re3data, a global registry of research data repositories (RDRs), has aided researchers for over a decade. It offers a comprehensive directory of over 3,000 RDRs, supporting open science and data management initiatives worldwide.
Area of Science:
- Information Science
- Open Science
- Scholarly Communication
Background:
- re3data has operated for over ten years as a global registry for research data repositories (RDRs).
- It serves as the world's largest directory, describing over 3,000 RDRs using a comprehensive metadata schema.
- The service is integral to finding, identifying, and referencing RDRs for diverse stakeholders.
Purpose of the Study:
- To reflect on the ten-year experience of operating re3data.
- To discuss key issues in managing an Open Science service for global RDRs.
- To highlight the role of re3data in promoting open data and research integrity.
Main Methods:
- Utilizing a comprehensive metadata schema to describe RDRs.
- Providing advanced search and filtering capabilities for users.
- Making RDR descriptions available as Open Data via an API.
Main Results:
- Currently describes over 3,000 research data repositories.
- Supports searching across all disciplines and repository types.
- Facilitates the utilization of RDR data by numerous Open Science services.
Conclusions:
- re3data is a vital Open Science service supporting global research data infrastructure.
- The management of such a service involves addressing complex issues in data governance and accessibility.
- Its continued operation and integration into institutional policies underscore its importance in the research ecosystem.
