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.
