They say: once there’s a paper 📝, it’s real…
🎉 #MEDem in #EPS @ecpr.bsky.social

The paper outlines how MEDem will strengthen #OpenScience by making data #FAIR in #DemocracyResearch – and how scholars across Europe are joining forces to build a truly open #ResearchInfrastructure ⚙️
Screenshot of the article “Open science in democracy research: the research infrastructure ‘Monitoring Electoral Democracy’ (MEDem)” published in European Political Science. The header shows the journal name, DOI link, and the label “DEBATE.” Below, the title is followed by the author list: Hajo Boomgaarden, Alexia Katsanidou, Sylvia Kritzinger, Georg Lutz, Johanna Willmann, and Jakob-Moritz Eberl. The abstract explains the aims of MEDem as a European research infrastructure to make democracy research data FAIR (findable, accessible, interoperable, reusable). Keywords listed include open science, FAIR data, ESFRI roadmap, research infrastructure, democracy research, data harmonization, data linking, and data set search. DOI: https://doi.org/10.1057/s41304-025-00534-8
