Software has become essential in all areas of scientific research, both as a tool for research, a product ofresearch, and a research object in itself. In the quest to make research results reproducible, and passknowledge to future generations, we must preserve three main pillars: the research articles that describethe results, the data sets used or produced, and the software source code that embodies the logic of the datatransformation. Indeed, the preservation of software source code is as essential as preserving researcharticles and data sets.The main aim of this in-person half-day event, organized by the French Committee for Open Science onNovember 29th 2023, was to bring together high-level stakeholders from a variety of backgrounds,including researchers, research software engineers, research evaluation bodies, infrastructures, academicopen source program offices (OSPOs), and financial backers, to share their experience and views onresearch software.The workshop featured three panel sessions, in which speakers focused on major dimensions of relevanceto software in open science:− Acknowledgment of software as a key pillar for reproducible research;− Recognition and support for the dissemination of software;− Highlighting of the social impact of software.
