put deployment packages into an obr repository ... All we would have to do is to extend our client implementation a little bit to use the deployment admin to install the deployment packages. This way, you could have features that are deployment packages and could use obr to express dependencies between features (assuming there are any).
Just a thought. regards, Karl On Thu, May 7, 2009 at 8:47 AM, Guillaume Nodet <[email protected]> wrote: > Right, but I don't have much problems with OBR the spec, but mostly > with how it can be used now. > Repositories are huge xml files, slow to parse.
