Eclipse 4 Application Model
From OS.bee documentation
Description
OS.bee acts like an Eclipse 4 application, therefore the foundation is the E4 application model.
Figure 1: E4 application model.
OS.bee is not a RCP application but renders on browsers as a web application using the Vaadin framework. To achieve this, a bridging framework works between the E4 application model and Vaadin. The framework is called Vaaclipse.
