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 [email protected]>.
