ABSTRACT
The MPEG-7 standard provides description mechanisms
and taxonomy management for multimedia documents.
There are several approaches to design a multimedia database
system using MPEG-7 descriptors. We discuss two of
them: relational databases and native XML databases. We
have implemented a search and retrieval application for
MPEG-7 descriptions based on the latter.
1. INTRODUCTION
Multimedia metadata information represents -from the
service providers’ point of view- a nice way to add value
to multimedia resources (i.e audiovisual files) distribution.
Managing audiovisual essence implies to structure its associated
metadata and content-based descriptors; using description
schemes, taxonomies and ontologies, to organize
a meaningful data knowledge representation.
MPEG-7 standard provides content description for audiovisual
content, defining normative elements as Descriptors,
Description Schemes and a Description Definition
Language (DDL). The main use of MPEG-7 standard is,
then, to describe all the information of multimedia assets.
In that context, we usually talk about metadata (that is
data about data) and, in that particular case, data about
the multimedia information that is described. Thus, creating
MPEG-7 documents allow a…
