Hi all, 

If you look at the quarterly goals announced by the Wikimedia Engineering and Product Development department you can see implementation of the Configuration database as a goal for the first half of 2013. Configuration should be easier and less fragile with the database replacing .php config files. The database seems particularly interesting for wiki farms. Take a look, share your opinion, and follow its development. 

P.S. You can learn about other interesting projects going on from the goals page. 

Regards, 

Mariya
