In a concurrent modeling environment, how does the change on one client is reflected to another? What kind of information is exchanged between the clients?

CDO simply produces standard EMF notifications just as if the model was
directly modified on that client. The information for those
notifications is transmitted by the server to the client under the covers.

The server is not notified. Clients send commit requests (and other requests) to the server.

I need know more about these EMF notifications. These notifications are some sort of XML model differences sent to the client?

Please read the Javadocs. The EMF book is an excellent source for information, too.
