Eclipse Papyrus-xtUML is a tool which supplies the capability to edit, execute and translate xtUML models. 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). Papyrus-xtUML 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.
The Eclipse OMR project consists of a highly integrated set of open source C and C++ components that can be used to build robust language runtimes that will support many different hardware and operating system platforms. These components include but are not limited to: memory management, threading, platform port (abstraction) library, diagnostic file support, monitoring support, garbage collection, and native Just In Time compilation.
