Semantic Interoperability in Digital Library Systems

This report is a state-of-the-art overview of activities and research being undertaken in areas relating to semantic interoperability in digital library systems. It has been undertaken as part of the cluster activity of WP5: Knowledge Extraction and Semantic Interoperability (KESI). The authors and contributors draw on the research expertise and experience of a number of organisations (UKOLN, ICS-FORTH, NETLAB, TUC-MUSIC, University of Glamorgan) as well as several work-packages (WP5: Knowledge Extraction and Semantic Interoperability; WP3: Audio-Visual and Non-traditional Objects) within the DELOS2 NoE. In addition, a workshop was held [KESI Workshop Sept. 2004] (co-located with ECDL 2004) in order to provide a forum for the discussion of issues relevant to the topic of this report. We are grateful to those who participated in the forum and for their valuable comments, which have helped to shape this report. Definitions of interoperability, syntactic interoperability and semantic interoperability are presented noting that semantic interoperability is very much about matching concepts as a basis. The NSF Post Digital Libraries Futures Workshop: Wave of the Future [NSF Workshop] has identified semantic interoperability as being of primary importance in digital library research

Deliverable D2.2 Specification of lightweight metadata models for multimedia annotation

This deliverable presents a state-of-art and requirements analysis report for the LinkedTV metadata model as part of the WP2 of the LinkedTV project. More precisely, we first provide a comprehensive overview of numerous multimedia metadata formats and standards that have been proposed by various communities: broadcast industry, multimedia analysis industry, news and photo industry, web community, etc. Then, we derive a number of requirements for a LinkedTV metadata model. Next, we present what will be the LinkedTV metadata ontology, a set of built-in classes and properties added to a number of well-used vocabularies for representing the different metadata dimensions used in LinkedTV, namely: legacy metadata covering both broadcast information in the wide sense and content metadata and multimedia analysis results at a very fine grained level. We finally provide a set of useful SPARQL queries that have been evaluated in order to show the usefulness and expressivity of our proposed ontology
