Very sound advice and keen observations ... you're right! Time will tell and
we need to start making some baby steps in the right direction for now. I
think involvement with the Maven people in defining what a repository is for
one single Apache repository is most important first.
Extention of this repository with artifact attributes to enable the application
based characterization of artifacts is the next step. The POM can be stored
there and so can other application specific deployment attributes if the Maven
people want to go there. The nice thing is if done right we can query for
these artifacts based on their attributes to build a very powerful base to all
The ideas to come out of Maven and Merlin regarding a repository and its use
are very powerful. Maven invented it and Merlin showed us how to use it to
manage an environment. Both are very powerful innovations.

The technical details will come together but let's do it right as one
community. I think this is where the [EMAIL PROTECTED] list is going. In the
words of that great American hero, G.I. Joe, "that's half the battle."
