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.
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.

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.

The Decide Mérida digital platform was an opportunity that opened as never before the mechanisms of citizen participation for the elaboration of the Municipal Development Plan of Mérida 2018-2021. We had more than 3,000 citizen interactions including proposals, comments, suggestions and support that achieving the highest consensus possible about what is best for our city. Undoubtedly, the Decide Mérida platform will continue to be our ally in making Mérida an increasingly participative society.
