[Modeling] Modeling an Agent Class- register your opinion

[f.tolman]

Dear collegues

I would like to see the model that contains everything that we need first in
UML. I agree with most of you that we probably need something more to
describe the dynamic nature of agents. In the discussion however we seem to
mix the things that we want beyond the UML model with the UML model that we
still don't have. It is very difficult to agree about the extensions if
there is no agreement about the basics.

Regards


Frits
