[news.eclipse.tools.emf] Re: [Q] Is there a way to update content of Res

[Ed Merks <merks@xxxxxxxxxx>]

Tomas,

It would be very interesting to have an incremental "reconciler". Such a thing
would really be like a "diff"ing tool, only structure-based rather than text
based, and the diffs could be used to drive updates to the original model to
make it like the changed model.   I think it's a pretty hard problem to solve,
but oh so useful with so many applications.  We don't have any immediate plans
in this area, so contributions would be ever so welcome.  ;-)
