I am pleased to announce that a database has now been set up for the Wikimedia Commons.
The site is temporarily located at http://commons.wikimedia.org/ until the project gets its own domain.
This provides a space for those interested to begin forming the guidelines for the site, and to discuss how the software will need to adapt to make the Commons as useful as possible.
The previous discussions are now linked to from http://commons.wikimedia.org/wiki/Commons:Project_plan.
Batches of files may be uploaded as compressed zip files. Some time in the next few days, a script will be written to decompress these zip files on the server side. Please make sure you use appropriate file names inside the archives.
Thanks to Tim Starling for creating the database, and to all those who have contributed to the discussion so far.
Angela.
