We are going to widen the scope of the investigation.
We have introduced the notion of scopes as a powerful structuring mechanism for event-based systems.
Units in a system could easily be re-grouped into units of different scales to cope with problems of different scopes.
Two mapping components are required to constrain the visibility of the transformed notifications to the appropriate scopes.
We have also given a formal specification of event systems and scopes and event mappings within a trace-based formalism adapted from temporal logic.
Events can only cross the boundary in a downward direction and no other features of scopes are mentioned.
More specifically, topics tend to have wider scopes as predication is involved.
Note that there is no intended counting of scopes with the new primitives.
Extending confined types with generics achieves some of the flexibility of ownership types, but the number of scopes remains bounded.
