Hi,
after reading some parts of the user manual and searching in the
newsgroup I could not find out if it is possible or practical to modify
(refactoring in my case) a model directly without creating a new one.
Did I miss something? If I understand the refining execution mode
correctly it still creates a new model copying the elements that have
not been touched.
In my case I can have a huge model where duplicating it is not an option.
What do you think?
Bye,
Sandro

that's too bad, because I would be glad to work with ATL. E.g. stepping
through a transformation and seeing the actual values using a debugger
is a nice feature.
Anyway, thanks for your feedback. It's good to know that.

In my case I would like to modify a model backed by a JCR
( http://en.wikipedia.org/wiki/Content_repository_API_for_Java) for JCR
Management (http://www.eclipse.org/emft/projects/jcrm/). Such a
repository could be too big to get duplicated.
Best regards,
Sandro
