===== General

The final version of the Member Agreement will be mailed to CIW members
in the near future.  Please sign and return two copies.

X/Open will be considering the adoption of CPI-C 2.0 and publication of
an X/Open CPI-C Preliminary Spec in 94.  X/Open CPI-C would be based on
the AP/CP version of the CPI-C Spec approved at the December93 CIW
meeting.  Both the CIW and X/Open want to ensure that X/Open CPI-C is the
same as the CPI-C 2.0 approved by the CIW.

Marilyn Gallagher, CIW Editor, presented the schedule for the next
draft of the CPI-C 2.0 Spec based on the December93 CIW action.
It will be available 12/9/93 in the document library for review.
Comments are due by 12/13/93.  The new reference draft will be
available on 12/16/93 in the document library (and to X/Open)
and will be used for page numbers and current text when requesting
changes to the architecture.

Questions about the documentation should be addressed to
[email-masked].

The announcement by the CIW of the completion of the definition CPI-C 2.0
is being planned for March, 94, just after the March CIW meeting, where
CP status is anticipated on the CPIC 2.0 enhancements.  A number of CIW
member companies will be participating.  If you want to be included,
contact Anne Schick (919-254-4219, [email-masked]) for information.

===== SIG meeting reports

Productive SIG working meetings were held on the topics listed below.  A
brief summary of each SIG working meeting is included.  A more complete
account of each SIG meeting will be distributed to the SIG via e-mail.

  Full Duplex
    The Full-Duplex SIG reviewed the Closed Pages proposal, which was
    available in the document library as file ciwfdxcp.ps, dated
    Nov 16, 1993.  The SIG also reviewed a few other changes that were
    proposed after November 16. The contents of the proposal were
    approved by the SIG.  Closed Pages status was granted to the
    full-duplex CPI-C architecture in the plenary session of the CIW
    on Friday, December 3.

  Non-blocking
    The NB SIG reviewed three amendments to the CP document:
    system-dependent usage notes for the Set_Queue_Callback_Function
    call, an example of using queue-level non-blocking, and a usability
    enhancement to the Wait_For_Completion call.  The proposed changes
    were granted Closed Pages (as amended) status during the closing
    plenary.

  Extensions for OSI TP
    The OSI TP SIG discussed several minor editorial corrections related
    to the OSI TP enhancements in the October draft. The closing plenary
    granted Closed Pages status to the OSI TP enhancements.

  Directory
    The directory SIG reviewed the latest document draft (distributed
    11/5).  Additions agreed to include:  new directory_syntax and
    directory_encoding parameters, new values for the partner_ID_type
    parameter, and further definition of CNSI objects.  See the
    directory SIG meeting minutes for complete details of the discussion.
    The proposal was granted AP status at the closing plenary.

  Security
    The SIG reviewed and approved change pages for Distributed
    Security and for OSI-TP support.  The changes are available
    in file /ciw/sig/sec/secpages.ps.  Approved Pages status
    was then granted by the CIW in the closing plenary.

  Secondary Return Codes
    The 2RC SIG reviewed a change pages proposal based on the AD
    document approved by the CIW on 11/2/93.  The proposal was
    largely agreed to by the SIG with two additions: describing
    the use of a separator when the condition code is absent and
    including a note to implementers about maintaining secondary
    information.  The revised proposal was granted Approved Pages
    status during the closing plenary.

  Conformance for CPI-C Level 2
    The Conformance SIG considered a proposed definition of CPI-C 2.0
    mandatory and optional support groups and reached agreement
    on the proposal with minor modifications.  A proposal from Siemens
    to define mandatory support as the CPI-C Starter Set was not
    accepted.  A proposal to include an appendix to the CPI-C Spec
    that describes how an X/Open program can migrate to CPI-C 2.0 was
    accepted.  The SIG approved the addition of two new
    return codes to indicate the lack of support for optional function,
    this change to go in as an ammendment to the AP-level Spec.
    The closing plenary session approved the action of the SIG.
    Based on the consensus in favor of the conformance classes
    proposal, the SIG will aim at interim AP approval before the
    March CIW meeting and for CP at the March.  Additional details on
    the SIG meeting will be reported in the Conformance SIG minutes.

  Automatic Data Conversion
    Jeff Hildebrand led technical discussions based on his contribution.
    Points under discussion included requirements, terminology,
    support in the underlying CPI-C/system/CRM layers, and how to
    set and extract a map name for a data record.
    At the closing plenary, the CIW granted AD status on the call syntax,
    with more work needed on requirements, background, etc.
    Jeff indicated his intention to push for interim AP status and
    for CP in March.

===== New Business: Specify Local Address

The CIW accepted a new work item to address requirements for a program
to specify the local LU through which it will receive support.  A
new SIG (Specify Local Address) has been created to work on the item.
Wall Data will be developing a proposal for consideration in March 94.
