Collaboration in cooperative information systems, like concurrent
design and engineering, exploits common work and information spaces.
In this paper we introduce the TOGA service (Transaction-Oriented
Group and Coordination Service for Data-Centric Applications), which
offers group management facilities and a push model for change
propagation w.r.t. shared data, thus allowing for group awareness.
Through TOGAs customizability and its layered architecture the
service can be adapted to a variety of different collaboration
scenarios. Multiple communication protocols (CORBA, UDP/IP, TCP/IP)
are supported as well as basic transaction properties. Our approach
enables both, firstly, the evolution of a set of separate
applications to form a cooperative information system, i.e., it
provides a technique towards component-oriented system engineering.
Secondly, it can be exploited as a basic service within
collaboration frameworks to effectively manage common work and
information spaces. In this paper we report on design issues,
implementation aspects, and first experiences gained with the TOGA
prototype and its exploitation in an activity coordination and
collaboration framework system.
