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.

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.

La plataforma digital Decide Mèrida va ser una oportunitat que va obrir com mai els mecanismes de participació ciutadana per a l'elaboració del Pla Municipal de Desenvolupament de Mèrida 2018-2021. Vam tenir més de 3 mil interaccions ciutadanes entre propostes, comentaris, suggeriments i suports que van donar lloc al major consens possible sobre què és el millor per a la nostra ciutat. Sens dubte, la plataforma Decide Mèrida continuarà sent la nostra aliada per a fer de Mèrida una societat cada dia més participativa.
