Ben and Sebastian have both been looking at the datamodel for the core. I intend to focus short-term on testing current PG 7.1 pre-beta sources with an eye to building a stable snapshot we can share (as the latest CVS sources frequently break in minor ways on a day-to-day basis), and then to start looking at the datamodel.
Personally I'd like us to have a beta-quality port of the core not long after PG 7.1 goes beta (say in a month maybe?) and a full port of everything by the time PG 7.1 is released early next year.
It would be nice to have a more aggressive schedule but at the moment I don't see it happening.
