[Modeling] Modeling an Agent Class- register your opinion

[Dr. Hong Zhu]

There is an issue of different levels of abstractions, here. I would
consider class (or agent class) as a language facility that supports the
implementation of a number of more abstract concepts in modelling and
problem analysis. Role is an abstract concept that agent class supports. I
have discussed this in a paper 'Representation of roles in caste'. There is
a close match between the concept of role and the language features of caste
(agent class).
