The Open Science Monitor aims to measure progress in open access (OA) to scientific resources: publications, data and code. Its first edition in 2019 by the Ministry of Higher Education, Research and Innovation focuses on scientific publications.

The Open Science Monitor

According to  the January 2021 edition of the Baromètre de la Science Ouverte (BSO, Open Science Monitor), 56% of the 156,000 French scientific publications (according to authors’ detected affiliations) published in 2019 are available in open access. In a year, the rate of openness of 2018 publications has increased and now exceeds the 50% mark.


The Open Science Monitor (aka BSO) is a survey which measures progress in OA scientific resources: publications, code and data. This initiative is part of the National Open Science Plan and France’s National Action Plan within the Open Government Partnership (OGP).

It has been developed for publications only in an initial phase, and will provide further analyses on the OA share in French affiliated institutions’ publications (i.e. those which are made openly available on public websites) over time and measured by publishing venues and disciplines. The monitor will also help identify differences between OA publications according to venues: publishers or open repositories like HAL archive.

The BSO is a compilation of open data (from Unpaywall, a global database of scientific publication metadata that provides information on the openness status of publications) obtained using an open methodology. Thus, the underlying data is available under an open licence, its code is open source as well and its methodology is discussed in detail in an OA publication.

The BSO will be updated in December every year.  Each update in December of current year N will include the results for the scientific work published in year N-1 together with updates for previous years (N-2, N-3, etc.). A Flash note from the Ministry of Higher Education, Research and Innovation will announce each update edition of the BSO and highlight key trends.
