5 Adding Formal Semantics to MPEG-7

MPEG-7 specifies the connection between semantic annotations and parts of media assets. We take it as a base of knowledge that needs to be expressible in our ontology. Therefore, we re-engineer MPEG-7 according to the intended semantics of the written standard. We satisfy our semantic interoperability not by aligning our ontology to the XML Schema definition of MPEG-7, but by providing a formal semantics for MPEG-7. We use a methodology based on a foundational, or top level, ontology as a basis for designing COMM (cf. Chapter “Ontology Engineering Methodology”). This provides a domain independent vocabulary that explicitly includes formal definitions of foundational categories, such as processes or physical objects, and eases the linkage of domain-specific ontologies because of the shared definitions of top level concepts. We briefly introduce our chosen foundational ontology in Sect. 5.1, and then present our multimedia ontology, COMM, in Sects. 5.2 and 5.3. Finally, we discuss why our ontology satisfies all our stated requirements in Sect. 5.4.
