re3data.org API

re3data.org, the Registry of Research Data Repositories, describes research data repositories (subjects, content types, access and licence conditions, persistent identifiers, certificates) and serves its records as XML through a keyless REST API.

Required Attribution:

Not required for the CC0 database entries. The site gives a citation: "re3data.org - Registry of Research Data Repositories. https://doi.org/10.17616/R3D"

Coverage

Descriptions of research data repositories, not the datasets they hold. The about page says the registry "is global and covers all research disciplines" and that "Its records are available as XML, structured by our schema that is maintained and regularly updated with community input." History start and update frequency: Not stated.

Verdict

Keyless XML REST API (re3data.org/api/v1) for research data repository descriptions. Licensed CC0-1.0 for the database entries: the about page says: "re3data shares all of its metadata as open data without restriction using Creative Commons Zero, and it provides an open application programming interface (API) and other protocols to encourage sharing and integration." and "To the extent possible under law, re3data.org has waived all copyright and related or neighboring rights to the database entries of re3data.org." Other site content is under CC BY 4.0 except where otherwise noted. Distinct from the datacite-rest-api entry (DOI metadata). Rate limits: Not stated. Signal Lab links only.
