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.
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.

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.

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.

Can I join the Metadecidim community even if I don't live in Barcelona?
Of course you can. People do so through participatory processes, debates, translations, etc. that you might find in Metadecidim. Decidim was born in Barcelona and that is why there is a strong territorial bond with this city, but above all, it's a project for the commons.
I have ideas for new improvement features. I want to have a better understanding of the project. What can I do?
You can collaborate in multiple ways. One of them is through the Metadecidim community. If you want to propose new features, go here. If you have detected errors and want to notify them, go to this process. If you want to actively participate in the Metadecidim community, you can attend Community Meetings. Register as a participant of the community and participate with us. If your thing is the code, come to Github. If you are a researcher, you might be interested in coming to the LAB Metadecidim Seminars.
