- 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-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.
-
- 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.
