About the call
CodeSupply supports R&D projects that improve the security and transparency of the software supply chain — one of the most vulnerable points in today's digital infrastructure. The goal is an open, reliable and secure internet stack that does not depend on hidden metadata or closed vendors.
The call looks for practically oriented new ideas and breakthrough technologies in the areas of: publishing up-to-date, accurate and comprehensive software metadata; a scalable and sustainable mechanism for democratic access to datasets; and a core framework for future releases, improvements and new datasets.
Eligible activities
- Open metadata for software packages, provenance and licensing;
- Tools for detecting and describing vulnerabilities;
- Tools for supply chain quality and security;
- Validation and constructive exploration of existing or new technical solutions;
- Open source code and freely available results.
