Subject: Re: UDEF's day in the sun


Thank-you for the note to the group and for including the pointer from
your home page. As noted in past regrep meetings, I believe that a UDEF
based naming convention that conforms to ISO/IEC 11179 and that uses the
property terms (class words) of DoD 8320.1-M-1 is a necessary part of
the global registry and repository. The article by Bill Lewis does an
excellent job of highlighting the fact that XML needs an answer to the
semantic dispersion problem. Until a solution is widely adopted, the
various XML dialects will continue to generate applications that are
designed for computer-to-human-to-computer integration.

A joint AIA/EIA/DoD effort to create a National standard for Data
Interoperability and Configuration Management (EIA 836) is planning to
include the UDEF naming convention as part of the standard. The EIA 836
announcement is at:
