The Plan for Open Science mandates that all research publications from publicly funded projects be deposited in open-access repositories and encourages making research data openly accessible. The first National Plan for Open Science was adopted in 2018 and then extended with the Second Plan in 2021 to span until 2024 and beyond.
Researchers are encouraged to follow FAIR principles in managing and sharing research data, fostering the sharing and reuse of data. The plan supports the development of national infrastructure for open science, including the HAL (Hyper Article en Ligne) repository for publications. Researchers are required to deposit their publications in open access repositories, such as the HAL, immediately upon publication, which enables free access by default. This applies especially to research funded by public grants, and researchers are encouraged to make data available by default unless restricted by legal or ethical considerations.
The Second French Open Science Plan primarily adopts a Green Open Access approach by requiring immediate deposition in repositories. While Gold Open Access is supported in part by APC funding, there is a strong preference for using repository-based access and exploring alternatives to high APC fees.
