Hello all,
I'm just wondering if there is an actual difference between those two
annotations for eClass definition?
Btw, could someone give me an uptodate and comprehensive reference for
all the available annotations?

thx,
Serge.

For both questions, you're well off with the addison&wesley book
"eclipse modeling framework" by the same authors of EMF. In the book,
page 115 and following list what you need
( http://print.google.com/print?id=ff-9ZYhvPwwC&pg=PA117&a mp;lpg=PA117&dq=java+specification+for+classes+eclass&am p;prev=http://books.google.com/books%3Fq%3Djava%2Bspecificat ion%2Bfor%2Bclasses%2Beclass&sig=VEpT7FdXdEaO5G0hBf1pRhb iBIo&auth=DQAAAGwAAADT-yv3VJfm5pDYhjAHCaMsib6aY2a6utT5wg 5cepkYdMZVE4Pk00pfBUVqC_DsV7qvXMVIBZnCylnrqeXHkb34f1-44G6as2 voBcGMAG3Mx-NijR0BN5lSmeVtHrh-ZBnhBk2lVHexSbipRfTLqkjj)

Serge,

Yes, the book is the place to go. We're updating that chapter for the
next version of the new book with the new things we've added since 1.x.

With regard to your specific question, something marked as an interface
will generate only an interface but no Impl class; something marked as
abstract will generate both an interface and an Impl class where the
Impl class will be abstract and hence there will be no factory method to
create instances of it.
