I have noticed several recent authors who still cite old versions of
CGIF (e.g., John Sowa's 2000 version). Some of these refer to dpANS,
cgdpansw.htm, and so on. I wanted to clarify their status very simply:
They have no official standing! In general they should be removed from
all web pages and future papers; they should under no circumstances be
referred to as "standard" anything.
There is no such thing as a "draft international standard" for
archival citation purposes, since drafts may change substantially
before final approval (and they often do). There is no ANSI (i.e.,
United States) standard for CGIF and there never has been. (If anyone
wants to volunteer to propose the ISO/IEC standard as an ANSI
standard, please step forward.) I am not aware of any other country's
standardization of CGIF either. Use of the word "standard" with CGIF
has only one meaning at present; namely, Annex B of --
ISO/IEC, “ISO/IEC 24707:2007 - Information technology - Common Logic
(CL) - A framework for a family of logic-based languages,” 2007;
http://standards.iso.org/ittf/PubliclyAvailableStandards/c039175_ISO_IEC_24707_2007(E).zip
.
Having spent several years and a great deal of effort to establish a
single CGIF standard under Common Logic, I want to encourage readers
of this list to USE IT! Though it is similar to previous versions,
there are differences which you will see when you read Annex B of the
standard.
ISO/IEC 24707:2007 -- The real thing. Accept no substitutes.

Harry
