Writing X.400 O/R Names

Status of this Memo

This memo provides information for the Internet Community. It does

not specify an Internet Standard of any kind. Distribution of this

memo is unlimited.

1. Introduction

There is a need for human beings who use X.400 systems to be able to

write down O/R names in a uniform way.

There has been a preexisting recommendation on how to write O/R names

for human consumption in the RARE community. Now that the ISO/ITU has

adopted a recommendation on how to do this [1], RARE needs to update

its recommendation on writing O/R names to take this standard into


2. Recommendations on writing O/R names

RARE recommends that the ISO standard be followed when writing O/R

names. The ISO/ITU standard contains a number of options. RARE makes

the following recommendations:

- The "main" abbreviations, G, I, S, O, OU1, OU2, P, A and C

are used. They should be written using UPPER CASE.

- The separation character should be semicolon (;).

- The ADMD value "blank" is expressed by omitting the

attribute. No other interpretation of a missing ADMD

attribute is allowed.

- The recommended sequence is G=;I=;S=;O=;OU1=;OU2=;P=;A=;C=;

This means that the O, OU1 and so on will be in opposite order to the

fields of an Internet domain name; the reason for choosing the

ISO/ITU order is that this will be more common among users of X.400

Representation of O/R addresses for human usage (This annex does

not form an integral part of this Recommendation|International


F.1 Purpose

An O/R address (specified in clause 18) consists of a set of

values of attributes taken from the list shown in Table F.1. In

order to represent visually an address to a human user, and to

enable the user to enter the address into a user interface, each

attribute value needs to be associated with the correct attribute

type. Many of the names of the attribute types shown in Table F.1

are too long for convenient usage on paper or ...
