EMF Services provides libraries that extend the core EMF framework with additional services or more powerful versions of services provided by EMF itself.
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.
Eclipse PMF focuses in fact on high level presentation modeling concepts on GUI by ignoring the displaying technology artifacts such as appearence, layouts and data binding support.
Visual languages are popular for visualizing concepts and systems. However, just being graphical in nature does not automatically make a diagram easy to understand. Its usefulness much rather depends on the placement of its elements, that is: on its layout. Getting the layout right is labour intensive and time consuming and can be made a lot easier by making algorithms do the work. The Eclipse Layout Kernel (ELK) provides such layout algorithms, as well as an infrastructure to connect them to diagram editors.
