The document proposes the Slikipedia project, which combines Wikipedia with Second Life to create 3D virtual libraries and learning environments. It discusses using the virtual world to allow collaborative editing of objects that represent information. This would create an "allegorical infoscape" where collective intelligence is manifest spatially. Theories of communication, cognition, and learning are reviewed that support how a 3D environment could augment understanding through spatial representation of ideas. Challenges of quality control and ensuring collaborative knowledge creation are also addressed.
