I attended the second half of Raphael Troncy and Lynda Hardman’s excellent tutorial on the importance of using metadata to semantically describe multimedia content. The technique they presented attaches metadata to the multimedia content it describes and thus enable users to reuse and repurpose this previously published content for their own needs.

Raphael introduced the audience to the Core Ontology for Multimedia (COMM), which they have been using to annotate different types of multimedia. Both Raphael and Lynda stressed the importance of linking these annotations together with other data sets which can only be achieved by using Resource URI’s rather than Literals wherever it is possible to. This certainly resonates with the research that Rob, Danny and myself documented in our Semantic MARC Paper, where we came to the same conclusion.

Raphael and Lynda also introduced the audience to the K-Space Annotation Tool which has been implemented to allow people to easily annotate multimedia content. Once multimedia is annotated you can build some impressive applications that can navigate this graph of linked data.
