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.
We suffer under a lack of public space. It's particularly important that we reclaim these public spaces for us. Open platforms such as Decidim do exactly that. Is not only that is open source so other people can fork it, reuse it and build a process. It also has these values that we want to reflect in our society encoded in the way it's designed.

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.

Fast jeder partizipatorische Prozess, der an unseren Tisch gekommen ist, ist es uns gelungen, ihn nach den Geschäftsregeln von Decidim zu lösen. Als Werkzeug ist es ein sehr starkes Werkzeug. Der Teil, der uns jedoch am stärksten und am wichtigsten erscheint, ist seine Gemeinschaft, sowohl Entwickler als auch diejenigen, die es für partizipative Prozesse verwenden. Die Koexistenz mit ihnen hat uns veranlaßt, die Herausforderungen zu erkennen, die mit der Umsetzung der partizipatorischen Demokratie in der realen Welt verbunden sind.
