In a preferred embodiment, the UI change routine includes the step of executing the UI inventory routine. In a preferred embodiment, the step of executing the UI inventory routine is performed after the step of selecting a media ID. In a preferred embodiment, the media ID selected during the step of selecting the media ID influences the formation of the inventory criterion. In a preferred embodiment, the UI provides that, for a selected media ID which is assigned to a specific series, the inventory criterion is selected such that when it is used in the inventory routine of a server, all the identifiers stored in the server's identifier table are read, which are assigned in the identifier table to a specific user or a user group to which the specific user belongs according to the server's user group table, and to which a specific identifier type is assigned in the identifier table, namely the identifier type associated with the specific series. With this version, the user is only offered to select his/her identifiers in the GUI that belong to the series of the selected media ID. For example, if the user has selected a sequence of the series “Benjamin Blümchen”? as the media ID, the inventory criterion can be selected in such a way that the inventory signal only contains identifiers that are assigned to the series “Benjamin Blümchen”?.
In a preferred embodiment, the UI inventory routine and/or the UI change routine has the step of selecting an identifier. With the step of selecting an identifier, the user selects an identifier within the UI, which becomes part of the change signal in the course of executing the UI change routine.
