The actors of Open Science at the CNRS

The DDOR: a functional CNRS department

The Open Research Data Department (DDOR) was created in 2020. It is under the authority of the CNRS Scientific Office (DGDS) and is the result of the merger of the CNRS’s Scientific and Technical Information Department (DIST) and its Computing-Data Mission (MiCaDo).

The Open Research Data Department (DDOR) develops and implements CNRS policy on data in the broadest sense of the term, whether the data comes from experiments or simulations, is in the form of texts, documents or software or is included in publications. Overall, the department works towards openness in research as defined by the Roadmap for Open Science and the Research Data Plan.

Its working scope covers digital computing and data infrastructures, associated tools and services (data management, curation, documentation, referencing, repositories, making resources available and promotion), publishing and scientific publications. It is particularly responsible for building a joint strategy with CNRS partners and ensuring the consistency of this policy with national, European and international initiatives.

Its governance is based on a steering committee in which the ten CNRS institutes are represented and which works on establishing a common open science strategy for all scientific communities.

The three CNRS units under the authority of the DDOR

The Institute for Scientific and Technical Information

This is a CNRS research support unit that facilitates access to information and its analysis and mining while also promoting the dissemination of scientific production (publications and research data).

The Center for Direct Scientific Communication

This is a CNRS research support unit whose mission is to provide the French Higher Education and Research (ESR) community with the right tools to archive, disseminate and promote scientific publications and data.

CCSD Website


This is a support and research unit under the supervisory authority of the ENS Lyon and the CNRS which is supported by the Ministry of Higher Education, Research and Innovation. Its main mission is to promote document heritage for the benefit of research by carrying out its dissemination, enrichment and preservation.

The HAL open archive

This is a French multidisciplinary open archive developed by the Center for Direct Scientific Communication (CCSD) for the deposit and dissemination of scientific articles (whether published or not) and theses. This is an essential archive for the dissemination of knowledge from the entire French scientific and academic community

Huma-Num (INSHS / IN2P3)

This is a very large research infrastructure (French acronym – TGIR) in the humanities and social sciences. It was developed by the « UMS des Humanités Numériques’ (Digital Humanities joint service unit) and provides a set of services for digital data produced by the HSS.

Huma-Num Services

There is a dedicated service for every stage of the data life cycle – processing (shared toolbox), preservation (Huma-Num-Box), digital processing for access to and interoperability of humanities and social sciences research data, sharing (Nakala), unified access services (ISIDORE) along with a long-term archiving procedure.

OpenEdition (INSHS)

This is an infrastructure for research on open electronic publishing in the humanities and social sciences developed by the OpenEdition Center joint service and research unit (CLEO). It provides four platforms for open access publishing and information – journals, books, research notebooks and announcements of international academic events in the HSS.

Metopes (INSHS)

This is a research infrastructure working on methods and tools for structured publishing managed by the ‘Digital Document’ Unit at the Social Sciences Research House (MRSH).

It is designed for use by public sector publishers and to serve the publishing activities of all public higher education and research institutions. Its main mission is to provide a set of tools and methods to organise the production and dissemination of open access publishing products.

Progedo (INSHS)

A very large research infrastructure (French acronym – TGIR) working on the production and management of humanities and social sciences data led by the CNRS and the School of Advanced Studies in the Social Sciences (EHESS).

The TGIR Progedo’s mission is to develop data culture and drive a structured data policy for HSS research communities. Its development strategy has brought together research organisations, major institutions and universities while strengthening France’s position in the European research area.

Strasbourg Astronomical Data Center (INSU)

The Strasbourg Astronomical Data Center (CDS) is a national research infrastructure whose mission is to collect, homogenise, disseminate and preserve astronomical information to benefit the international scientific community.

It plays a major role in the development of the Astronomical Virtual Observatory (VO) at national, European and international (IVOA) levels.

Data Terra (INSU)

Data Terra is a research infrastructure whose mission is to facilitate access to data acquired from the ground and space for the study of the four compartments of the earth system (atmosphere, oceans, deep earth and continental surfaces). It also offers interoperable services and advanced products.

Data Terra’s research areas

Data Terra provides a unified and coherent portal based on four data hubs (Aeris, Odatis, ForM@Ter and Theia) along with associated transversal services and tools. These favour the intelligent use of data, indicators and models which come from national and international observation systems. All of this is essential for the implementation of sustainable development objectives.
