[newbie] EMF and UI [message #419341]

Hello folks,
I have an EMF model for data (that goes to an XML file). And an editor for
that model.
If I am right the editor is 1:1 with the data-model and in this case
everything I do on the UI is automatically reflected into the file when
saved.
UI<->EMF<->XML
this is good because have the command-stack correctly updated to every
action I do in the UI.

but what I would like to achieve is something like:
UI<->UI EMF <-> XML EMF<->XML
(ui domain | under the hood domain which is separeted from
the user inteface)

where the "UI EMF" should be the data represented in the editor and the "XML
EMF" is the data saved to the file (which is a subset of "UI EMF").
What is your suggestion on where to start?

Thanks in advance
Luca

From a UI point of view, it's the generated item providers that
determine how the UI displays the data. So you can fiddle with those to
hide children, display virtual children, and so on. Probably it will be
good to read the EMF Edit overview to get a sense for how this works.
