CrossRef Workshop, Gauteng, South Africa, September 2015 6 The organization of DOI registration 11 International DOI Foundation (IDF): oversees the central DOI system, promotes the DOI as a standard, and provides an organizational infrastructure that ensures persistence and interoperability. Corporation for National Research Initiatives (CNRI): they (among other things) are responsible for the Handle system, which is the technology that causes DOIs to resolve to the registered URL Registration Agencies (RAs): Register DOIs on behalf of other organizations. CrossRef is a RA. Registration Agencies • Airiti • CrossRef • China National Knowledge Infrastructure (CNKI) • DataCite • Entertainment Identifier Registry (EIDR) • The Institute of Scientific and Technical Information of China (ISTIC) • Japan Link Center (JaLC) • Multilingual European DOI Registration Agency (mEDRA) • Publications Office of the European Union (OP) Different registration agencies provide different services They all provide the basic DOI linkage service
