Subject:  NIST ODA SIG Update

The National Institute of Standards and Technology (NIST) hosts quarterly
meeting of the OSI Implementors Workshop (OIW).  The Workshop is
segmented into Special Interest Groups (SIG) for each of an OSI related
set of standards.  Implementation agreements for the ISO 8613, Open
Document Architecture (ODA) and Interchange Format, base standard are
addressed by the ODA SIG.  These agreements take the form of
document application profiles (DAP), as defined in part 1 of the base
standard.  The NIST OIW maintains two sets of implementation
agreements.  The developing agreements are maintained as OIW Working
Agreements.  The completed agreements are maintained as OIW Stable
Agreements.  The Stable Agreements are often found to be the basis for
Government OSI Profile statements.

The ODA SIG is involved in the development and international
harmonization of three ODA DAPs.  The NIST Level 2 DAP (NIST36) is
intended to address the ODA requirements for advanced word processors
supporting enhanced document structure with mixed content.  The NIST
Level 3 DAP (NIST26) is intended to address the ODA requirements for
personal publishing applications supporting extended document structure
with mixed content.  The NIST Raster DAP is based on the CCITT
Recommendation T.503 for facsimile documents, but takes into account the
ODA extensions for tiled raster images.  This DAP is also expected to
referenced by the MILSTD 28002.

The ODA SIG recently meet in conjunction with the September 10-14,
1990 NIST OIW Workshop in Gaithersburg, Maryland.  Several significant
decisions were taken by the NIST ODA SIG and endorsed by the
Workshop Plenary.

The Working Agreements for all three DAPs have been modified to support
in one specification both the ODIF (binary encoding based on ISO
8824/8825, ASN.1) and the ODL/SDIF (clear text encoding based on ISO
8879, SGML) interchange formats.  Support for the SGML encoding of
ODA is perceived as a requirement in North America for acceptance of
ODA documents.  The recent NIST sponsored Electronic Document
Processing Confererence on July 30, 1990 explicitly emphasized this
requirement.

The NIST Level 2 DAP is the final stages of international alignment with
European (i.e., European Workshop on Open Systems) and pacific rim (i.e,
Asian Oceania Workshop) ODA experts within their respective regional OSI
workshops.  This effort is complemented by the recent CCITT Study Group
VIII Plenary decision to process an equivalent text for this DAP as a
CCITT Recommendation.  This proposed international standardized profile
is called FOD26.  It is expected to be submitted at the end of October to
ISO for processing as an International Standardized Profile.  This is a
registration process for international profiles.  It is expected that the NIST
Level 2 DAP will be included in the OIW Stable Agreements published as
a result of the December 1990 OIW.  The NIST ODA SIG recommended
to NIST that the NIST Level 2 DAP be the basis for GOSIP Version 2
support for ODA.

EWOS has processed an equivalent form of this DAP in Europe as a
European Temporary Norm (ENV), Q112.  It is understood that support for
this DAP became mandatory in the CEC in August 1990.  For three years,
the Piloting of ODA Project within ESPRIT has sponsored ODA
interworking demonstrations at the CeBIT MESSE in Hannover, Germany.
Q112 was the basis for the March 1990 demonstration.

The NIST Level 3 DAP is maturing about six to nine months behind the
NIST Level 2 DAP.  The international alignment for this DAP is expected
to be completed in March 1991.

The NIST Raster DAP is be developed in response to a requirement from
the technical document community for an agreement for scanned technical
drawings of numerous page sizes.  This DAP is also being shared with the
EWOS ODA experts.  The final draft text of the DAP is being circulated
to the CALS community by NIST.

The next meeting of the NIST ODA SIG is schedule for December 11-
13, 1990 in conjunction with the next NIST OIW, in Gaithersburg,
Maryland.  Contact Brenda Gray, 301-975-3664, at NIST for more details
concerning this SIG and other OIW activities.
