Registration Agencies


The primary role of Registration Agencies (RAs) is to provide services to Registrants — allocating DOI® name prefixes, registering DOI names and providing the necessary infrastructure to allow Registrants to declare and maintain metadata and state data. This service is expected to encompass quality assurance measures, so that the integrity of the DOI® system as a whole is maintained at the highest possible level (delivering reliable and consistent results to users). This includes ensuring that state data is accurate and up-to-date and that metadata is consistent and complies with both DOI system Kernel and appropriate Application Profile standards. See also examples provided by several Registration Agencies.

Current Registration Agencies are listed below, with their areas of coverage and links to the organizations for requesting more information. New Registration Agencies are being added, and suggestions for additional sector coverage are welcome.

  • DataCite is focused on working with data centres and organisations that hold data. The details of their business models, workflows, and other requirements do not appear to be identical to those of publishers producing traditional journals.
  • DataCite has a business model that meets the needs of non-commercial and sometimes smaller organisations; larger national-scale organisations (e.g., TIB, BL) carry the basic infrastructure costs and will reclaim where appropriate within their domain.
