Abstract

The X.500 directory provides a powerful mechanism for storing and retrieving information about objects of interest. To interpret the information stored in the directory, the schema must be known to all the components of the directory. Presently, there are no means other than ftp to distribute schema information across the Internet. This is proving to be a severe constraint as the Directory is growing. This document presents a solution to the schema distribution problem using the existing mechanisms of the directory. A naming scheme for naming schema objects and a meta-schema for storing schema objects is presented. The procedures for fetching unknown schema from the directory at runtime are described.

Abstract

The X.500 directory provides a powerful mechanism for storing and

retrieving information about objects of interest. To interpret the

information stored in the directory, the schema must be known to all

the components of the directory. Presently, there are no means other

than ftp to distribute schema information across the Internet. This

is proving to be a severe constraint as the Directory is growing.

This document presents a solution to the schema distribution problem

using the existing mechanisms of the directory. A naming scheme for

naming schema objects and a meta-schema for storing schema objects is

presented. The procedures for fetching unknown schema from the

directory at runtime are described.

1. Introduction

The X.500 Directory [1] is now used for a wide range of applications

from name/address lookup to network management, from restaurant

information to bibliographic information services. This information

is distributed and managed across a network of many autonomous sites.

In order to interpret the information stored in the directory, the

components of the directory must have knowledge about the structure

and representation (sc...
