DataCite

DataCite is a registration agency for the Digital Object Identifier (DOI) system that specialises in research outputs other than journal articles, particularly research data, software, samples, instruments, and other long-tail scholarly objects. It was founded in London in December 2009 by seven institutions, including the British Library, Purdue University, and the California Digital Library, with the goal of making research data citable and discoverable on the same footing as papers. Members assign DOIs to digital objects and deposit rich metadata describing what each object is, who produced it, where it lives, and how it can be reused. Metadata follows the open DataCite Metadata Schema, which supports relationships such as `IsSupplementTo`, `IsDerivedFrom`, and `Cites`, allowing networks of datasets, code, and papers to be expressed in machine-readable form. Author ORCID iDs and institutional ROR identifiers can be embedded in records, enabling cross-system analytics. DataCite is the standard DOI provider for many institutional and disciplinary repositories, including Zenodo, Dryad, and Figshare. It works closely with Crossref on shared infrastructure such as event tracking and reference linking, and participates in open scholarship initiatives like the Initiative for Open Citations (I4OC). The organisation now has hundreds of members across 25 or more countries.
