Hi Luciana & All,

This is also my concept at this point.  There is a mindmap tool
written in GMF that Acceleo uses in a demo to generate XHTML slides.
The point is that GMF "should" provide the ability to create a MLHIM
specific  CDD to edit the models for CCDs before generation.

The only thing that we need to discover is how to create the editor
and then how  the instances of the CCDs will becreated.  The concept
prior to Acceleo was that HKCR would create models that used UUIDs to
name the classes in a CCD.  I feel that this is still the direction
that this effort will move. But the details are yet to be confirmed.

For anyone that isn't aware of why that last paragraph is important.
Remember that you must have unique class names in your CCD model.  For
instance, let us say you have an ItemList with three Element entries.
Each of those Elements must be uniquely named in order to build unique
paths to them.  There are more complex examples but I think that makes
it clear?

Thanks for the perspective Luciana,

Cheers,
Tim
