  Abstract

Recently, XML has been emerging as a standard for storing and exchanging of data for various distributed applications based on the Internet. Since there are increasing demands to store and manage XML documents, a lot of research works are going on this area to develop new tools and techniques based on the XML. However, most of the researches are concentrated on mapping techniques based on instance or DTD, and the main focus is on structural transformation. Current trend of research is toward the usage of XML documents based on XML schema, and demand~ not only conversion of structure but also preservation of the semantic constraints. This paper sets up the using of DlDL standing on the basis of XML schema from MPEG-21 as an application domain, and proposes the mapping model that can preserve semantic constraints in addition. We expand previous research techniques in the preprocessing step for the specific domain, and then, apply various new mapping method~ in the postprocessing step. We present and discuss the system architecture for implementation, and introduce the algorithms and present implementation environment and semantic extension methodology in detail. Finally we show actual table and query processing based on our proposal.
