1.  Introduction

   This document describes the usage of HTTP for Registration Data
   Directory Services.  The goal of this document is to tie together
   usage patterns of HTTP into a common profile applicable to the
   various types of Directory Services serving Registration Data using
   RESTful practices.  By giving the various Directory Services common
   behavior, a single client is better able to retrieve data from
   Directory Services adhering to this behavior.
