Automatic Conversion of MPEG-7 Specification and Data into RDF(S) For Semantic Interoperability in Information Retrieval

Interoperability between different metadata schemas and data is an important issue for various semantic Web-related applications. The definitions and MPEG-7 data for multimedia content instances can't be used with other metadata standards in a semantically interoperable way. As part of an attempt to build a retrieval system that uses various metadata standards such as MPEG-7 and Dublin Core in a semantic Web environment, we first developed a method for automatically converting the MPEG-7 specification into a RDF schema (RDFS) and MPEG-7 data into RDF data. Our approach is to develop a set of conversion rules for XML Schema definitions into RDF schema definitions, rather than interpreting the semantics of individual components of the MPEG-7 specification
