simple BPMN ecore metamodel

Question

I'm trying to build my own simple BPMN ecore metamodel by simplifying built one by OMG specification, with little change on dependencies between elements.

When you write "correct" you need to specify with respect to which one. If you mean with respect to BPMN2 standard, then you need to compare your metamodel with the standard one.
