I’ve extracted from Sportbook  the football fixtures (including
schema & models) for easy reuse. The open sports database also
includes a command line tool, that is, sportdb and a sample web admin
tool in Ruby on Rails.
Events in the sport.db include the Champions League 2012/13, Euro
2012, World Cup Quali and others.
The sportdb gem also ships with a plain text fixture reader for easy
data import. For samples, see the English Premier League  or the
Deutsche Bundesliga  fixtures.
