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.
Pràcticament cada procés participatiu que ens ha arribat, l'hem pogut resoldre utilitzant les regles de negoci de Decidim. És una eina molt potent. No obstant això, la part que ens sembla més forta i important és la seva comunitat, tant de desenvolupadores com d'aquelles persones que la utilitzen per a processos participatius. Conviure amb aquesta comunitat ens ha fet dimensionar els desafiaments que comporta implementar la democràcia participativa en el món real.

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.

Els principis democràtics com la rendició de comptes, la igualtat i la transparència estan en el centre del disseny. Decidim és està construït tenint al cap la democràcia, és el seu gran focus.
