PROGRESS AND STATUS OF WG11 PROJECTS
Part 11 Edition 2 - status
Reporting - Jochen Haenisch
No meeting
Under the new SC4 cancellation policy, P11e2 is scheduled to
be cancelled in the fall if it is not published.
The Secretariat is still waiting for final document from
before sending to Geneva. About 20 editorial problems that
were discovered since FDIS still need to be fixed.
Phil promises to produce new document by end of week, but
needs definitions for PRIMARY and ROOT schema. Jochen will
work on this with possible help from Allison & PW.
Send to Geneva by 2004-08-01
As a result of E2 to E1 testing, EXPRESS E2 Short to E1 Long
Implementer Agreements have been published as wg11n239. This
appears to be the final form of these agreements.
Need to begin TC for language identifier and to fold in the
contents of the implementer agreements above (rule for
handling of referenced entity data types to constraing to
dependant instantiation -- missing type label for local
declaration of generics within functions) The TC should also
address SEDS #915, submitted by Lothar Klein, if needed.
Allison volunteered to reformat the implementer aggrements
into the Technical Corrigendum format. We need additional
volunteers for the TC team to develop text for the remaining
two issues (lang id and SEDS 915). Dave L will circulate a
request for participation on the WG11 exploder after the
meeting and specifically requests participation from Jochen
Haenish and Phil Spiby.
Phil wishes to resign as Project Lead once the document is
published.
Part 12 - published 1997-07-15
Has gone through two reviews. We must now
- Issue as a TR type 3
- Progress to IS
- Withdraw
Either of the first two will require editorial changes to
the document for the new supplemental directives and at least
new copyright dates, page headers/footers. Complicating this
situation, the original author has just retired. Unknown if we
still have original LaTex source.
The last one (withdraw) may cause problems with the few ATS's
that have been published.
There is some interest in keeping this. Call for editor.
Part 14 - status 40.60
Reporting -- Peter Denno (via Dave Loffredo)
No meeting
DIS ballot ran from 2002-04-02 to 2002-10-25
Passed with 100% approval, so no FDIS needed.
Under the new SC4 cancellation policy, P14 is scheduled to
be cancelled in the fall if it is not published.
Document has been updated and is currently beeing reviewed
for the signoff checklists. When complete, circulate updated
document for a 4-week wg11 review before sending to ISO for
publication. Begin review by 2004-09-01 and send to Geneva
by 2004-09-01.

Part 25 - status 30.92
Reporting -- David Price
Met 2004-07-06, 10:30-12
Unanimously passed second TS ballot (see sc4n1584)
Comments addressed, document 2/3 updated.
Reached agreement on resolution of all comments. Accepted
almost every change. Deferred part of one comment that was
the same as the "lean mapping".
Will prepare new document for publication, anticipate ready in
one month or so. Will circulate for 4-week wg11 review before
sending to ISO for publication.
There have been implementation tests of the edition one
specification by the IAI IFC team and by David Price. There
is now enough coverage in the (standard? impl?) to publish ISO
15926-2 as UML (see exff.org). Edition one is also being used
in the recently adopted OMG PLM Services Specification.
In discussing a NWI for Edition 2, the project notes that E1
is one-way EXPRESS Edition 1 to UML 1.5 designed to support
STEP implementation using UML-based software engineering
tools. The resulting UML is not tagged as being from EXPRESS.
The proposed second edition will remain based on UML 1.5, and
will extend the current mapping to cover EXPRESS E2. It will
also add a new capability to represent EXPRESS E2 constructs
annotated as EXPRESS (a UML Profile for EXPRESS) and extend
use of Object Constraint Language where straightforward.
(Not expecting to include complete support for all of EXPRESS
expressions)
The following usage scenarios are expected for the Part 25
Edition 2:
- continued support of P25e1 usage : STEP implementation
using UML-based software engineering tools
- support EXPRESS and UML constructs on the same UML diagram
- enable the use of UML tools to create EXPRESS schemas in a
manner similar to the way EXPRESS-G tools are used today
- enable the use of UML in the specification of a complete
software system that includes EXPRESS constructs and the use
of EXPRESS in the context of the OMG Model Driven Architecture
Technical approach expectations
UML Stereotypes and Tagged Values, not extensions to UML
itself, will be used to define this aspect of P25e2
UML 2 and MOF 2 are not yet finalized or commercially
available in UML tools so, Part 25 Edition 2 is focused
on UML 1.5.
Suggesting Part 25 Edition 3 will be required to address UML2
and MOF 2 in 2005
Part 26 - No report, cancelled
Part 27 - No report, published 2000-11-15
Part 28e1 - No report, published
Part 28e2 -
No Report
Joint Meeting 2004-07-07, 3:30-5
The Part 28e2 document is out for CD ballot until 2004-07-21.
See sc4n1711 for details. A comment resolution workshop will
be held in Groton CT on August 10-12
A joint WG3/WG11/implementers forum meeting was held to
discuss on use requirements for XML / Part 28e2. Outline of
use cases from interested AP teams and the Part 28 team.
During the discussion, several levels of use were identified:
- "Simple" mapping to XML, defined by APs
- Mapping to XML with validation capabilities
- Fully-configurable mapping
These requirements are to be documented in comments on the CD
ballot. The Groton workshop will focus on simple case first,
with possible division of document for publication. Need to
assure cross-enterprise consistency. The definition of
"simple" is still being refined
Teleconferences will be held on 2004-07-16 and 2004-07-30 to
prepare.

NEW BUSINESS
EXPRESS-Based Binary Data Exchange ------------------------------
Met 2004-07-06, 1-5pm
Mats Lindeblad and David Price held a meeting on Tuesday to discuss
work on starting a new WG11 project for binary exchange of
EXPRESS-defined data. Prior to the Bath meeting, David Price
circulated the following documents for requirements and potential
implementation Technologies:
wg11n240 Requirements on EXPRESS Binary Data Representations
wg11n241 A Survey of the State-of-the-Art in Binary Data Representation
At the moment no standardized mapping from EXPRESS to binary exists
and there is a percieved industry need for an efficient, binary form
to represent EXPRESS-compatible data. Note that this form would
complement to ISO10303-21/28 and be useful fo Engineering Analysis,
Manufacturing, Measurements and more.
Participants representing Sweden, UK, US, Japan, Germany, and France
have expressed support and the EU 6th FP project "VIVACE" has funcing
for a Project Lead and Editor 2004-2007.
During the week, Mats presented the above to change management in
support of a PWI with the eventual goal of a new 20-series project
within SC4/WG11 and the following milestones:
- Jul 2004: PWI as SC4 Letter Ballot
- Sep 2004: Release analysis of potential candidate technologies
- Oct 2004 (Seattle SC4 meeting): Decide on scope & candidate
technologies to include in CD document
- Nov 2004: Release of technically complete CD document for review
- Feb 2005: Submit for CD balloting
- Mar 2005 (Lillehammer SC4 meeting): Hold walk through for ISO/SC4
community
- Jul 2005 (Spain SC4 meeting): Hold CD ballot resolution workshop
- Sep 2005: Publish ISO TS document
The project would then continue to progress the document towards IS
with the eventual goal:
- Nov 2007: Published ISO International Standard of document(s)
EXPRESS/STEP and OWL ------------------------------
Meeting 2004-07-08, 8-12
Will produce a W3C note to discuss the relationship between
OWL and EXPRESS.
