Are there any public data sets for the World Cup in Brazil 2014?

Didn't find anything for download on the official FIFA site (besides a single-page PDF booklet for the match schedule).

Ideally the data set includes groups, teams, players, squads, matches, stadiums and so on and is in an open plain text format such as CSV (comma-separated values), JSON (javascript objects), SQL (structured query language), etc.

Any insight appreciated.
