A collaboration with three roles and three collaboration uses:

• may define a service structure

Session

roleX:TypeX roleY:TypeY

A collaboration with two roles:•may define a semantic connector

•TypeA must be compatible with (the semantic interface) TypeX•Compatibility means that the role behaviours must be contained in the total behaviour of the actor – how is a semantic variation point in UML2

Behaviour can be in three places:– The collaboration itself

– The roles

– The context (scope) of the collaboration:

The Taxi System with interfaces bound as collaboration uses

This is a composite class with parts.Each part shall satisfy the roles bound to it
