Hi

Interesting proposal.

When I have time, I try to pursue a graphical front end for QVTr under
the GMT/UML project. When the GT foundation is properly established
many of the graphical language differences degenerate to presentation
preferences, so it would be good to support a variety of concrete
syntaxes to suit user prejudices.

I notice that your editor is at least multi-sheet and multi-pane,
whereas GMF is currently single sheet, although the Notation supports
multi-sheet. It would be helpful to try to establish a re-useable added
value layer on GMF to support these concepts since I'm sure many
projects would like to use them.

Regards

Ed Willink

We also believe that the user should have a choice for the concrete
syntax and moreover that graphical notations are well-suited for model
transformations.

Very true. Currently we use only the Notation model and parts of the GMF
runtime. Actually the editor in the screenshot is pure EMF+GEF, but for
the EMFT project we are reimplementing everything more or less from
scratch. I also agree with you that multi-sheet support in GMF would be
really nice. It certainly would make our life easier ;). Anyway, I don't
think that our code can be a basis for extending GMF in that direction,
since it is too specific to our editor.

Cheers,
Christian
