摘要
A database system stores data relating to media objects and includes a primary metadata table, a supplementary metadata table, a primary content data table, a supplementary content data table, each supplementary content data record being linked to a supplementary metadata record and to a content data record. An object type link table links together records in the primary metadata table, and a content data link table links together records in the primary content data table. An information retrieval system analyses the tables and provides, for a selected instance of an object, information about that object's attributes and relationships with other objects in a hierarchical form.
