Hello,

I want to query a EMF model in standalone mode. It seems that EMF query does not have this feature.

So, my question is: Can I use qvto for querying and retrieving data from the model?. I ask the same question in QVTo forum (https://www.eclipse.org/forums/index.php/t/1099763/) but I think this forum is more active than the other one.

Regards,

Daniel.

Hi

Yes you can use qvto to query a model, provided you are happy to have the result presented as a model, which might conform to a trivial metamodel containing a Result class and a value property.

Sorry the QVTo forum does get responses, but unfortunately the FUDforum RSS feed is very flaky; your posting has yet to be propagated to my Thunderbird RSS client.

Regards

Ed Willink

Thank you for the response.

I am using QVTo with Java and the idea was to query the model with QVTo and to get the result in Java in order to manipulate it. So finally, I implemented classic OCL queries and that was enough.
