A platform designed entirely with free software, open and collaborative content thanks to the Metadecidim community.
The communityThe 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.

What we appreciate is that it’s built with democracy in mind and therefore democracy is a big focus. Democratic principles such as accountability, equality and transparency are in the core of the design.

New York participatory budgeting has grown to a point that we needed better tools to facilitate the conversations that were happening across the city. We have grown from 4 city council members to 36 and now the people have voted (to dedicate agency?) to participatory budgeting. We looked at what was available and Decidim was the tool that met our aspirations in NYC. 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.
