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:NADF                                                            [Page 1]

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.NADF                                                            [Page 2]

RFC 1417                NADF Standing Documents            February 1993   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.1.1.1.
