Hello,
using the sportdb machinery (gems, command line tools and build
scripts in ruby) I've put together a [new free public domain dataset
for the (football) world cup in Russia 2018 [1]. The world's biggest
(sport) event kicking off in about a week.
Enjoy the beautiful game with ruby and datasets in json or sql :-).
PS: Find the [(activerecord) sql to json script [2] in the yorobot
automation repo.
