Vega Information Grid for Collaborative Computing

This paper looks at computer supported cooperative work (CSCW) from an information grid viewpoint. We illustrate two collaborative instances in information grid and point out new CSCW requirements. We discuss key pieces of two models in the VEGA-IG (VEGA information grid): model of object and that of subject, which help the achievement of collaborative work and partly solve the difficulties in collaborative work such as unknown participant, dynamic cooperation channel, multi-modal communication, dynamic participants and resources. The two models take loose coupling as their main point and shield many complicated information of the collaborative work. We also discuss two examples of collaborative work in VEGA-IG.
