- U.S. TAG to ISO/IEC/JTC1/SC22 WG15
-
- Susanne Smith <sws@calvin.wa.com> reports on the July 19, 1990 meeting
- in Danvers, MA:
-
- 1. Overview
-
- Before you ask, ISO/IEC JTC1 SC22 WG15 is ISO POSIX. The U.S. TAG is
- the United States Technical Advisory Group, which formulates the U.S.
- position on WG15 issues, and chooses the members of the U.S.
- delegation to the international WG15 meetings.
-
- This meeting began at 8:00 A.M. and ended before noon. This must be
- a record -- not just for the TAG, but for any standards group meeting.
- There were three major business items:
-
- - language independence,
-
- - document circulation procedures (yawn), and
-
- - rapporteurs.
-
- This short agenda, coupled with a determination to avoid an extra
- meeting, like the Denver meeting we were forced into in June, kept the
- discussion on track all morning.
-
- ISO POSIX: Winners and Losers
-
- The vote for 9945-1.2 (1003.1a draft 5) was unanimously in favor
- without substantive comments. If all goes well there just may be an
- IEEE version of 9945-1 available in Seattle. Let's all cross our
- fingers. Now that it's September I think we need to cross our toes as
- well.
-
- My last report mentioned the formatting problems with the 9945-1
- document. The TAG had decided to request the formation of an ad hoc
- committee in Paris to try to resolve these problems. WG15 resolved to
-
- __________

- * UNIXTM is a Registered Trademark of UNIX System Laboratories in
- the United States and other countries.

- instruct the WG15 convener, Jim Isaak, to request written editorial
- requirements from the ITTF (formerly the Central Secretariat) and
- IEEE, and forward these to SC22. The emphasis here should be on
- written requirements.
-
- WG15 refused to register 1003.4, real-time extensions, as a CD
- (committee document, formerly DP, draft proposal) because it is not a
- language-independent specification. They were also concerned that the
- standard might have to change once there is a language independent
- version of 1003.1.
-
- 1003.5, Ada binding, and 1003.9, FORTRAN binding, suffered a similar
- fate for different reasons. 1003.5 and 1003.9 were held off until at
- least the October WG15 meeting because G15 had not seen the 1003.5 and
- 1003.9 documents, and were reluctant to register something they hadn't
- seen before. And again, they were concerned that these standards
- might have to be re-written once there is a language independent
- version of 1003.1.
-
- Administrivia
-
- Skip to the next section if you're easily bored or just not interested
- in bureaucracy.
-
- Why, you ask, was WG15 being asked to register something they had not
- seen before? Here are the steps that have to complete before a
- document gets circulated:
-
- 1. The committee and SEC approve its release.
-
- 2. The TAG approves its circulation.
-
- 3. The committee chair delivers the document to the TAG chair, Donn
- Terry.
-
- 4. The TAG chair forwards the document to the WG15 convener, Jim
- Isaak.
-
- 5. The WG15 convener distributes the document.
-
- 1003.5 and 1003.9 were approved by the TAG for circulation to WG15
- during the April meeting in Snowbird. This left six weeks for for the
- documents to be circulated and read. The problem was that the TAG
- chair did not receive the documents in time to have them circulated
- before the meeting. To avoid this problem in the future, the TAG is
- going to ask the SEC to assign an action item to the committee chair
- so that there is a method to track this task.

- Are You Ready for UNIX in VDM?
-
- We cannot delay language independence for 1003.1 any longer. It's now
- really holding up international progress on important POSIX efforts.
- But what format or technique should we use? ISO rules seem to require
- an ISO-standard method, which could restrict us to VDM (Vienna
- Definition Method), but no one thinks VDM will work. Paul Rabin and
- Steve Walli have been working on a method, but the TAG worries that a
- non-standard method will create problems like those we've suffered
- through with document formats (see last TAG report). In order to
- avoid rejection later we will circulate the new method in SC22 and
- WG15 for review and comment. To make this circulation useful, Donn
- Terry is listing specific questions for SC22 and WG15 to answer.
- [Editor: I believe that ISO rules only restrict us to VDM if we
- produce a formal definition, i.e., something from which one could do
- correctness proofs. Of course, rules and politics are not always the
- same thing and using VDM might help grease the skids. Still, we
- should stop and ask if not using VDM would hold us up any more than
- using VDM.]
-
- The TAG will also ask the WG15 convener to schedule an ad hoc meeting
- on language independence, during the October WG15 meeting, to help
- move it along.
-
- ``Rap, a-rap, a-rap, they call me the rapporteur.''
-
- Rapporteurs are technical experts on specialized aspects of a
- particular standards effort. Their scope is usually broader than an
- individual standard, and they usually coordinate efforts in several
- standards bodies. WG15 has three rapporteur groups, one each for
- conformance, internationalization, and security. We send a
- representative to each.
-
- The conformance-testing rapporteur group will be looking at 1003.3
- draft 12 (conformance testing), and the OSF-UI-X/Open Phoenix project
- as potential base documents for the ISO 9945-series documents. The
- Phoenix project is developing a conformance-testing platform. We will
- not have to decide whether we want to submit 1003.3 as a new work item
- in this area until 1991.
-
- Ralph Barker asked that UniForum be allowed to send him and one
- UniForum Internationalization Technical Committee member to the next
- internationalization rapporteur group meeting. This person would be
- subject to subcommittee approval but selected by UniForum. Worry

-
- about the fact that the TAG would not choose this person evaporated
- when it became clear that Donn Terry would continue as
- internationalization rapporteur and that the UniForum members would
- just be an addition.
-
- The TAG appointed Al Weaver security rapporteur to fill the vacancy
- Terry Dowling left when he resigned in January.
-
- Summary
-
- The most important development is that the synchronization proposal
- discussed in the last report is already dead. This proposal was to
- have fed balloting responses from IEEE into WG15, and vice-versa,
- allowing WG15 approval to follow on the heels of IEEE approval. Now,
- while the IEEE is advancing, everything in WG15 is blocked by 1003.1
- language independence.
