Résumé
Participatory policy making, in multi-stakeholders, inter-sectoral and multi-level contexts, isan intricate process which requires addressing various needs, constraints and steps.Moreover, beyond the in-presence protocols which we have implemented, for a sake ofsocial extension (“massification”), autonomization and compliance with current practices, theswitch to digital solutions is obviously required. For participants who are often reluctant toengage in a long, complex and sometimes doubtful pathway, it appears crucial to supportthem step after step in the decision procedure, to value and share all knowledge producedon the way and thereby to improve the efficiency of participation. Ultimately, based on thebackground of some CoOPLAGE authors, we aim at implementing Artificial Intelligencesolutions, i.e. multi-agent based support for participation.In terms of public policy support and transitions, the ultimate goal is to value the largeexperience of the CoOPLAGE tools and case studies, to transfer it in a generic platformopen for all stakeholders, which would give them the capacity to design, pilot, participate,evaluate some integrated participatory processes. It should propose solutions beyond theexisting large set of participation platforms with a focus on the global CoOPLAGE decisioncycle (cf. part yyy). It should value the transversal role of participatory modeling (cf. partxxx), support the process of “participatory engineering of participation” (part zzz) andimplement its following steps. As such, it is intended as a coherent “companion” to processmanagers and participants, which should strengthen the actual mobilization of participationin democratic decision making, and foster trust between citizens and institutions. Thesegoals raise several research and design questions, mainly related to the integration of stepsand tools in the procedure, and to the capitalization of knowledge.We discuss in a first part the target implementation context and a reference use scenariowhich shaped the design. In the second part of this chapter, we describe the structuralchoices, the architecture and finally we discuss ongoing evolutions. This chapter isstructured as a design document and not as a scientific contribution, which will come later inthe experimental phases.
