1. Introduction

The North American Directory Forum (NADF) is a collection of service

providers which plans to cooperatively offer a Public Directory

Service in North America using the CCITT X.500 Recommendations.

Although many groups are working on realizing X.500, the NADF is

unique in that it must achieve a cooperative service offered by

competing providers.

The purpose of this document is to provide a brief overview of the

NADF's Standing Document series. As of this writing, the standing

documents are:

and Its Application for c=CA and c=US

SD-6 Guidelines on Naming and Subtrees

SD-12 Registry of ADDMD Names

SD-13 NADF Accounting and Settlements

SD-1 defines the scope of the NADF, whilst SD-2 describes issue of

interest to the NADF.

The remaining documents describe the agreements necessary to achieve

a cooperative Public Directory Service offered by competing

providers. In this context, it should be observed that the NADF

relies on X.500(88) to the largest extent possible.

SD-3 contains agreements concerning the Directory "service", e.g.,

quality of service, whilst SD-4 contains agreements concerning the

Directory schema.

SD-5 concerns itself with how a national authority should structure

its DIT subtree, and then applies these principles to define the

naming scheme for the c=CA and c=US parts of the DIT. The NADF's

approach is to divide a national DIT subtree into two portions: the

public name-space, which corresponds to information objects having

some sort of public recognition (e.g., states, counties, businesses,

etc.), and several private name-spaces, each unilaterally managed by

a public provider of Directory services. (SD-12 defines the registry

of these providers.) Based on the civil standing of an entity, that

entity may opt to list as one or more entries in the public name-

space. That is, registration, per se, occurs outside of the

Directory. This is an important concept as it allows an entity to

list where others are likely to search.

SD-6 provides guidelines as to how organizations might wish to

organize their private name-space, and also discusses how multi-

nationals might choose to list themselves.

SD-7 contains agreements concerning how the DIT is mapped onto

multiple DMDs. Knowledge maintenance procedures are absent from

X.500(88), and products which support X.500(92) are years away.

Further, the competitive relationships between the North American

Directory providers invalidate any possibility of a single entity

having exclusive management rights to the public name-space. The

NADF approach is to cooperatively manage the public name-space by

allowing each service provider to provide linkage from the public

name-space into their own private name-space. This information is

limited to knowledge references and naming links; there is little, if

any, payload present. SD-9 discusses how a central authority (termed

the CAN) coordinates and disseminates this information. In effect,

the CAN publishes a roadmap for North American Public Directory

Service.

SD-8 describes agreements reached for the NADF Pilot.

SD-10 describes the NADF policy toward security and privacy.

Attachment 1 of SD-10 contains the "User Bill of Rights for entries

and listings in the Public Directory". In contrast, SD-11 describes

the security facilities available in the Directory, and then

specifies which mechanisms which will be used in the Public Directory

service.

SD-12 provides a registry of ADDMD names in the NADF project.

SD-13 provides a model and general principles for accounting and

settlement in the directory.

1.1. Document Availability

At the present time, the NADF standing documents are available only

in hardcopy and PostScript form. Since they do not exist in ASCII
