Hi Ralph,
we wrote a paper about Chalten last year and it was presented at
ESUG. It has been publish also in the Elsevier "Computer, Languages,
Systems and Structures" journal.... We compared our solution to the one
used by Java and .Net... we also compared it to other more academic
solutions.
There is a pdf with the presentation we gave at ESUG at
http://prog2.vub.ac.be/~cderoove/esugtalks/Wilkinson.pdf
<http://prog2.vub.ac.be/%7Ecderoove/esugtalks/Wilkinson.pdf>
The paper's version publish at Elsevier has more info that the one
presented at ESUG...
We are using the book you mention as the main bibliography.
Thanks for your comments!
Hernan
