@flavia, I never got as far as building an administrative UI for this. As a placeholder I had the activator for that module automatically configure and create based on the CIEL dictionary, which you can see here:
In other words if you have the CIEL dictionary installed, and then you start this module, it should autocreate the frequencies for you.
The correct approach would be to have a screen that lets the administrator manage their list of frequencies, and also to configure the
frequencyPerDay field, which I skipped.
