How do I declare a Digital Item?


Digital Items are declared using the Digital Item Declaration Language (DIDL). Declaring a Digital Item involves specifying its resources, metadata and their interrelationships.

The DIDL is a language based on an XML schema that has developed to allow the declaration of Digital Items within MPEG-21. It is a flexible and general schema that provides the hooks for higher-level functionality.
