MPEG Moving Picture Experts Group a working group of ISO/IEC has developed MPEG-7 “Multimedia Content Description Interface” a standard for describing multimedia content.It addresses a wide variety of media types especially for non-textual documents unlike Dublin Core metadata set for textual documents. The DDL used for MPEG-7 is XML schema for expressing the syntax,structure,datatypes required by MPEG-7.RDF schema used has certain limitations so a specific program hasto be developed which is capable of automatically process an MPEG-7 XML schema document and converting it to some ontology which represents the semantics of MPEG-7 and compatible with corresponding XML schema.
