Baromètre Français de la Science Ouverte
Overview
The Baromètre Français de la Science Ouverte (BSO, also known as the French Open Science Monitor) is an open-data dashboard developed by the French Ministry of Higher Education and Research (MESR) to track the progress of open science practices across French publicly funded research. Launched in 2019, it measures and publishes annual statistics on open access to publications, open research data, and open source software, providing the empirical evidence base for French open science policy implementation under Ouvrir la Science. It is built entirely on open data and open-source methodology, with all code available on GitHub, making it a model of open science applied to open science monitoring itself.
What It Measures
The BSO tracks open access to French scientific publications, measuring rates by year, discipline, publisher type, and funding source, with a breakdown by access type (gold, green via HAL, hybrid, bronze) and compliance rates with ANR Open Science Policy mandates. It also measures the proportion of French publications with associated open data statements and tracks deposits in Recherche Data Gouv and discipline-specific repositories. For software, it monitors open source publication rates and Software Heritage deposits.
Technical Implementation
The BSO uses Unpaywall and OpenAlex for publication open access status, HAL metadata for French repository deposits, DOI resolution for publication identification, and DCAT and Dublin Core for dataset metadata. All source code: https://github.com/dataesr/bso-publications (publications) and https://github.com/dataesr/bso-ui (interface).
Institutional Adaptations
The BSO methodology has been adapted by individual institutions to create local open science monitors. BSO3 is an institutional version deployed at universities and research organisations including Inserm, CNRS, and Sorbonne Université. Institut Pasteur has its own local adaptation. These local monitors feed into the national BSO aggregation.
