The main results of this work include \(i\) precise specification of interaction protocols depending on the type of middle\-agent \(this can also be a basis for characterizing types of middle\-agents\), \(ii\) improvement of communication between designers and developers and facilitation of formal verification of agent systems, \(iii\) guided design and implementation of agent\-based software systems that incorporate middle\-agents."]
