In this short position paper, we sketch three ongoing projects
(KnowMore, ENRICH, and Know-Net) currently running
in the Knowledge Management Group of DFKI investigating
requirements and approaches to support Knowledge
Management (KM) infrastructures for organizations.
We also list some promising research issues to be tackled in
the near future to come from individually designed KM prototypes
towards a rich, modular KM middleware as a solid
basis for engineering Intranet-based KM solutions.
