DPG is inspired by the concept of Digital sovereignty, which has emerged as a promising governance approach to ensure that digital economies are innovative, inclusive, and trustworthy. Digital sovereignty is about enabling and promoting data generation, sharing, and reusing, and establishing open and trusted data alliances within and between industries and countries. Shared data spaces are essential drivers for a competitive, yet inclusive digital economy. They can help economies to leverage advanced technologies like cloud/edge computing, artificial intelligence, knowledge graphs, digital twins, Internet of Things (IoT)/smart sensors, 5G, and distributed ledgers. However, most small digital players from business (startups and SMEs), civil society (citizens, NGOs, and academia), (local) government and state agencies have constrained resources and typically have limited data; therefore, they cannot easily develop and offer their own services. Digital sovereignty is about lowering the barriers to entry and encouraging the emergence of equitable peer-to-peer platform ecosystems.
