Strengthening Open Science Practices Through re3data, the Global Registry of Research Data Repositories

For more than a decade, re3data (, the global registry of research data repositories, has helped researchers, funding agencies, libraries, and other research data services to find, identify, and reference research data repositories. As the world's largest directory of data repositories, re3data describes over 3100 infrastructures on the basis of its comprehensive metadata schema in May 2023. The service allows searching for research data repositories of any type and from all disciplines, and users can filter results based on a wide range of characteristics. The re3data descriptions are openly accessible via an API and are reused by numerous open science services, including DataCite Commons. re3data is engaged in various initiatives and projects concerning data management and is mentioned in the policies of scientific institutions, funding organizations, and publishers.

The presentation will focus on the growth, development, and accomplishments of re3data over more than 10 years that have resulted in re3data becoming the most comprehensive information and metadata resource on research data repositories. Further, the presentation will address how re3data’s activities can support the establishment of best practices, support open science, and facilitate networking within different research communities. With over 850 entries the field of geosciences is one of the most strongly represented subject groups in the registry.
