The OpenEngSB project also maintenance several sub-projects. Those are mostly for showing some use cases of the OpenEngSB and implementing some of the extended concepts. In addition we try to “eat our own dog food” as much as possible; e.g. using OpenCIT for our internal project builds http://build.openengsb.org
Those links show a complete set of applications based on the OpenEngSB and using it's advantages.
This is a collection of libraries developed by the OpenEngSB team for the OpenEngSB, but independent of the core project. Those are required to activate various features, but not are not located at the core.
