hi

i'm trying to build my own ecore model using the ecore diagram, and i wanted to know if it is possible to import an ecore in another ecore ?
for example:
i have 4 ecore files A.ecore , B.ecore , C.ecore , D.ecore, and since in my ecore A and B i am using D and in my ecore C i am using B , i don't want to redefine A, B and D everytime i want to use it. so i'm looking for a way define it one-time and just import it any time i need it.

and if it is possible how can we do it (represent it) using an ecore diagram
Best regards ,
Frank

Hi,

in the Sample Ecore Editor you can use "Load Resource ..." dialog from context-menu.
In the diagram editor you might want to use "Create Shortcut" instead and in the opening dialog you can select the class you want to re-use.

Regards,
Tim

Hi Frank,

what do you mean with "fixing" an attribute?
You can specify constraints on your model, for example with OCL.
If that's what you mean, it's best to use the OCLInEcoreEditor
http://wiki.eclipse.org/MDT/OCLinEcore

Tim

XML Schema supports simple data types with these types of range
constraints and EMF supports extended metadata annotations for
that. You'd have to define a specialized EDataType for that.
