UML mapping issues for XDE users

The Unified Modeling Language (UML) changed in a number of ways from version 1.4 to version 2.0. While XDE is based on UML 1.4, the Rational® modeling products support UML 2.0. Use this set of topics to understand the more significant differences in UML notation between Rational XDE and the Rational modeling products in the Software Development Platform. The most important changes between these UML versions are in the area of behavioral diagrams; specifically, activity diagrams and sequence diagrams.

The following topics provide a good place to start learning about the differences between UML 1.4 (as implemented by XDE) and UML 2.0; the topics are not meant to be a comprehensive resource that documents every UML notation and implementation difference. For additional information, refer to the UML 2.0 specification and resources on the IBM® developerWorks® Web site.
