PublicationTowards 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.
PublicationA 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.
