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.

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 ⚙️

Open science in democracy research: the research infrastructure “Monitoring Electoral Democracy” (MEDem) - European Political Science Ensuring universal access to scientific research and upholding the principles of keeping data findable, accessible, interoperable, and reusable is of paramount importance to the democratization of science. However, upholding these principles becomes increasingly complex with the increasing scope of data collection, the more different types of data we collect (e.g., survey, text, or institutional and country-level macro data), and the more research teams are involved in data collection. In the domain of democracy research, scientists across Europe are therefore joining forces to launch the research infrastructure monitoring electoral democracy (MEDem), which aims to establish itself as an open platform where the fragmented crowd of researchers in the various research fields can coordinate and develop common standards for data collection both retrospectively as well as prospectively to make their data interoperable, and (comparative) democracy research more productive. Moreover, MEDem will help make democracy research data and findings accessible to the general public (e.g., citizens, journalists, and policymakers).
