Eclipse Capra is a traceability management tool. It allows the creation of trace links between arbitrary artefacts, provides features to edit them and keep them consistent, and visualise the relationships between them.
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.
