Description
This Horizon Europe Coordination and Support Action (CSA) supports the development of a unified European hub for Open Internet Stack components and projects. The call aims to ensure the long-term sustainability, visibility, and compliance of open source digital infrastructure in Europe. Activities include cataloguing and reviewing open source solutions, performing security and accessibility audits, advising on sustainability and licensing, creating training materials, and developing a cohesive branding and communication strategy. The action also seeks to build links with national and pan-European open source initiatives, promote EU compliance (e.g., GDPR, DSA/DMA, CRA), and establish mechanisms for continued support and recognition (such as open source awards) beyond the grant's duration.
