This volume is a record of the Workshop on Graphics and
Communications organized within ESPRIT II Project 2463 ARGOSI
(Applications Related Graphics and OSI Standards Integration). The
workshop was included in the Eurographics workshop programme for
1990. The ARGOSI project essentially arose from the observation
that international standards in the graphics and networking areas
were generally being developed in isolation and that insufficient
attention was being paid to the needs of applications whose
requirements spanned several standards. The importance of the
integration of graphics and networking has been growing over recent
years, with the growth of interest in multi-media systems to
support cooperative working, and the use of computer graphics
techniques in the visualization of the results of scientific and
engineering computations. The latter frequently involve high-speed
links between workstations and supercomputers. The presentations in
this volume cover a broad range of activities from a classification
scheme for graphics and networking to interconnection experiments
with broadband networks. Three topics were selected for detailed
discussion in working groups: - Improvements to the computer
graphics metafile standard, - The role of application profiles in
graphics data exchange, - The impact of multi-media. The volume
contains a record of the discussions and the recommendations from
the working groups, subsequently endorsed by the workshop.
This volume is a record of the Workshop on Window Management held
at the Ruth erford Appleton Laboratory's Cosener's House between 29
April and 1 May 1985. The main impetus for the Workshop came from
the Alvey Programme's Man Machine Interface Director who was
concerned at the lack of a formal definition of window management
and the lack of focus for research activities in this area. Win dow
Management per se is not the complete problem in understanding
interaction. However, the appearance of bitmap displays from a
variety of vendors enabling an operator to work simultaneously with
a number of applications on a single display has focussed attention
on what the overall architecture for such a system should be and
also on what the interfaces to both the application and operator
should be. The format of the Workshop was to spend the first day
with presentations from a number of invited speakers. The aim was
to get the participants aware of the current state of the art and
to highlight the main outstanding issues. The second day consisted
of the Workshop participants splitting into three groups and
discussing specific issues in depth. Plenary sessions helped to
keep the individual groups work ing on similar lines. The third day
concentrated on the individual groups presenting their results and
interacting with the other groups to identify main areas of con
sensus and also a framework for future work."
This volume is a record of the Workshop on User Interface
Management Systems and Environments held at INESC, Lisbon,
Portugal, between 4 and 6 June 1990. The main impetus for the
workshop came from the Graphics and Interaction in ESPRIT Technical
Interest Group of the European Community ESPRIT Programme. The
Graphics and Interac tion in ESPRIT Technical Interest Group arose
from a meeting of researchers held in Brussels in May 1988, which
identified a number of technical areas of common interest across a
significant number of ESPRIT I and ESPRIT II projects. It was
recognized that there was a need to share information on such
activities between projects, to disseminate results from the
projects to the world at large, and for projects to be aware of
related activities elsewhere in the world. The need for a Technical
Interest Group was confirmed at a meeting held during ESPRIT
Technical Week in November 1989, attended by over 50
representatives from ESPRIT projects and the Commission of the
European Communities. Information exchange sessions were organized
during the EUROGRAPHICS '89 confer ence, with the intention of
disseminating information from ESPRIT projects to the wider
research and development community, both in Europe and beyond.
The offices of GMD-FOKUS in Berlin provided the venue for a meeting
in December 1987 which signalled the birth of the ARGOSI project.
The proposal gradually took shape over the following months, and
after merging with another project proposal in the field of
standardization of computer graphics, finally received funding from
the Esprit programme in March 1989. The project stemmed from a
recognition of the importance of computer graphics a'i an ena bling
technology in many application areas, and of the need to build
bridges between computer graphics and telecommunications. The
overall aims of the pro ject were twofold: * Advance the state of
the art in the transfer of graphical information across
international networks. * Improve quality and applicability of
standards in this area. This book records the key results of the
project and the contributions the project has made to
standardization related to the transfer of graphical information
across open networks. Contributions have included a demonstration
of a prototype appli cation - a road transport information system
running over public international of a new data networks - shown at
the Esprit '91 exhibition, the standardization FT AM document type
allowing structured access to graphical information (represented
according to the Computer Graphics Metafile (CGM) standard) and
major contributions to a mapping of the X-Windows protocol onto an
OSI stack. The project also organized two international workshops.
the first on Graphics and Communications, and the second on
Distributed Window Systems.
