Model and Usage of a Core Module for Axmedis/MPEG-21 Content Manipulation Tools

Despite the relevance of the MPEG-21 standard, little has been done about the modeling of authoring tools and players for the production/consumption of MPEG-21 digital objects. The design and implementation of MPEG-21 tools present several critical points to be solved at the architectural level, so as to ensure security and provide a suitable support and the requested flexibility for manipulating any kind of digital resource, according to the spirit of MPEG-21 standard. This paper presents the AXMEDIS core model and components for MPEG-21 content authoring tools and players. The proposed architecture provides both data manipulation flexibility and a high level of security when digital resources are used. The same architecture can be used to develop any other MPEG-21 DI tools. The architecture presented has been adopted to build authoring and player tools developed for the AXMEDIS IST FP6 R&D European Commission project
