Flexible notifications and task models for cooperative work management

2005 , Rubart, J. , Richter, H.

Knowledge intensive cooperative work requires emergent workflow management. Participants interact with the workflow engine and jointly redefine and activate workflow structure. To improve the usability of such systems we present reconfigurable notification mechanisms as well as shared task models that can be used from diverse clients at the same time focusing on different kinds of visualization and navigation.

A meta-modeling environment for cooperative knowledge management

2003 , Rubart, J. , Wang, W. , Haake, J.M.

Knowledge management (KM) systems usually focus on specific tasks. In this paper, we identify B- and C-level improvement activities for cooperative KM based on Engelbart's ABC model of organizational improvement. We present a cooperative meta-modeling environment, which is based on cooperative hypermedia. It supports the configuration of domain-specific knowledge schemas and their ad-hoe adaptation with special consideration of behaviors.

A cooperative visual hypermedia approach to planning and conducting virtual meetings

2002 , Wang, W. , Haake, J.M. , Rubart, J.

Most distributed meeting support systems focus on meeting management and audio/video communication mechanisms. They provide little support for a flexible meeting process and a shared information space with structure- rich visual artifacts. A cooperative visual hypermedia system is developed to provide visual hypermedia artifacts for team members to manipulate in a distributed meeting. The visual hypermedia system is a hypermedia-based drawing system that integrates visual hypermedia artifacts and structures found in multiple hypertext domains. In addition, the visual hypermedia is integrated with process support for flexible meeting control and for easy setup of audio/video and application sharing communication channels. A use case is presented, which shows that using the cooperative visual hypermedia, distributed teams can perform many kinds of meetings, in the meantime, enjoying dedicated support for the planning, control, information management, and follow-up activities of a distributed meeting.

The EXTERNAL experience on system and enterprise integration

2004 , Wang, W. , Lillehagen, F. , Karlsen, D. , Johnsen, S.G. , Krogstie, J. , Rubart, J. , Haake, J.M.

The overall objective of the EXTERNAL project is to make it easier for business partners to form and operate extended enterprises as dynamic networked organisations. From a technical perspective, EXTERNAL, is largely a system integration project, in which a set of complementary tools are integrated into a Web-based knowledge sharing infrastructure to provide a comprehensive set of services for EE engineering and operation. As a result from our evolving understanding, we shifted from system integration and an Information and Communication Technology (ICT) infrastructure towards enterprise integration and an intelligent Extended Enterprise infrastructure based on Active Knowledge Models.

Towards UML-G: A UML profile for modelling groupware

2002 , Rubart, J. , Dawabi, P.

Groupware is explicitly designed to support the cooperation among group members. The implementation of cooperation-aware groupware is supported by several object-oriented toolkits and frameworks, but there is no unified way to model applications built on top of these. We propose UML- G as an extensible UML profile for modelling groupware and want the community to contribute to it. We identify groupware specific modelling needs related to shared data modelling. Since these needs are not addressed by standard UML, we define UML-G's shared data modelling part. Usage scenarios demonstrate how UML-G can be used to assist groupware modelling. UML-G supports explicit modelling of groupware related needs. Moreover, a shared understanding between developers is backed, which abstracts from the implementation. In addition, CASE tool support for UML-G strengthens its practical relevance.
