    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.

    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.

    The trend towards rapid development and globalization of business activities requires business teams to carry out their projects in a distributed environment. Changes in the environment as well as in the team require these teams to continuously learn and to learn new knowledge and skills and to adapt their work processes. In such a distributed working and learning setting, team members need a shared information space to interact with various information resources and to coordinate and communicate to harmonize their actions. In our approach we combine work (i.e. the definition and execution of work processes) and learning (i.e. the learning and practicing of work processes) of distributed project teams. A cooperative visual hypermedia environment has been developed which offers support for cooperative work and learning. This visual environment provides various real-time dynamic views of the underlying work processes. These views help team members to identify situations that trigger a need for cooperative learning. By combining the work and the learning processes, this environment offers new possibilities for cooperative learning in distributed project teams such as process simulation, guided tours by experts through process descriptions and best practice examples, and cooperative roleplay for practicing work processes.

    Collaborative learning has proven to be a successful method in traditional classroom settings. Computer-supported collaborative learning (CSCL) is regarded as a new paradigm in educational technology. Nevertheless, in the context of infrastructures for lifelong learning, little attention is paid to collaboration. We provide an analysis of lifelong learning with respect to collaborative learning. In order to support the variety of collaboration modes and learning methods in lifelong learning scenarios, existing approaches to learning infrastructures must be extended in a number of directions, e.g. with respect to user management, collaboration management, communication/collaboration functionality, support for (transitions between) different learning modes, and awareness of peer learners. We introduce our approach to an infrastructure for collaborative lifelong learning, which is based on integrated collaboration functionality, transitions between different learning modes, and a scalable standards- based architecture. We sketch two implementations of this approach in an internal as well as a multi party distributed setting and report first experiences.

    A cooperative visual hypermedia approach to planning and conducting virtual meetings

    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.
