Today at the pre-camp meetup we talked about keeping in touch regarding our current projects in our individual departments... so, for anyone interested, here's what I'm up to at the Department of Family Medicine:
Migrating from a Drupal 5 multisite setup (with lots of abuse of Views 1's theming layer) to a single Drupal 6 site with Domain Access to control the separation of content (and maintainable use of Views 2).
The whole process is made more complicated by the fact that we want to keep the node IDs the same for several content types on one site, and by the fact that this is living content (it will continue to change up to the minute we make the switch). I looked at a number of different import/export solutions for this, but all of them were too buggy, unreliable, and tied strictly to the browser interface, so I've just written a bunch of quick-and-dirty PHP scripts to do the heavy lifting, plus a shell script to execute these scripts and other tasks via drush.
Improving the integration of our... unique... HR/personnel Oracle database, our rudimentary PHP Faculty & Staff Directory, and personal profiles in Drupal (Content Profile, Views of course, and an in-house custom module to interface with the aforementioned database). The custom module includes use of both the Batch API and the job queue module.
Taxonomy Access Control: We rely heavily on TAC, but the Drupal 6 version had a number of critical bugs. I scratched my own itch and patched them.
There are still a few outstanding issues and it's a complicated module to administer... if by any chance you use TAC in D6 and have problems or questions, check out the improved docs and the issue queue.
So, what are you working on right now?
