Like a CD package, each DDA has album tracks, lyrics, liner notes/credits, photos and artwork. Unlike a CD package, a DDA can have hundreds of tracks (over varied file formats) and thousands of photos.
The DDA owner also gets their own space within the D:Net Media System - myDDA. Not just a back up of each user’s content, myDDA is a means to acquire new content, and access the content they own, from any Internet-enabled computer.
The format was announced on 1 December 2008.
