This is a topic that came up at the conference, and has come up over
time on the mailing lists.
To help answer questions about this I've written up some details and
put together a diagram which is now available on this page on the docs
site:
http://docs.ofbiz.org/display/OFBADMIN/Component+and+Component+Set+Dependencies
All committers should understand this pattern, and of course we should
refine it over time. Hopefully this will help us have, and understand,
a little more order in our efforts to organize components.
Please send along comments! This is a first draft and I'd like to
discuss it and such so we can move toward following the patterns and
making this a "policy" of sorts.
