Back to the previous slide, on to the next slide or up to the communications overview

The previous discussion has pointed out how the communications based on models can be used to facilitate future applications. The ability to create and use these models will dramatically increase the flexibility of the applications we will create in the future.

A number of research questions need to be addressed though. How can we effectively create electronic models? What sort of language will be used for describing physical objects and decision making procedures? Can systems be created to simplify the creation of models sufficiently that their creation can be a part of everyday life?

Once models are created how do they intereact? What are the set of operations that negotiating agents use? How does one create an efficient, large scale simulator that combines aspects from several different models?

And finally, how does one store models? This must be done so that the models are accessible by machines of widely varying capabilities and in ways that can protect the private data inside the models.
