The document discusses Digital Social Innovation (DSI) and the Collective Awareness Platforms for Sustainability and Social Innovation (CAPS) initiative. DSI is important for society, the environment, the economy, and the development of the internet. It leverages people's creativity and involves participatory, bottom-up, decentralized, multidisciplinary, and open approaches to innovation. The CAPS initiative funds projects that harness digital tools and networks to create awareness of sustainability challenges and collaborative solutions. The 3rd CAPS call will fund projects engaging civil society to address sustainability through new economic models based on open data, sources, and hardware.
