I found UML2 component that propose the used/provided services ports. That is usefull for SOA (Service Oriented Architecture) architecture modelisation.
But I'm looking for Events port: consumed/provided events. They are mandatory for EDA (Event Driven Architecture) modelisation, and I don't find them in modelio.
Current complex system modelisation require the both architecture SOA and EDA paradygms. And I think that modelio shall provide them.
May CCM, or you study case named Jacomo, component model, that both propose services/events/attribute (or parameters) port types, can be a leading component model example.
