This sounds interesting for us, since you could use it to have your .tap
always uptodate, instead of just saving on shutdown. and other
interesting uses. The correct day is actually Wednesday.

We plan to have a Birds of a Feather (BOF) session at the Python 10
Conference, http://python10.org, on a Python persistence framework.
The Zope object database, ZODB, includes frameworks
for persistence and transaction management. These frameworks
depend very little on the rest of ZODB and will be factored
out of ZODB and made into separate packages in the next generation
of ZODB, ZODB 4.
The ZODB persistence framework provides significant benefits to
- Objects are automatically loaded and stored. The programmer
doesn't have to keep tack of when objects have been
modified. The objects track modification and notify the
transaction manager of changes. The transaction manager
coordinates storing data. Data are loaded when needed, with
loads triggered by access from other objects.
- An object cache automates moving data out of memory when no
longer needed. A cache invalidation protocol helps to keep object
consistence across multiple applications or application
We would like to see these benefits made available for other
databases. We'd especially like to see a persistence framework
using relational databases, reusing object-relational mapping
efforts, such as MiddleKit and others.
We'd like to kick off an effort to design a persistence framework
to encompass ZODB, relational databases, and other persistence
The BOF will begin with a presentation of the ZODB Persistence
The time and location are TBD. Check the BOF schedule when you get to
