Capella Data Class Diagrams Metamodels

Hello Everyone,
I wanted to extract data from Capella [CDB] Model. I will be needing information about the metamodels of this diagram to know how each class is connected and how to call it. I was asking if there is a way to know what metamodel is related to this part of capella or if there is any other ways to query this part of the model using Acceleo
Thanks,
Mark Georgy
