I have been looking for formula one racing open data, but I haven't found anything...
I'd need open data about any sports or about topics like health, university etc... to build up a project of datawarehouse
Formula One racing open data (outdated) here: https://github.com/opensport/formula1.db
In general, Gerald Bauer has been compiling and releasing lots of sports open data. You can read about some of it here: http://okfnlabs.org/blog/2014/05/06/open-data-world-cup.html
