Hi,

i need transform java models (.xmi files) with qvto. All the qvt examples that i seen, establish as MODELTYPE .ecore metamodels (no models) only.

My question is: How do I tell qvt that i'll transform XMI models?

Regards

Hi

I've wondered too, but never really thought it through.

QVTo just transforms conforming model instances, so if you want it to
transform XMI instances, you must write your transformation against the
XMI metamodel and load XMI instances.

If you ensure that your source files are *.xmi, it should just work.

If you want to process a *.xyz file as *.xmi, there is probably a
bug/enhancement that QVTo should recognize the XMI metamodel and
suppress the use of a *.xyz loader.

Hi Ed,

Basically that i need is define a java program, then generate a model for it qhit MoDisco Discoverer, transform it and finally obtain the java program again.

I would make the transformation with QVTo.

The MoDisco Java Discoverer generates a .XMI File.

What is the most appropriate way to do this according to you?

Regards.

Hi

I'm struggling a bit with your typos, but I'm afraid that if you did not
understand my previous answer you should look at tutorials to give you
familiarity with the technology space.
