+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:

+ SD-0 NADF Standing Documents: A Brief Overview
+ SD-1 Terms of Reference
+ SD-2 Program Plan
+ SD-3 Service Description
+ SD-4 The Directory Schema
+ SD-5 An X.500 Naming Scheme for National DIT Subtrees
+ and Its Application for c=CA and c=US
+ SD-6 Guidelines on Naming and Subtrees
+ SD-7 Mapping the North American DIT
+ onto Directory Management Domains
+ SD-8 The Experimental Pilot Plan
+ SD-9 Charter, Procedures and Operations of the
+ Central Administration for NADF
+ SD-10 Security & Privacy: Policy & Services
+ SD-11 Directory Security: Mechanisms and Practicality
+ 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
+ form, the NADF standing documents can not be distributed as
+ informational RFCs. Following are the various distribution
+ mechanisms available.
