Who’s behind the platform?
Metadecidim is the community that collaborates in the design of the platform and the development of the project. Together we design and create new features and report bugs for continuous improvement of the platform.
The Decidim Free Software Association is a democratic association for the governance of the Decidim community.
The process started in October 2019 at the European Commission’s DG Communication and eDemocracy unit at the Joint Research Centre, the European Commission's science and knowledge service. An analysis of the needs of the Conference and which tools fit those, lead to choosing the open source tool Decidim for its technical maturity, broad community and adaptability.

Was wir schätzen ist, dass es unter dem Gesichtspunkt der Demokratie aufgebaut ist und daher die Demokratie ein großes Anliegen ist. Demokratische Grundsätze wie Rechenschaftspflicht, Gleichheit und Transparenz stehen im Mittelpunkt des Entwurfs.

Mit der Implementierung von Decidim in Som Energia haben wir einen freundlicheren Raum für Partizipation geschaffen. Wir haben das Tool 2018 freigegeben als Gastgeber der Generalversammlung der Genossenschaft und Monate später diskutierten wir das Image Redesign und die gemeinsame Entwicklung der Schule von Som Energia, unter anderen partizipatorischen Prozessen. In wenigen Monaten haben sich mehr als 3.500 Teilnehmer registriert, 5 Beteiligungsprozesse, Bei der letzten Generalversammlung stimmten 3 Versammlungen und mehr als 1.300 Stimmen.
