[news.eclipse.tools.gef] Re: GEF, EMF and semantic vs. graphical model

["Randy Hudson" <none@xxxxxxxxxx>]

I have seen a generic EMF-based diagram model implemented in the past and it
was not successful. I don't know of any ongoing efforts for this type of
work. It doesn't fall under the scope of the GEF project charter.  The VE
project might include a base view model like what you are suggesting.
