You can't really configure a dataengine. By design they're meant to be
separated from where they're being used, and in general are read only.

You could combine it with a Plasma::Service to set data that writes to it's
own config file then updates the dataengine.

Native QML Plugins can be used directly instead of going via dataengines.
The notes applet might be a good example as that contains some session-wide
objects.
