Can you give an example of a Digital Item?

Standard: 

One very simple example of a Digital Item would be a ‘digital music release’: It could comprise two sound recordings (e.g. sound files coded in MPEG-2 AAC), the cover photograph (using JPEG), a video clip, and a text file containing the lyrics for the songs. The Digital Item could also contain metadata describing the content of the Item.

The structure of the Digital Item allows the User (or the User’s device) to make choices and selections of components within the Digital Item, for example based on his preferences or capabilities (for example if the User wants to transfer the aforementioned music release to a simple portable music player, the terminal would choose to not transfer the video clip onto the device).
