I picked up this book at the bookstore about 10 days ago, and have read through about half of it. I was not aware of the EMF before this, and proceeded to download the missing parts needed for using this with eclipse.
Most of the authors work for IBM - the origin of Eclipse, and the design of what they have done looks very clean - It will take some real working with before I can feel comfortable with though.
At least in the first half of the book, the ties of Java-XML- and UML are explained and how the Model ties them together with their own XML called Ecore for capturing the model. I have started to see the design picture which makes sense so far - and the ability to use a simple set of UML makes sense.
It does seem that the current status of EMF is an early stage, and has room to grow - which they state will be slow steps-which is probably a good way to approach this.
I am very intrigued with the idea of the code generation, and once I get the time to sit down with it in a working mode I can comment better on its effectiveness.
