Very much agree with that. Being able to say "OSGi spec
implementations happen at Felix, and
customizations/application-specific stuff/extensions etc. usually
happen in other projects" leads to a clear picture for "customers" of
Apache OSGi stuff (and BTW the incubation proposal forgot about Sling
apparently - we might use Aries' stuff as well in there).

I don't like the idea of having part of the OSGi specs scattered
around several projects - as a general rule. Several modules are now
at Felix that were initially developed by the communities of other
projects (ServiceMix, Slng, ACE), and moved to Felix once recognized
as being "of general interest to OSGi users" - I think that's a very
good model both for ASF insiders and outsiders.

Several projects in the history of the ASF have granted commit access
to committers of other projects on parts of their codebase. That
wouldn't be a new thing. Forrest committers, for example, have commit
rights on Cocoon, but they're expected to ask before changing stuff in
there, to make sure Cocoon folks know what's going on.

That works well, IMHO, and maybe Felix could similarly open parts of
their codebase to other OSGi-related projects, with the same
convention of "just let us know before making changes in there" and
"make sure you're following our dev list".

I know such issues can be discussed during incubation, not necessarily
before the podling is accepted, but the fact that (AFAIK) no contact
was made with the Felix project before creating the Aries proposal is
very disturbing - so IMHO we should rather clarify this before
accepting the podling.

Maybe simply saying "modules that implement OSGi specs, or that are of
general interest to OSGi users, will be moved to the Felix project, as
much as possible" in the Aries proposal would help. That should be
true for any project doing OSGi at Apache anyway, and I think the
other projects mentioned above are working like that, which is a Good

I'm very happy to see Guillaume as a mentor for Aries, that will
hopefully help in building bridges between Felix and Aries.
