Hi all,
If you look at the quarterly goalshttps://www.mediawiki.org/wiki/Wikimedia_Engineering/2012-13_Goals#Milestones_by_quarter_14 announced by the Wikimedia Engineering and Product Development department you can see implementation of the Configuration databasehttps://www.mediawiki.org/wiki/Requests_for_comment/Configuration_databaseas 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
