Wikimedia Commons is a database of freely usable media files with more than 32 million files. As of August 2016, total size is over 84 TB (check).

Archiving process

Tools

• Download script (Python)
• Checker script (Python)
• Feed lists (from 2004-09-07 to 2008-12-31; more coming soon)

How-to

Download the script and the feed lists (unpack it, it is a .csv file) in the same directory. Then run:

• python commonsdownloader.py 2005-01-01 2005-01-10 [to download that 10 days range; it generates zip files by day and a .csv for every day]

Don't forget 30th days and 31st days on some months. Also, February 29th in some years.

To verify the download data use the checker script:

• python commonschecker.py 2005-01-01 2005-01-10 [to check that 10 days range; it works on the .zip and .csv files, not the original folders]

Tools required

If downloading using a very new server (i.e. a default virtual machine), you got to download zip (Ubuntu: apt-get install zip)

Python should be already installed on your server, if not then just install it!

Also has a dependency on curl and wget, which should be installed on your server by default...

Volunteers

Please, wait until we do some tests. Probably, long filenames bug.
