AXMEDIS tool core for MPEG-21 authoring/playing

Despite to the relevance of the MPEG-21 standard, little has been done by the collectivity about the modeling of authoring tools for the production of MPEG-21 digital objects. The designs and implementation of an MPEG-21 authoring tool presents several critical points to be solved at the architectural level. This paper presents the AXMEDIS tool core for MPEG-21 content authoring and playing. The architecture identified and proposed supports both data manipulation flexibility and a high level of security when digital resources are used. The same architecture can be used for structuring other MPEG-21 players. The architecture presented has been adopted to build authoring and player tools developed for the AXMEDIS IST FP6 R&D project.
