Hi Every One...
I have loaded a meta model i.e trip.ecore Programmatically (using resourse set, Resourse etc). Thereafter, I created instances of the Meta-Model Classes using EFactory. Instances are successfully created and i have stored them in xmi model.
Now Iam facing issues in setting values of these attributes, programmatically. and setting links among these instances programmatically.
like i have created an instance Trip, now i want to set the value of its attruibute name of type estring as "London Trip" How will i do that programmatically and not using xmi editor.

EObject Trip = tripFactory.create((EClass) tripPackage.getEClassifiers().get(1));

Object is made how will i access its attributes and references....

Trip._____________
Thanks in advance

Hi Yawar,

Did you generate the code(model, edit, editor) from your trip.genmodel ?
After deployment of the resulting plugins (or in a runtime), you would have the possibility to use:

Trip myTrip = TripFactory.eINSTANCE.createTrip();
myTrip.setName("London Trip");
...

For the moment I assume you have dynamic instances, you might try : trip.eSet(EStructuralFeature feature, Object newValue);

For those general question on Ecore and not related to Sirius, I invite you to post on the EMF forum: https://www.eclipse.org/forums/index.php?t=thread&frm_id=108

You might also find resources on the following page: https://www.eclipse.org/modeling/emf/docs/
