What license can I use to ensure open access to my research?

Research published in open access must be made available under an open license that allows others to freely use, modify, and share the work, while respecting the principles of research ethics. The most widely used and recommended open licenses are Creative Commons licenses, such as CC BY (Attribution) and CC BY-SA (Attribution + ShareAlike).

For certain types of research outputs, however, other licenses may be more appropriate. For example, Creative Commons licenses are not suitable for software, as they are not designed with software-specific requirements in mind. For software, researchers should use free and open-source software (FOSS) licenses, such as AGPL-3.0, GPL-3.0, EUPL-1.0, LGPL-3.0, Apache-2.0.
