MPEG-7 is a promising standard for the description of multimedia content. Today, more and more multimedia applications based on MPEG-7 descriptions have been set up for research, commercial and industrial applications. Therefore, an efficient storage solution for large amounts of MPEG-7 descriptions is certainly desirable. However, few existing works focus on a comprehensive MPEG-7 descriptions management system. Although the MPEG-7 descriptions are also the XML documents, the current database solutions for XML documents do not fulfill all the requirements for the management of MPEG-7 descriptions. The goal of this thesis is to investigate the MPEG-7 descriptions storage solution and present the implementation of an MPEG-7 descriptions management system: IXMMS, which is based on RDBMS and ORDBMS. IXMMS is a novel XML storage solution to overcome the problems in the current XML storage solutions for the management of MPEG-7 descriptions. The design of IXMMS pays attention to both multimedia information exchange and multimedia data manipulation. IXMMS introduces two separate databases, one to store MPEG-7 descriptions from the XML perspective, and the other for the low-level multimedia content within the MPEG-7 descriptors. Thus, IXMMS supports the management of MPEG-7 descriptions and MPEG-7 information exchange not only from the XML perspective, but also from the multimedia perspective, and its features can reach the most critical requirements for the MPEG-7 documents storage and management.
