This one is a little newer

http://eclipsesource.com/blogs/tutorials/emf-tutorial/

You can always substitute your own model for one in a tutorial.

Thank you so much. Actually, I'm a beginner in using EMF and i wonder if this could help me to know how to use reflective interfaces, i had an idea about them and i need to use them in my application where i found a piece of code in a book but it isn't mentioned how to recuperate the references of package and factory ( first and second line, just comments)

[1] EFactory fact = //obtention de la référence
[2] EPackage pa = //obtention de la référence
[3] EClass acEC = (EClass) pa.getEClassifier("Acteur");
[4] EObject ac = fact.create(acEC);
[5] ac.eSet(acEC.getEStructuralFeature("nom") , "Client");
[6] EClass cuEC = (EClass) pa.getEClassifier("CasdUtilisation");
[7] EObject cu1 = fact.create(cuEC);
[8] cu1.eSet(cuEC.getEStructuralFeature("intitulé") , "Commander Panier");
[9] EObject cu2 = fact.create(cuEC);
[10] cu1.eSet(cuEC.getEStructuralFeature("intitulé") , "Valider Panier");

When i did a search i was directed to the tutoial that i asked about. So i really appreciate if you indicate me the tutorials i have to read and how to recuperate that references.

Of course the EMF book is the most complete reference. There's all the
documentation on this page:

https://www.eclipse.org/modeling/emf/docs/

This might help a bit

http://www.ibm.com/developerworks/library/os-eclipse-dynamicemf/

Also the code in EcoreUtil illustrates many use cases for reflective access.

If you know which package/factory it is, you can just use
"Packagename"Factory.eINSTANCE and "Packagename"Package.eINSTANCE. Also,
there is "Packagename"Package.Literals which has constant interface
fields for all the elements in the package.

If you do not know the package, but the package uri namespace
identifier, you can look it up in the package registry:

EPackage.Registry.INSTANCE.getEPackage()/getEFactory()
