<< Objectives >>DSEtools aims to deliver VET material for filling the knowledge gap between social and solidarity economy (SSE) actors (managers, entrepreneurs and workers) on the one hand, and open source communities on the other hand. It aims at enabling both populations to collaborate and co-design digital strategies meeting SSE principles and values of openness, democracy and sustainability.<< Implementation >>3 deliverables are foreseen: collecting best practices and consolidating them into a shared vision; designing a handbook; elaborating and promoting policy recommendations.Such deliverables will be produced and promoted during transnational events, involving project partners and external partners.<< Results >>This project will lead to the creation of a VET partnership between a European SSE network, and a transnational open-source community, together with their respective broader ecosystems. At the end of the project, both communities are expected to share collective knowledge and visions enabling them to design innovative digital strategies based on open-source and interoperable solutions, participating to the development of a sustainable and inclusive digital economy.
