Hey everybody,

I'm trying to create an Ecore Diagramm for Petri Nets (see attached file)

Every element of the Petri Net should have an ID which should automatically be incremented. Is ist possible to model it in the ecore diagramm (Couldn't find anything in the properties of the EAttribute)

Another question: Is it possible to overwrite inherited EAttributes?

Thanks in advance!

Using the ecore diagram you'll be able to model that the EAttribute is an ID (id=true). But for the auto-increment part you'll need to add your logic in the generated Java code.
