Open Data BCN takes part in the 12th Science Festival. You can find us at the 'Núvol de dades' space on Saturday the 9th where different activities concerning open data will take place. One of the innovations is the release of the interactive activity ‘Open Data per a “Dummies”’ where you could make an approach to this world in the most ludic way. Test yourself with any of the two paths we propose: ‘What do we complain about?’ and ‘Traffic accidents’. Surely it will surprise you!
