A webinar from the EDUC-WIDE Seminar Series From Data to Code: How Libraries advance Open Science practices on source code Through Data Management Clusters PDF version link to reusable files Seminar Series Abstract In their general policy on Open Science, the University of Rennes encourages its researchers to archive their source code in Software Heritage, link source code to publications deposited in HAL to improve visibility, use standards such as SWHID to connect publications and source codeHowever, most of the source code produced by our researchers is likely hosted on GitHub, often without an explicit license permitting reuse, and has not been made visible on our University’s HAL Portal, which is managed by the Library. Our researchers can rely on a Data Management Cluster (ARDoISE) to help them manage and share their datasets in accordance with the FAIR principles. As a librarian at my university and, within ARDoISE, the person responsible for advising researchers on source code management and visibility, I will provide an overview of the efforts being made to address these challenges within our research community. I will also describe some of the steps we have already taken to foster collaboration with other stakeholders qualified to guide researchers on source code management. Additionally, I will outline potential future opportunities to increase compliance to our university’s Open Science policy regarding research source code.
