Abstract

This document defines a representation of the O/R Address hierarchy in the Directory Information Tree [6, 1]. This is useful for a range of purposes, including:

o Support for MHS Routing [4].

o Support for X.400/RFC 822 address mappings [2, 5].

Table 1: Order of O/R Address Directory Components

1 The O/R Address Hierarchy

An O/R Address hierarchy is represented in the X.500 directory by associating directory name components with O/R Address components. An example of this is given in Figure 1. The object classes and attributes required to support this representation are defined in Figure 2. The schema, which defines the hierarchy in which these objects are represented in the directory information tree is specified in Table 1. A given object class defined in the table will always be higher in the DIT than an object class defined lower down the table. Valid combinations of O/R Address components are defined in X.400.
