Each item type is represented by a separate template: Playlist, Program, Screen, Run.

Each of these templates reads the information provided to keep them, handles the generation of the HTML code and its update, and contains the child elements.

Each item points to its direct parent, but also to the playlist, which points to the playlist.

To make it easier to find items, they are stored by GUID in a dictionary {} in their parent element. In addition, the playlist contains all the GUIDs of its shows, screens and runs.

To find a playlist, a getPlaylist(guidlog) call is made to the pipe.

To find an element of the playlist, it is possible to do a getItem(item,guid) (where item == RUN|SCREEN|PROGRAM|PLAYLIST), but also specific calls getRun(guid), getScreen(guid) or getProgram(guid).
