Do you have the URI for that. I am actually kind of suspicious of, but of course anxious to see, the validity of the approach. Although OMG is trying to avoid being tied with Objected-Oriented. But UML is based on OO, which has a closed-world semantics. I wonder how it can handle the open-world semantics without breaking existing OO paradigm. Xiaoshu
