openDCNSoftware
The openDCN project aims at promoting citizens participation and at linking citizens to their institutions and other decision makers with information products, a communication framework and, finally, an on-line deliberative space capable to involve them in the decision-making process, i.e. to define and put in action initiatives in the field of governance policies and sustainable development for their territory. The goal of the openDCN project is to enhance the effectiveness of participative processes by conceiving, designing and implementing a socio-technical, computer-enabled, trusted environment for e-participation and fostering the evolution of the classic community-network concept into a new consultative-deliberative paradigm.
