MPEG-7 and MPEG Query Format (MPQF) are two related standards developed by the Moving Picture Experts Group (MPEG) to address the multimedia retrieval problem. MPEG-7 aims to provide standardized comprehensive set of tools for description of audiovisual content, while MPQF aims to provide a standardized interface which unifies the retrieval over different multimedia repositories. However, both standards have some limitations. On one hand, MPEG-7 is based on XML Schema, therefore, does not have formal semantics, which makes difficult to be managed by computers.
