Abstract

This RFC is being distributed to members of the Internet community in

order to solicit their reactions to the proposals contained in it.

While the issues discussed may not be directly relevant to the

research problems of the Internet, they may be interesting to a

number of researchers and implementers.

This document defines a set of criteria by which a DUA

implementation, or more precisely a Directory user interface, may be

judged. Particular issues covered include terminal requirements;

style of interface; target user; default object classes and attribute

types; use of DAP; error handling. The focus of the note is on

"white pages" DUAs: this is a reflection of the current information

base. Nevertheless much of the document will be applicable to DUAs

developed for other types of Directory usage.
