Best way to handle multiple emf models when generating gmf editors? [message #225498]

Hi

I'm working on a project in which we split a large emf model into
smaller ecore files so as to be easier to configuration manage in
sourceforge and edit separately. We are also loading uml and emf models
for data types etc.

When it comes to creating gmf editors I'm looking for an idea of what
is considered best practice.

Should I somehow merge the individual emf models into a monolithic gmf
editor, OR should I perhaps have a series of gmf editors linked by a
wizard (each editor corresponding to the individual emf models).

If the monolithic editor is possible, could someone suggest a reference
or at least what magic words I need to google for ;-)

(Previously I had a single DSL which grew quite large and not quite
so Domain Specific as things were added, then I just generated a single
GMF editor in the normal way)

thanks
Steve

You have to choose between single and several GMF editors based on your requirements
– it is possible to implement each of suggested solutions.

If you decide to create single diagram editor then just describe it in single
..gmfmap file and generate corresponding code. You can possible face some
problems with the containment references – sometimes you can wish to store
some particular diagram node in a separate resource (not the one used for
parent node/diagram itself). In this case you have to patch generated code,
but it’s not so hard, so I’m suggesting you start with implementation and
ask additional questions later.
