Abstract

   A single, unified, global whitepages directory service remains
   elusive.  Nonetheless, there is increasing call for participation of
   widely-dispersed directory servers (i.e., across multiple
   organizations) in large-scale directory services.  These services
   range from national whitepages services, to multi-national indexes of
   WWW resources, and beyond.  Drawing from experiences with the TISDAG
   (Technical Infrastructure for Swedish Directory Access Gateways)
   ([TISDAG]) project, this document outlines an approach to providing
   the necessary infrastructure for integrating such widely-scattered
   servers into a single service, rather than attempting to mandate a
   single protocol and schema set for all participating servers to use.

1. Introduction

   The TISDAG project addressed the issue of providing centralized
   access to distributed information for whitepages information on a
   national scale.  The specification of the eventual system is
   presented in [TISDAG], and [DAGEXP] outlines some of the practical
   experience already gained in implementing a system of this scale and
   nature.  [DAG-Mesh] considers the issues and possibilities of
   networking multiple DAG services.  Following on from those, this
   document attempts to describe some of the architectural underpinnings
   of the system, and propose directions in which the approach can be
   generalized, within the bounds of applicability.
