For my language, I begin to write all my grammar rules in xtext,
This grammar generate an ecore file which is the meta-model of my grammar.
But, for the b3, I have the impression that the meta-model (ecore file) was created first. and no one rule in the grammar generate an ecore class.
(all rule in the grammar return an EObject of the meta-model).

Why have you chosen this method? What are the advantages of this method?

I started by generating the model from the grammar. This is good as it
is a convenient way to explore ways to write the grammar.

When having a decent grammar, the model becomes API, and you don't want
it to change in mysterious ways when doing "bad" things in the grammar.

You also have a lot more control over the grammar that way.
