Multimedia metadata mapping: towards helping developers in their integration task

The recent growth of multimedia in our lives requires an extensive use of metadata for multimedia management. Consequently, many metadata standards have appeared. Using these standards has become very complicated since they have been developed by independent communities. The content and context are usually described using several metadata standards. Accordingly, a multimedia user must be able to interpret all these standards. In this context, several metadata integration techniques have been proposed in order to deal with this challenge. These integrations are made by domain experts which is costly and time-consuming. This paper presents a new system for a semi-automatic integration of multimedia metadata. This system will automatically map between metadata needed by the user and those encoded in different formats. The integration process makes use of several types of information: XML Schema entity names, their corresponding comments as well as the hierarchical features of XML Schema. Our experimental results demonstrate the integration benefits of the proposed system.
