The DataCite Registration Agency is making metadata for digital objects that have been assigned a DOI identifier through the agency available through the DataCite Metadata Store, in line with its commitment to the POSI principles.
One of the ways the agency makes metadata publicly available is through a public data file. In late January 2025, the agency published for the second time a dataset containing metadata for the 72 million DOIs that had been registered through DataCite by the end of 2024.
In 2024, the DataCite community registered more than 19 million new DOIs. DataCite members have also submitted updates for more than 10 million existing DOIs – encompassing metadata improvements that enhance the completeness and quality of DataCite metadata:
- Connection metadata: Of the DOIs registered in 2024, over 58% have at least one ROR ID and over 61% have at least one ORCID iD. These identifiers make it easy to analyze links among works, people, and organizations.
- New resource types: In 2024, we released Schema 4.5 and Schema 4.6, introducing new resource types: Instrument, StudyRegistration, Project, and Award. So far, 20 organizations have already made use of these newly added resource types.
- New organizations: Over 100 organizations registered their first DOI in 2024, including both Direct Members and Consortium Organizations.
