xtUML.org provides the system design community with access to comprehensive UML modeling, execution and translation capabilities through BridgePoint, and a forum to advance the methodology of executable and translatable model-driven development.

Executable, translatable UML (xtUML) is an extension to UML based upon the Shlaer-Mellor Method of Model-Driven Architecture (MDA), which supports a powerful approach to Model-Driven Development (MDD). xtUML.org provides the system design community with access to xtUML editing, execution and translation capabilities, along with a forum to advance the use of this methodology. Find the BridgePoint tool along with models, training materials and community discussion here.
