scope:

This document describes the MPEG-21 Digital Item Declaration technology, which is part 2 of the MPEG-21 standard. This technology is described in three normative clauses: - Model: The Digital Item Declaration Model (clause 6) describes a set of abstract terms and concepts to form a useful model for defining Digital Items. Within this model, a Digital Item is the digital representation of "a work", and as such, it is the thing that is acted upon (managed, described, exchanged, collected, etc.) within the model. - Representation: Clause 7 contains the normative description of the syntax and semantics of each of the Digital Item Declaration elements, as represented in XML. This clause also contains some non-normative examples for illustrative purposes. - Schema: Clause 8 contains the normative XML schema comprising the entire grammar of the Digital Item Declaration representation in XML. In addition, illustrative (non-normative) examples are provided.
