The 6 finalist works of the Barcelona Dades Obertes Challenge First edition_2018 have had an exhibition space, with the support of posters, within the context of the BigSurv18 Congress that has been held in Barcelona between the 24th and 27th of October. The representatives of the Ferran Tallada Institute, winner of this First edition with a project called 'Social cohesion goes by neighbourhoods', attended during the morning of Friday all the questions that the congressmen from around the world directed to them. The organizing team of the congress, leader by Antje Kirchner, chairwoman of the organizing committee, had, from the first moment, a great interest for this innovative initiative whose main objective is to introduce the open data as a resource to the educational centers of the city. The Barcelona Dades Obertes Challenge is led by the Ajuntament de Barcelona, together with the Consorci d'Educació de Barcelona and CESIRE.
