How to get the ECore internal details [message #416653]

Hello All,
I am using EMF and i am having a rose class model.
But I want to know why EMF is generating the ecore model and genmodel
both.

What is that ecore(metamodel) internally.mean to say internals of ecore.
can i generate my code without ecore mean to say withonly genmodel or can
I be able to generate my code without genmodel mean to say without ecore.

Can any body provide me any link which gives the internals of ecore.and
also links for the transformation(how it is getting converted from UML to
ecore metadata.)

Thanks in advance
Debasis

Hi Debasis,

The Ecore model (.ecore file) is the real EMF representation of your
model. The generator model (.genmodel file) decorates it with details
related only to code generation.

The two artifacts contain different information, and both are required
to generate code.

I would start with the EMF Overview:

http://help.eclipse.org/help33/topic/org.eclipse.emf.doc/ref erences/overview/EMF.html

For more details on the internals of EMF, you should check out the rough
cut of our book:

Hi Dave,
Thanks a lot for a quick reply.I have gone through all ECore key types
and ECore hierarchy.

Could you please provide me some good reference material to know how the
transformation(transformation design architecture) is happening
(from UML to ECore).

Thanks in advance
Debasis

Hi again Debasis,

The mapping from UML to Ecore is described in detail in the EMF book.
The internals of the implementation are not documented anywhere.

You'll find the code in org.eclipse.emf.importer.rose.RoseEcoreBuilder,
with support from classes in the org.eclipse.emf.importer.rose.builder
package.

Cheers,
Dave

Hi Dave,

Thanks a lot for the reply.could you please tell me the algorithm of the
transformation from UML to ECore.

Thanks in advance

Hi Debasis,

As Dave said, the algorithm is implemented in RoseEcoreBuilder and
carefully detailed in the book. You will also find a lot of information
at the following presentation available in our documentation page
(http://www.eclipse.org/modeling/emf/docs/):
http://www.eclipse.org/modeling/emf/docs/presentations/OOPSL A/OOPSLA_2006_T38_Intro_To_EMF.pdf

Cheers,
Marcelo
