What is the data model behind the Multimedia Description Schemes?
The full set of Multimedia Description Schemes, which are related to each other through linking, form a data model or schema for multimedia content description. At both the conceptual- and implementation-levels, the data model is object-oriented and employs modeling principals such as generalization, association, aggregation and spatio-temporal composition. The instantiation of the Description Schemes (DSs) results in description data that is in XML format.
