Dear Ed,
thank you on answer.
I need three packages in one file, because I have two languages and their metamodels (let say UML and BPMN), and I want to create the third language by using concepts from both languages (some hybrid of these two). Then, I need to generate GMF app from this (one) ecore file.
Is this good solution?

thx, Milan

I can't imagine why you'd need to create three packages in one Ecore
file. Personally I'd suggest that's a bad idea. One package per file
seems better. Certainly one root package per file is pretty much
necessary, so you could create one root package with three subpackages,
but again, I'd advise against that. Perhaps you should explain why you
consider this a need?

The need for three Ecore models, i.e., three EPackages, in no way
implies a need for three models in one file, regardless of how these
three models might be related to each other.

It sounds like you're focus on the wrong detail. You can have three
package is three different files and those packages can be related in
any arbitrary way...

Absolutely. This tutorial will help you understand a little better maybe:
Tutorial: Generating an Extended EMF Model
< http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.emf.doc/tutorials/slibmod/slibmod.html>
> And also, to show all of these elements in one ecore diagram (as i

Yes, you drag and drop things from the outline onto the canvas. And
there's a Load Resource... action for loading in other Ecore models so
you can refer to them and display them.
> and later to generate GMF app from this?
Yes, the above tutorial will help prepare the EMF GenModel you'll need.
Note that if you have mutually dependent Ecore models, they'll need to
be contained by a single GenModel. For one way dependencies, you can
put them in separate GenModels as in the tutorial above.

You'll find you're unable *not *to do this. No matter which model you
load first, EMF will load all the ones it depends on and will force you
to create a GenModel for them all, or to locate an existing GenModel.

Dear Ed,
thank you on your answers. I have one more question related to this subject, I need to define BPMN 2 metamodel related to its specification, but in spec. it includes some packages (activity, data, etc.). So, you propse not to put all of these in one file, e.g., bpmn2.ecore, but to have each package in its separate file?

Milan,
Personally I prefer separate packages. Sometimes people use nested
subpackages, but often that results in subtle issues because it's not so
well tested/used.

Dear Ed,
thank you on answer.
I need three packages in one file, because I have two languages and their metamodels (let say UML and BPMN), and I want to create the third language by using concepts from both languages (some hybrid of these two). Then, I need to generate GMF app from this (one) ecore file.
Is this good solution?

You'll find you're unable *not *to do this. No matter which model you
load first, EMF will load all the ones it depends on and will force you
to create a GenModel for them all, or to locate an existing GenModel.

Absolutely. This tutorial will help you understand a little better

Yes, I read this tutorial already, but obviously I missed this part
with split files.

you drag and drop things from the outline onto the canvas. And there's
a Load Resource... action for loading in other Ecore models so you can
refer to them and display them.

Yes, the above tutorial will help prepare the EMF GenModel you'll
need. Note that if you have mutually dependent Ecore models, they'll
need to be contained by a single GenModel. For one way dependencies,
you can put them in separate GenModels as in the tutorial above.

You'll find you're unable <b>not </b>to do this. No matter which
model you load first, EMF will load all the ones it depends on and will
force you to create a GenModel for them all, or to locate an existing

Dear Ed,
thank you on your answers. I have one more question related to this subject, I need to define BPMN 2 metamodel related to its specification, but in spec. it includes some packages (activity, data, etc.). So, you propse not to put all of these in one file, e.g., bpmn2.ecore, but to have each package in its separate file?

thx, Milan

Milan,
Personally I prefer separate packages. Sometimes people use nested
subpackages, but often that results in subtle issues because it's not so
well tested/used.
