Peer Community In and Peer Community Journal: from preprint recommendation to diamond open access publication

Peer Community in (PCI) offers a free and transparent alternative to traditional scientific publishing by creating researcher communities that evaluate and recommend preprints. Recommended preprints can then be submitted to journals or published directly in the diamond open access Peer Community Journal. Since its launch in 2017, PCI has grown to 20 thematic communities, uniting over 2,500 scientists and supported by more than 200 institutions worldwide.

Managing and sharing research data

Over the past decade, funders and legislators have taken steps to improve the management of data produced in scientific research and promote its widest possible sharing. These incentive policies have had a significant impact on scientific practices, notably by increasing transparency and raising the profile of research. In response to these new challenges, several French and European institutional mechanisms are being established to raise awareness and support research teams on a daily basis.

Software Heritage: Building the Software Pillar of Open Science

Software Heritage stands as the largest public archive dedicated to software source code and its associated development history. As of September 2025, it has successfully archived over 25 billion unique source code files and 5 billion commits, originating from approximately 400 million collaborative development projects. In this presentation, we will provide a brief introduction to the Software Heritage initiative, followed by an in-depth exploration of its unique role within the broader open science community. Software Heritage ensures the availability and integrity of source code artifacts essential for any field that relies on software for conducting experiments, thereby significantly contributing to the reproducibility of research.

Workshops

Reproducibility Crisis in Science and Possible Solutions

The reproducibility crisis in science refers to the difficulty in replicating many studies, primarily in psychology, medicine, and biology, which undermines confidence in published results. This workshop will provide an opportunity to discuss (1) the methodological issues that have led to this crisis and (2) the editorial (by scientific journals) and publication (by authors) practice changes that could help address it.

Preserving the World’s Software: A Hands-On Introduction to Software Heritage

Software is a cornerstone of our scientific, cultural, and technological heritage, yet it is fragile. Software Heritage addresses this challenge by building a universal archive of source code dedicated to the collection, preservation, and sharing of humanity’s software legacy. It provides automated and manual archiving options, stable identifiers (SWHIDs) for precise citation, and ensures that both source code and its development history remain accessible for the long term.
This workshop offers a hands-on introduction to Software Heritage and how to integrate it into your own workflows. Participants will learn how to search and reference archived software, cite it properly in academic contexts, and automate preservation using “save code” webhooks for platforms like GitHub, GitLab, and Bitbucket. By the end of the session, attendees will be equipped with practical tools to safeguard their own software while contributing to the preservation of the world’s software heritage.

Pimp my IDs

Researcher identifiers have become essential tools for improving the visibility, accessibility, and interoperability of research results. This workshop invites you to (1) create, enrich, and align your identifiers (e.g., ORCID, IdHAL, IdRef, Arxiv author identifier, and Scopus ID) and (2) share best practices for using identifiers and managing your digital identity.

Practic'HAL

You've heard about HAL, but haven't submitted an article yet. You deposited an article in HAL before, but you ran into some difficulties. You want to create your IdHAL or learn more about your online résumé. You would also like to learn about advanced features, such as updating your ORCID account with your HAL deposits, deposit suggestions, and linking resources to your publications (datasets, code, etc.). We will be available to answer your questions during these practic'HAL sessions. 

How to identify and avoid predatory journals and conferences

The phenomenon of predatory journals and conferences is growing to the point that it is affecting the quality and credibility of scientific work. This workshop provides an opportunity to share best practices and useful tools for identifying and avoiding predatory journals and conferences.
