Hello Community,

is there a way to generate a weaving model out of an ATL transformation?
My problem is the following: I do have a weaving model Mw which hold refs to 2 different metamodels Ma and Mb. I also have a transformation which transforms Ma to a new Mc. What I need now is to update the refs in Mw of Ma to Mc. If the weaving model would work on the model level this would be no problem, then I could use the trace model approach. But the weaving model references into the metamodels Ma and Mb, so the tracing approach does not work.

Any ideas?

Greetings Simon

Hi Simon,

You can create a weaving model from an ATL transformation by implementing a higher order transformation, i.e., a transformation that takes as input an ATL transformation model Mt and that produces as output a weaving model Mw'.

For instance, for every rule in Mt you can produce a WLink, and for every binding within the rule you can produce a WLinkEnd. To do that, you need to know the metamodel of ATL.

Otherwise, what is the relation between Mb and Mc? Mc is a new version of Mb? In this case, you may check the metamodel difference approaches ( http://www.eclipse.org/m2m/atl/usecases/MMIndApproachtoDiffR ep/). They focus on representing the differences between metamodels, not on updating the weaving model, but it could be an inspiration Smile .

Regards,

Marcos.
