The following types of activities qualify for financial support, provided they are cost effective and have a clear link to the topics directly relevant to Fediversity and the objectives set out in the call:

• scientific research;
• design and development of open source software and open hardware;
• validation or constructive inquiry into existing or novel technical solutions;
• software engineering aimed at adapting to new usage areas or improving software quality;
• formal security proofs, security audits, setup and design of software testing and continuous integration;
• documentation for researchers, developers and end users;
• standardisation activities, including membership fees of standards bodies;
• understanding user requirements and improving usability/inclusive design;
• necessary measures in support of (broad)er deployability, e.g. packaging;
• participation in technical, developer and community events like hackathons, IETF, W3C, RIPE meetings, FOSDEM, etc. (admission fee, travel and subsistence costs);
• other activities that are relevant to adhering to robust software development and deployment practices;
• project management;
• out-of-pocket costs for infrastructure essential to achieving the above.

Project results must be made available under a free and open source license, so anyone can read and validate the source code, and anyone can use the code to create technology that fits their own purposes.
