Open-Sourced ERP using Zope
IEEE IT Professional: ERP5: A Next-Generation, Open-Source ERP Architecture
Thanks to Mark for bringing this to my attention. These people have come up with a very robust, open-sourced ERP system using Zope.
It's very gratifying to read about their architecture and see some of the components they're using, because they are the same ones that we chose recently on a Zope/Plone project we're working on. And to think all of those components are now also available to Zope developers, that's a marvelous gift.
