Kevin Lewis <klewis@gucci.dco.dec.com> reports on the April 23-27
meeting in Salt Lake City, UT:
Where we are
The Utah meeting of the IEEE 1003.0 working group marks the beginning
of its third year. Let's step back for a moment to review the past
two. We have gone from scratch to a 180-page document, whose content
represents about 70% of the content goal that we set for our work two
years ago. (More on this in a moment.)
This effort represents the contributions of a core group of 15 to 18
people. In 1988, 14 vendor organizations and 16 user organizations
were represented within the group. Today, we have nine vendor
organizations and 16 user organizations represented. Of course, the
only official, formal organizational representatives allowed within
IEEE working groups are accredited, institutional representatives
(currently Usenix, UniForum, X/Open, Unix International, and the Open
Software Foundation each supply one to the POSIX effort), but that
does not stop me from checking the sign-up sheet whenever a new face
shows up, to see where he or she works. For example, I think someone
from the Univ. of Berkeley involved in BSD UNIX development has a
vendor's perspective, while I place attendees from NIST and the Air
Force in the user category because I believe they focus on the
interests of their own end users. Our stable, steady user
representation is essential: our ultimate targets are users trying to
walk through the POSIX maze.
The 70% completion of our initial content goal includes the
introduction of the ``profile'' concept, which has led to increased
activity within the IEEE TCOS Standards Subcommittee to create groups
to define profiles (which may be good or bad depending on your own
prism). The concept of profiles is also part of the US's contribution
to the ISO community, made through its participation in the JTC1
Technical Study Group on Application Portability (JTAP), within which
the ``profiles'' concept has now garnered wide acceptance.

``What is a profile?'' you ask. Users seeking open system solutions
need to know what parts of the open system environment (OSE) address
their requirements. If a user could reach into the full basket of OSE
parts and pull out only those he specifically needs, those selected
parts would be his application environment profile. What he should do
if he needs something not in the basket? Come to our next meeting
with a recommendation. [Editor: Or drop Kevin a line, or post
something to comp.std.unix!]
Where we're going
Dot Zero still faces hard decisions in two areas:
1. the necessity or desirability of parts of our guide. (Two parts
that I very much think are candidates for this discussion are
User Interface and Security)
2. The final bounds of the profile concept/definition.
The group's arguments in these areas are not frivolous, but if they
continue much longer, the resulting lack of movement will hurt our
overall effort.
I came out of this meeting feeling that everyone is committed to
getting over these hurdles soon (i.e., by the July meeting). Our
chair, Al Hankinson, has also stated that we should target December,
1990 for a mock ballot. I wholeheartedly agree. This will add the
impetus that we need. Let's see if we have the self-discipline to get
there.
