For example, a UML profile for Analysis can assign appropriate semantics to the UML constructs. Robert's idea is a good one. I hope you will agree, Robert, that first, or in parallel, we need to remove some of the restrictions from UML. ... This is an invitation to anyone interested to participate in the communityUML process. The process is very slowly getting started at: http://uml.fsarch.com This web site is editable by: you. ... A story about profiles: The UML does not allow interfaces on objects. Of course, the essence of the OMG model is that an object has an interface. So the folks who prepared the UML profile for CORBA had to use a hack. The could not use UML interface to represent CORBA interface, so they used a stereotyped UML class to represent an interface. That is an example of why i feel it is important to get UML in a state where it is open to several different ways. Then we can have a UML profile for folks who like the UML the way it is. And others for others. Cordially, Joaquin ................................................
