In this paper, we report about the design, development, and implementation of the SEPIA cooperative hypermedia authoring environment. It provides results on the following aspects of SEPIA: persistent and shared data storage, hypermedia data model with composites, sophisticated and comprehensive authoring functionality, support for a new rhetoric and for(More)
hypermedia, it is necessary to distinguish between two kinds of applications: “One encourages those who wish to wander through large clouds of information, gathering knowledge along the way. The other is more directly tied to specific problem-solving, and is quite structured and perhaps even constrained” [20, p. 119]. Applications of the first type appear(More)
This paper introduces COAST, an object-oriented toolkit for the development of synchronous groupware, which enhances the usability and simplifies the development of such applications. COAST offers basic and generic components for the design of synchronous groupware and is complemented by a methodology for groupware development. Basic features of the toolkit(More)
Work processes in team based software development need to be structured to minimise and resolve conflicting or divergent work. Current software development methodologies propose ways for dividing the whole task of software development between team members. This paper suggests a different way of working by introducing modes of collaboration (MoCs), which(More)
Early hypertext systems were monolithic and closed, but newer systems tend to be open, distributed, and support collaboration. While this development has resulted in increased openness and flexibility, integrating or adapting various different tools, such as content editors, viewers or even other link servers has remained a tedious task. Many developers(More)
At the German Distance Learning University, five collaborative distance learning scenarios have been recently identified by students and teachers as an important future form of collaborative learning in the university’s virtual learning space. An analysis of these scenarios showed a great variance between them and a need to support run-time tailoring of the(More)
In this paper, we present a cooperative hypermedia based process support system focusing on flexible business processes. An analysis of the communication, coordination and cooperation requirements of business processes reveals a gap in current computer support. We propose to address these requirements by extending a cooperative hypermedia system with(More)
This paper describes DOLPHIN, a fully group aware application designed to provide computer support for different types of meetings: face-to-face meetings with a large interactive electronic whiteboard with or without networked computers provided for the participants, extensions of these meetings with remote participants at their desktop computers connected(More)
