For any activity, the elementary digital documents are ‘clips’ of three types: album, text, video.

Clips are created and edited in the Clip Manager, from the Admin menu.

The engine for networks-of-stories allows one to build a personal sequence to explore and play the clips of the story, according to the sequence triggered by the personal curiosity and interest of the user.

The personal path is recorded and then retrieved by the user. Clips may also be viewed according to their main subjects. Metadata, texts and images of each clip can be printed.

When the specific engines will be developed, the contents of the clips will be also be re-used online for creating other activities, such as timelines, maps, or serious games.
