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.

Please send comments to the author or to the discussion group <osi- ds@CS.UCL.AC.UK>.

1. Overview

The purpose of this document is to define some metrics by which DUA products can be measured. It should be first be noted that the use of the term "DUA" is rather misleading. There is an assumption here that the DUA is implemented correctly and is able to "talk" valid X.500 protocol: this is a sine qua non. Instead, this document see...
