It would be great if objects on models has GUID. It can help in future for models import to ARIS professional tools. For example, you create object ‘Person’ in Org.chart in ARIS Express. Of course, when you copy object ‘Person’ to EPC model in ARIS Express there are no links created between models in ARIS Express, but when you import these EPC models to ARIS BA, for example, you can identify that these ‘Person’ objects have the same definition. To my mind, it would help us to create more ‘methodological’ approach in ARIS Express.
