CoSO — Comité pour la Science Ouverte
Overview
The Comité pour la Science Ouverte (CoSO) is the French interministerial committee responsible for coordinating and implementing the national open science policy under Ouvrir la Science. Created in 2018 by the Ministry of Higher Education and Research (MESR), CoSO brings together representatives from all major French research organisations, including CNRS, Inserm, ANR, CPU/France Universités, IRD, INRAE, and others, to develop guidelines, promote best practices, and track progress on open science implementation across French publicly funded research. CoSO is the operational governance body of Ouvrir la Science: it drafts policy documents, coordinates thematic working groups, manages the Fonds National pour la Science Ouverte (FNSO), and interfaces with European open science initiatives including EOSC and OpenAIRE.
Structure: Four Colleges
CoSO operates through four thematic colleges, each addressing a pillar of Ouvrir la Science:
College Publications
The Publications college addresses open access to scientific publications, including implementation of Plan S and cOAlition S in France, diamond open access journal support via the FNSO, HAL mandate compliance and HAL institutional portals, and preprint and rights retention strategies.
College Research Data
The Research Data college addresses FAIR Principles implementation for French research data, Recherche Data Gouv development and governance, DMP mandates via OPIDoR, disciplinary repository alignment, and EHDS national implementation for health data.
College Europe and International
The Europe and International college coordinates French participation in EOSC governance and service development, alignment with European open science initiatives and cOAlition S, and international open science policy engagement.
College Competences and Training
The Competences and Training college covers open science literacy in researcher training at doctoral schools, the development of the data steward profession, training resources via RDMkit and OPIDoR, and evaluation reform aligned with the San Francisco Declaration on Research Assessment.
Key Outputs
CoSO’s principal output is the Second National Plan for Open Science (2021–2024), which it drafted and monitors the implementation of (see Ouvrir la Science). It manages the FNSO (Fonds National pour la Science Ouverte), through which it funds diamond open access journals, open software, and open science training initiatives. CoSO also runs a current project on transparency and publication of health research results (Transparence et publicité des résultats de la recherche en santé), addressing trial result reporting obligations relevant to ClinicalTrials.gov and CTIS registration requirements.
Membership
CoSO includes representatives from MESR (Ministry, secretariat), CNRS, Inserm, IRD, INRAE, INRIA, CEA, IFREMER (major research organisations), ANR (national research agency), France Universités (CPU, university network), CDEFI (engineering school network), RENATER (national research network), IFB, and CCSD (HAL operator).
