Between Collections and Data. Engaging GLAM Institutions in a Federal Open Science Ecosystem through FedOSC

This is the slide deck presented at the ADHO DH2026 in Daejeon, South Korea, on July 30, 2026. The presentation looks at how GLAM institutions (galleries, libraries, archives, museums) fit into Open Science. GLAM data are created to document and preserve collections rather than to answer research questions, so they often sit outside standard research data frameworks despite their research value. The talk presents FedOSC, an initiative connecting Belgium's Federal Scientific Institutes around Open Science, and focuses on its work engaging the GLAM community, from surveys and interviews to institutional assessments, first achievements, lessons learned, and next steps in building a learning community and practical RDM guidance.
