Hello ATL Community,

i am currently developing a model-to-model transformation from a model A that references UML2 to another model B that also references UML2.

What i am trying to do now is the following:
Lets suppose there is a class AA in model A that has an attribute "type" which references to an UML2 class. This class AA should now be transformed to a class BB from model B which also has this attribute "type" which references to an UML2 class. How can i define in a transformation rule that it just should keep the reference? Do i have to do "model weaving" or is there a simpler way?

Regards,
Bastian Mohrmann

Are A and B both expresssed in the UML language? Or are they metamodels that extend the UML2 metamodel?

Cheers,
Dennis

  1. Enable "allow inter-model references" in your ATL launch configuration
  2. Make sure that the "type" EReference you mentioned is not a containment reference
  3. Do not transform the referenced UML2 EClass

Cheers,
Dennis

Thanks Denis, it works now.

I followed the three advises you gave and everything is fine now.

Sorry for the late response. Regards,
Bastian
