2. WPEFramework

WPEFramework provides a unified web-based interface with a consistent navigation model. In this model, plugins (custom or generic) are controlled and queried, through the WPEFramework application.

   /usr/bin/WPEFramework-1.0.0000000
   /usr/bin/WPEProcess -> WPEProcess-1.0.0000000 (each out-of-process plugin will run in a seperate WPEProcess)
   /usr/bin/WPEProcess-1.0.0000000
   /usr/bin/WPEcdmiWPEFramework -> WPEFramework-1.0.0000000 (main WPEFramework process, started with systemd, Controller and in-process plugins run in this process)

...

WPEFramework runs as a systemd service. The main process is named WPEcdmi (it needs to be renamed to WPEFramework ) and runs the main controller plugin as well as the other in-process plugins (such as monitor, tracing etc).

8. WebKitBrowser plugin & rdkbrowser2

WebKitBrowserPlugin allows WPEFramework clients to launch WPE instances, set the URL, suspend&resume browser processes. It works similar to rdkbrowser2 but instead of the rtRemote interface, HTTP API is used.
