XModel defines a UML Profile, i.e. a set of Stereotypes, to annotate UML class models. It also defines a structured set of properties, to be associated to models classes as well as stereotypes and an additional evaluation semantic for these properties.
XModel is currently only available to customers of Sphenon's EM/OS system. That might change in the context of our Open Source initiative, but there is no guarantee that it will happen.
