Gang, I've started to put up a list of status for all the DA's on the web site: http://www.zope.org/Download/DAStatus Please look over this and let me know if you have anything to change. I will be adding information about contributed DAs as it is collected/contributed. One thing I would like to make clear about all DC-supported DAs... they will all be at least Level 2 by the official release of Zope 2.0. In addition, if you wish to beat a DA into L2 immediately, all you need to do is: * Mix in the Shared.DC.ZRDB.THUNK.THUNKED_TM instead of normal one * Call self._register before you do a query * And implement self._begin, self._finish, self._abort This gets you L2 + integration with transaction support. This list will expand and grow over the next couple of days. Chris
