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.

Part of what makes Decidim so powerful is that it adds a level of abstraction to the work separating out the steps of a process and the activities associated with the process. That’s part of the information architecture, so that not only you are saying what is happening at each step but different parts of Decidim behave differently depending on when you are doing or depending on what step in the process you are in. The fact that that’s customizable really allows Decidim to be moulded to how we are doing our work and not our work to be moulded.

Dank Decidim ist es uns in Barcelona gelungen, gemeinsam mit den Bürgern einen strategischen Stadtplan zu erarbeiten. 2016 haben wir den Stadtaktionsplan in Form eines partizipatorischen Prozesses durch Decidim Barcelona eröffnet. Derzeit umfasst dieser Plan fast 7 000 Vorschläge für Bürger. Einer der Vorteile der Nutzung dieser Plattform besteht darin, dass Sie jederzeit den Stand der Umsetzung der angenommenen Vorschläge überwachen können.
