To Serve and Protect
Having infrastructure is important, but it is nothing without somebody, who will operate it. The service provider for the Registrants is the Registration Agencies. They allocate prefixes, register the DOI names and provide the means for the Registrants to declare and maintain metadata and state data. In addition, some of the Registration Agencies offer many other related services like database management and take care of the quality assurance connected with the DOI registration.
