このプロセスは、2019年10月に欧州委員会の科学・知識サービスである共同研究センターのコミュニケーション総局とeDemocracyユニットで始まりました。会議のニーズを分析し、どのツールがそれに適合するかを検討した結果、技術的な成熟度、幅広いコミュニティ、適応性を考慮して、オープンソースのツールDecidimを選択しました。

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.
