Large-Scale Knowledge Management for Collaborative Work

Collaborative work is performed these days independent from organizational and geographical bounds. The number of participants and usage scenarios result in a need for large-scale distributed knowledge management. In this paper we present Wasabi as a platform for such environments by considering e-Health as an example field of application. Thee-Health scenario has specific requirements to handle complex data objects and to strictly ensure data privacy. This paper describes how to handle such complex data objects within a knowledge management system. In order to ensure data privacy, the integration of known authorization and authentication mechanisms in Wasabi and their usability for distributed knowledge environments are discussed.
