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.
Jsme si vědomi toho, že je vybudována s ohledem na demokracii, a proto je demokracie velkým zaměřením. Jádrem návrhu jsou demokratické principy, jako je zodpovědnost, rovnost a transparentnost.

Digitální platforma Decide Mérida byla příležitostí, která se otevřela jako nikdy před mechanismy účasti občanů na vypracování plánu rozvoje měst Mérida 2018-2021. Měli jsme více než 3000 občanských interakcí včetně návrhů, připomínek, návrhy a podporu, aby bylo dosaženo co největšího konsenzu o tom, co je nejlepší pro naše město. Bezpochyby bude platforma „Decide Mérida“ i nadále naším spojencem při vytváření participativní společnosti města Mérida.

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.

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.
