Eurocities, this great network of European cities, has selected the Barcelona Dades Obertes Challenge initiative as the main example of the first principle of the "Decalogue of citizen data principles". It has also been related to principles 2, 9 and 10. The city of Barcelona is thus reinforced as a reference in the introduction of open data in the educational world.

Also World Data Viz Challenge Barcelona-Kobe is an highlighted project, in this case, within the group of other examples and also related to 1, 2, 9 and 10 principles.
