Collaborative visualization

In DIVA, multiple users can have their own presentation model (perspective) while sharing a common resource. However, in this approach the different users have the feeling that they are the only user of the shared resource. There is not yet support that allows a user to be aware of other users or to interact with them. Our goal is to expand the architecture to support users to collaborate with each other. Here, 'to collaborate' means that the users are able to discuss visualized information in order to reach a decision.

The next section will address the issues that are involved in this restrictive notion of collaborative visualization. Then, we will discuss the requirements for an extended DIVA architecture in Section 4.2.
