私たちは、パブリックスペースの不足に悩まされています。このようなパブリックスペースを自分たちのために取り戻すことは特に重要です。Decidimのようなオープンプラットフォームはまさにそれを可能にします。Decidimはオープンソースなので、他の人がフォークして再利用したり、プロセスを構築したりできるだけではありません。それに加えて、私たちが社会に反映させたいと考えている価値観がデザインされているのです。

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.
