CE Report on Metadata Adaptation – Integration

This paper reports the results of the CE on MPEG-21 Digital Item Adaptation – Integration defined in document N5182. In the original work plan definition, two main objectives were defined. The first one is to better evaluate if the current DIA Metadata Adaptation tools can fully support the integration of multiple MPEG-7 descriptions of a given content. The second objective of this CE is to evaluate if the current DIA tools allow to disable the metadata adaptation process in order to permit the delivery of “non adapted” content descriptions (e.g. for storage propose). Due to the few time available, only the first goal has been reached. The main contribution of this CE is a preliminary implementation of a metadata integration engine able to adapt Content DI. Based on this implementation, several integration experiments have been conducted to point out which integration tool can be useful.
