Abstract

   This document describes an Extensible Provisioning Protocol (EPP)
   mapping for the provisioning and management of Internet domain names
   stored in a shared central repository.  Specified in XML, the mapping
   defines EPP command syntax and semantics as applied to domain names.
   This document obsoletes RFC 3731.

1.  Introduction

   This document describes an Internet domain name mapping for version
   1.0 of the Extensible Provisioning Protocol (EPP).  This mapping is
   specified using the Extensible Markup Language (XML) 1.0 as described
   in [W3C.REC-xml-20040204] and XML Schema notation as described in
   [W3C.REC-xmlschema-1-20041028] and [W3C.REC-xmlschema-2-20041028].
   This document obsoletes RFC 3731 [RFC3731].

   [RFC4930] provides a complete description of EPP command and response
   structures.  A thorough understanding of the base protocol
   specification is necessary to understand the mapping described in
   this document.

   XML is case sensitive.  Unless stated otherwise, XML specifications
   and examples provided in this document MUST be interpreted in the
   character case presented to develop a conforming implementation.

1.1.  Relationship of Domain Objects and Host Objects

   The EPP mapping for host objects is described in [RFC4932].  This
   document assumes that domain name objects have a superordinate
   relationship to subordinate host name objects.  For example, domain
   name "example.com" has a superordinate relationship to host name
   "ns1.example.com".  EPP actions (such as object transfers) that do
