Leo Sauermann and his Gnowsis (“the Semantic Desktop environment published by the Knowledge Management Lab of the DFKI. Gnowsis is a reference implementation of parts of the Nepomuk Semantic Desktop framework.”) … and yaa, NEPOMUK.
And Kayuda, a web-based approach to concept-mapping (see the blog and forum) … that’s pretty rich and heady stuff!
What pops up suddenly (from Kayuda’s blog)? Vic Gee’s Mind-Mapping.org, “Vic’s compendium of software that supports knowledge management and information organisation in graphical form. Includes mind mappers, concept mappers, outliners, hierarchical organisers, KM support and knowledge browsers, 2D and 3D.”
No kidding.
First signs of a concept-mapping tsunami?
