Forum OpenACS Q&A: Response to Karl's Templating System
You probably want http://www.arsdigita.com/bboard/q-and-a-fetch-msg?msg_id=0008ku&topic_id=155&topic=Publishing%20System. This is in the Publishing System Forum, not in web/db, which is probably why you couldn't find it. I've lost it a couple of times myself. :)
If you also look at http://www.arsdigita.com/bboard/q-and-a-fetch-msg?msg_id=0008wl&topic_id=155&topic=Publishing%20System you'll see that I asked some questions about the changes in 3.3/3.4 and the future of the content management piece of DPS, but they weren't answered. My impression is that Karl didn't do the integration into ACS 3.3 and doesn't know the answers, and whoever did isn't reading this forum.
If anyone does come across more information please post it! I'm working on a client proposal that includes DPS and it's very frustrating to not have a good handle on it's current state or future direction.
