Administration of Domain Name Service (DNS) registration increasingly distinguishes between operation of the data base for registrations, versus "front-end" sales and support services by registrars who interact with registrants and with the "back-end" data base.  Especially for various Top-Level Domains, the desire is to permit multiple registrars to share access to the database.  This BOF will consider a working group for development of a protocol for a registrar access to the registry.  The protocol will permit interaction between a registrar's own application and the data base service running a domain name service registry repository. Specification for user interface access, such as by a web front end, is beyond the scope of the proposed working group.  The working group will base its efforts on the CORE SRS version 1.5 protocol, as documented in .
