Hi Susan, Do you need the entire database diff'd? I.e. all edits ever. Or are you interested in a particular subset of the diffs? It would help to know your purpose.
For instance I am interested in diffs around specific articles for specific dates to study news events. So I calculate the diffs myself using python on page histories rather than the entire database.

The Summer of Research folks provided a handy guide to how to create such a dataset from the standard complete dumps here: http://meta.wikimedia.org/wiki/WSoR_datasets/revision_diff But the time estimate they give is prohibitive for me (20-24 hours for each dump file--there are currently 158--running on 24 cores). I'm a grad student in a social science department, and don't have access to extensive computing power. I've been paying out of pocket for AWS, but this would get expensive. There is a diff-format dataset available, but only through April, 2011 (here: http://dumps.wikimedia.org/other/diffdb/). I'd like to get a diff-format dataset for January, 2010- March, 2013 (or, for everything up to March, 2013). Does anyone know if such a dataset exists somewhere? Any leads or suggestions would be much appreciated! Susan
