An Analysis of XML Database Solutions Concerning the Management of MPEG-7 Media Descriptions

MPEG-7 constitutes a promising standard for the description of multimedia content. It can be expected that a lot of applications based on MPEG-7 media descriptions will be set up in the near future. Therefore, means for the adequate management of large amounts of MPEG-7-compliant media descriptions are certainly desirable. Essentially, MPEG-7 media descriptions are XML documents following media description schemes defined with a variant of XML Schema. Thus, it is reasonable to investigate current database solutions for XML documents regarding their suitability for the management of these descriptions. In this paper, we motivate and present critical requirements for the management of MPEG-7 media descriptions and the resulting consequences for XML database solutions. Along these requirements, we discuss current state-of-the-art database solutions for XML documents. The analysis and comparison unveil the limitations of current database solutions with respect to the management of MPEG-7 media descriptions and point the way to the need for new solutions adequate to MPEG-7.
