The year 2025 marked a significant milestone for the CCSD: 25 years of commitment to advancing open science, during which the CCSD has supported, and often anticipated, changes in scientific communication.
The annual activity report outlines the numerous initiatives undertaken and the significant progress made in promoting open, public, responsible and sustainable scientific publishing.
As every year, three key highlights are highlighted:
- The award of the international CoreTrustSeal certification to HAL, in recognition of its long-standing efforts in governance, data management, and compliance with international archiving and open science standards;
- A redesigned user interface for Sciencesconf conference websites, to make them more appealing and offer optimal navigation;
- The highly favourable mid-term evaluation of the Equipex+ HALiance project. The international jury identified this as a flagship achievement of the Investments for the Future programme, highlighting its scientific quality, technical robustness, and transformative impact.

About HAL
A total of 161,991 deposits with file were created in 2025. 5,704 of which were via the suggestion service. This equates to an average of 13,500 issues per month, which is a slight decrease compared to the previous year (-3.43%).
The trend of pooling resources within the higher education and research sector is continuing, with 153 institutional portals currently in operation, four of which were launched in 2025. These are the INSEE portal, the Burgundy Business School portal, the École Supérieure des Agricultures portal, and the University of Strasbourg portal.
Administrative changes have also led to the closure of certain portals: these include those of HESAM, Paris Lumière, and ENSTA-Paris and ENSTA-Bretagne, which have now been merged into a single ENSTA portal. In all these cases, the associated collections remain available and retain their historical records.
About Episciences
9 new journals have joined the platform, bringing the total number of journals to 45:
- Data et corpus : la revue des données en SHS
- Détours : Revue en didactique des langues et des cultures
- JETHro. Eran Turan and Hrom: A Journal of Global Late Antiquity
- JFP – Journal of Functional Programming
- JoNAS – Journal of Non-Associative Structures
- JSAT – Journal on Satisfiability, Boolean Modelling and Computation
- jSEDI – Journal of Studies of Earth’s Deep Interior
- MSS – Movement & Sport Sciences – Science & Motricité
- ToC – Theory of Computing
742 articles were published in 2025.
About Sciencesconf
3064 conferences were created in 2025, which amounts to around 12 new presentations per working day. A total of 90,802 papers were submitted, 20% of which were full-text papers.
Sciencesconf is the first of the CCSD’s platforms to migrate to new software infrastructure developed as part of the Equipex HALiance project. The new version of the database management system was migrated and installed over the summer. These operations will improve the reliability, performance and maintainability of the Sciencesconf data environment while ensuring an uninterrupted service for users.
The Equipex+ HALiance project
The year 2025 was marked by the drafting of the midterm scientific report and the CoreTrustSeal certification obtained for HAL. Other key highlights included the first component of the code migration put into production, consisting of the HAL CV, as well as the overhaul of the relationships system between resources in order to better highlight links between publications, data and software.
