You might want to look at the DBObjects/SmartObjects development. DBObjects
already allows direct ORMapping, including more restrictive QueryFolders, a
History with Undo functionality (in CVS), Volatile/Persistent Mode, XML-RPC
Support and much more.
DBObjects Home Page: http://demo.iuveno-net.de/iuveno/Products/DBObjects
(Note: The DBObjects Demo is using the older versions.)
DBObjects CVS: http://imail.iuveno-net.de/CVS/cvsweb.cgi/DBObjects/
Accessing the CVS via SSH:
cvs -d ":pserver:[EMAIL PROTECTED]:/cvs" login
password anonymous
cvs -d ":pserver:[EMAIL PROTECTED]:/cvs" checkout DBObjects
I am not the CVS expert, so let me know if it does not work.

Stephan
