What is a Digital Item?


Digital Items are structured digital objects, including a standard representation and identification, and metadata. They are the basic unit of transaction in the MPEG-21 framework.

Basically, a Digital Item is a combination of resources (such as videos, audio tracks, images, etc), metadata (such as MPEG-7 descriptors), and structure (describing the relationship between resources).
