- Summary
-
- Draft 3.0 of POSIX.17 completed the first round of IEEE balloting in
- May. We met primarily as a ballot resolution team in Chicago,
- resolving 98% of all outstanding comments and objections. Since the
- Chicago meeting, we have finished Draft 3.0 ballot resolution, and
- published and re-circulated Draft 4.0 for ballot. We plan to get the
- ballot results in time to resolve comments at the Utrecht meeting in
- October. From there we plan to submit the balloted specification to
- the IEEE for final approval, publication and forwarding to ISO for
- fast tracking (i.e. direct ISO ballot).
-
- Our Project Authorization Request (PAR) has been split/recast into 4
- separate PARs to:
-
- 1. separate the Directory Services API work (which is almost
- finished) from the POSIX name space issue which hasn't received
- much attention, and
-
- 2. separate the actual document into a format aligned with ISO
- expectations.
-
- Introduction
-
- The POSIX.17 group has generated and is currently balloting a user to
- directory services API (e.g. API to an X.500 DUA - Directory User
- Agent). We used APIA - X/Open's XDS specification as a basis for work.
- XDS is included in XPG4 and has been adopted as part of both OSF's
- Distributed Computer Environment (DCE) and Unix International's Atlas.
-
- XDS is an object oriented interface and requires a companion
- specification (XOM) for object management. XOM is a stand- alone
- specification with general applicability beyond the API to directory
- services. It will be used by IEEE P1224.1 (X.400 API) and possibly
- other POSIX groups, and is being standardized by POSIX/TCOS as P1224.
- A draft of P1224 is already in ballot.
-
- Status
-
- POSIX.17 was reviewed by the Project Management Committee for the
- Chicago meeting without problem.
-
- Draft 3.0 of POSIX.17, which included all test methods and its
- Language Independent Specification (LIS), completed IEEE ballot prior
- to the Chicago. The group spent a majority of the meeting processing
- the results of that ballot. Over 200 comments/objections were
- processed, with all but 4 tentatively resolved. Actions were assigned
- to resolve the remaining four. Our technical editor did an incredible
- job in producing Draft 4.0 in time for a recirculation ballot, which
- closed October 5th.
-
- POSIX.17 was one of three TCOS-SS projects recommended for fast track
- ballot to ISO during a special ad hoc meeting of the US TAG to JTC1.
- [Ed. - ISO is responsible for developing and approving of
- international standards. TCOS-SS (Technical Committee on Operating
- Systems - Standards Subcommittee) is the IEEE committee responsible for
- developing operating system standards, e.g. POSIX. Documents
- developed by the IEEE can be forwarded by an ANSI (hence U.S.)
- Technical Advisory Group (TAG) to the Joint Technical Committee (JTC1)
- of ISO and the International Electrotechnical Committee (IEC) for
- consideration as ISO standards.]
-
- In order to accommodate the ISO format, POSIX.17 needed to be split
- into 4 separate parts (documents). To that end, four PARs were
- submitted to the IEEE which requires a PAR for every document. This in
- effect revises our current work to reflect the ISO format
- requirements. These have been reviewed and accepted by the IEEE Review
- Committee (REVCOM) and assigned the following project numbers under
- the general heading of "OSI APIs".
-
- P1224.2 - Directory Services API - Language Independent
- specification
-
- P1326.2 - Test Methods for P1224.2
-
- P1327.2 - C Language Binding for P1224.2
-
- P1328.2 - Test Methods for P1327.2
-
- My understanding is that when P1224.2 and P1327.2 are approved by the
- IEEE, they will be proposed to ISO as Draft International Standards
- (DIS).
-
- In Closing ...
-
- The group is meeting in Utrecht in October, where we plan to process
- the results of our September recirculation ballot. If all goes to
- plan, we will submit our specification to the IEEE for acceptance as a
- standard before year's end. Based on this schedule, I would expect to
- see it published by the IEEE in the first half of 1993.
