Toward a scalable multimedia metadata infrastructure using distributed computing and semantic web technologies

This paper describes a research activity carried on in the frame of a collaboration among ISTI-CNR, leader of the ´Representation and Communication of Data and Metadata´ Workpackage in the European Project MUSCLE-NoE (´Multimedia Understanding through Semantics, Computation and Learning Network of Excellence´) and the Dept. of Electronics, A.I. & Telecommunications of the Polytechnic University of Marche. In particular, an original approach towards multimedia metadata handling and a solution for massive metadata processing, based on distributed computing, are presented. Besides, a tool kit that glues low level metadata with higher-level representation capabilities of RDF is also approached.
