The emergence of the new interconnected workspace will produce the effect of new WEB. The terminals of the network will be no more 2D with the reduced interactivity but a multisensory immersive space, with the greater manipulatory interactivity and with various effects of mixed reality. Installations as The Cross-Platform Graphics Library (CGLX of CALIT2) will require new management modes of the knowledge which will generate their uses. We shall wonder about the emergence of new modes of filing, correlation and semantic classification of the multimodal contents and their meta-data engendered by the exchanges using the Immersive Communicant Environments.
