Hi all,

i have a general question about M2M Transformation:
I transform a source-model which conforms to an Ecore-metamodel (A) to a output-model which conforms to an Ecore-Metamodel (B).
The Ecore-metamodel B was generated by importing a XSD with EMF's model importer.
Now QVT serializes the output model as XMI, but the objective is to produce XML files.
Do i have to implement another transformation wich transforms the XMI Output Files to XML Files which conform to the XSD ? Or is there some kind of "exporter" that can generate XML files ?

thanks in advance

Hi

This seems like a bug.

I think genmodel could have created a special XxxResource(Impl) and
XxxResourceFactory(Impl) for your Xxx meta-model. Has it?

If you use the corresponding *.xxx file name, QVTo could use the
XxxResourceFactory(Impl) which could set the save options to serialize
correctly. Are you using *.xxx?

Regards

Yes xxxResourceFactoryImpl and xxxResourceImpl are generated from the genmodel. I deployed the project as plugin and use it as output metamodel of the qvt-transformation.

I don´t realy understand that part. Do i have to modify the XxxResourceFactory(Impl) in order to tell QVT the serialization format ?

Hi

I've not used XSD configuration, so my answers are just based on what I
would expect to work.

Normally during a save, a map of saveOptions should be merged, one from
the code invoking save and one from the ResourceFactory enabling the
ResourceFactory to ensure that whatever is needed for XSD is done.

I would try using the Sample Ecore Editor to Create a Dynamic Instance
of a class in your meta-model and see whether the saved instance looks
good. If so, the ResourceFactory is working, and you need to find out
why QVTo is not invoking Resource.save correctly. If not, read the EMF
book to find out how XSD save is supposed to work.
