WP9: A Review of Data and Metadata Standards and Techniques for Representation of Multimedia Content

In the context of the European project MUSCLE (Multimedia Understanding through Semantics, Computation and Learning), a review of data and metadata standards and tools used to represent multimedia (MM) information is presented in this document as the preliminary step necessary to achieve the goals that the project is pursuing. In particular, this report analyses the current data and metadata standards used within the NoE and other MM communities with the aim at exchanging MM information. In the light of the existing state of the art, inside and outside the NoE, it has been also pointed out how the interoperability needs of the NoE (Network of Excellence) can be covered by these standards. A possible strategy for defining a representative metadata model of heterogeneous MM data can also be evicted, taking into account the existing network technologies able to grant semantic mappings and network resource interoperability.
