Terms will be added to the DOI Kernel Schema at the request of any Registration Agency (RA) by the modification of the Metadata Kernel and/or its Allowed Values, or the publication of other DOI message schemas in addition to the Metadata Kernel. Any RA may add new values to the open Allowed Value Sets (AVS) by registering them with the DOI Foundation. To do so, the procedure is as described in Creating or Updating a Metadata Schema.
