Comment 17 for bug 264122

Actually, to get most of the data we have you can fetch our complete language pack source tarballs (get a "base" pack from https://translations.launchpad.net/ubuntu/intrepid/+language-packs). We also have a lot of data for previous Ubuntu releases, and a lot of data that is only considered as translation suggestions.

Since all of the translations we have now are either coming from upstream projects' translations or from Launchpad (which are in BSD), there is no legal problem with us sharing all the data, and we'd be happy to do so. The only problem at this time is actually doing the work to share it all (there are some legal issues about sharing our database model, but that is going to be resolved in the coming months when Launchpad is made free software).

What you are actually interested in is https://blueprints.launchpad.net/rosetta/+spec/rosetta-fuzzy-merge (that one is pretty incomplete, but we've already have some ideas on how to approach the problem). If you are interested in collaborating on the topic, we'd be very happy to talk about it.
