Abstract

   This document describes an application layer client-server protocol
   for the provisioning and management of objects stored in a shared
   central repository.  Specified in XML, the protocol defines generic
   object management operations and an extensible framework that maps
   protocol operations to objects.  This document includes a protocol
   specification, an object mapping template, and an XML media type
   registration.

1.  Introduction

   This document describes specifications for the Extensible
   Provisioning Protocol (EPP) version 1.0, an XML text protocol that
   permits multiple service providers to perform object provisioning
   operations using a shared central object repository.  EPP is
   specified using the Extensible Markup Language (XML) 1.0 as described
   in [XML] and XML Schema notation as described in [XMLS-1] and [XMLS-
