Re3Data.Org

It provides an organized index of repositories, with options to search and browse by subject, country, and repository profile. The site reports an index of more than 3,500 repositories and highlights newly added records, making it easier to explore the range of services available for storing and sharing research data.

The registry also supports research infrastructure through its metadata, data analytics, and API resources. Its collaboration with Research Resource Identification (RRID) aims to link repository records and improve interoperability, metadata quality, and completeness across scientific systems. re3data publishes guidance and information through its FAQ, schema documentation, editorial board, working group, and publications, and invites users to suggest repositories. The service is presented as the Registry of Research Data Repositories and can be cited through its DOI.
