A Multimedia Digital Library System Based on MPEG-7 and XQuery

چکیده
We designed and implemented a digital library system that supports content-based retrieval of multimedia objects based on MPEG-7 and XQuery. MPEG-7, a metadata standard for multimedia objects, can describe various features such as color histograms of images and content descriptors. As such, a multimedia digital library system built with MPEG-7 metadata can provide content-based search for multimedia objects. Since MPEG-7 is defined by XML schema, XQuery was a natural choice as a query language. By adapting the standards, MPEG-7 and XQuery, our system has benefited for interoperability. First, any MPEG-7 metadata instance can be accommodated into the system with no additional effort. Second, any system that can generate an XQuery can retrieve necessary information. Third, our system can be easily extended to support any XML documents. Currently we have developed a prototype system for retrieving images of Korean cultural heritage.

Queries of Digital Content Descriptions in MPEG-7 and MPEG-21 XML documents
The emerging ISO/IEC MPEG-7 and MPEG-21 multimedia standards use XML Schema for digital content descriptions and digital item declarations. They have posed an interesting challenge to XML query language design. The paper shows certain critical query specification issues for MPEG-7 and MPEG-21 XML documents and illustrates a logic method to handle the limitations in current text-oriented XML que...

MPEG-7 (Multimedia Content Description Interface) is a standard for describing the content of multimedia data and adopts XML (eXtensible Markup Language) Schema as its Description Definition Language. However, as a forthcoming standard for querying XML data/documents, XQuery (XML Query Language) has weakness in the query of vector-based feature described in MPEG-7. Thus, we propose an extension...

MPEG-7 is a promising standard for the description of multimedia content. A number of applications based on MPEG-7 media 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. As a kind of data-centric XML documents, MPEG-7 descriptions can be stored in the rela...
