Social contract

It's yours. Use it. Share it. Improve it.

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

The 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.

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.

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.
