Hi all,
I would like to transform a Cifx metamodel to an Ariadne metamodel. To get started, I used this code:
modeltype Cifx uses "platform:/resource/Files/Cif2.ecore"; --"http://se.wtb.tue.nl/cif/cif-2.1.0";
modeltype Ariadne uses "platform:/resource/Files/ariadne.ecore"; --"http://ariadne.org/ariadne-1.0.0";
transformation CifxToAriadne(in modelIn:Cifx, out modelOut:Ariadne);
main() {
log("In Main");
log (Cifx::Model.allInstances()->size().toString() );
log( modelIn.objects()[Model]->size().toString() );
log( modelIn.objectsOfType(Model)->size().toString() );
log( modelIn.objects()->size().toString() );
log( modelIn.objects()->asOrderedSet()->at(2).metaClassName() );
My instance of the Cifx model has a rootObject Specification, with a child Model. The further transformation didn't return results, so I wrote three lines which print out the number of Model objects, and one for the total amount of objects. The code above returns these results:
In Main
0
0
0
219
Model
But there IS a Model object, the last print says so itself!
How is that possible? I need to transform the Model from the Cifx model to Ariadne, but because QVT says there aren't any models present in the Cifx instance, my transformation obviously doesn't work.

Hi PBarendrecht ,
Could you please post metamodel 'Cif2.ecore' and input model used for
the 'in modelIn:Cifx' here.
Note on posted example - it's better to reference metamodel using NsURI.
Correspondence 'NsURI' to 'workspace metamodel location' is established
using "Project Properties/QVT Settings/Metamodel Mappings".
Regards,
Sergey.
