An implementation of MPEG Query Format over relational-based multimedia database

The MPEG Query Format (MPQF) which MPEG Group is developing is to standardize query interface for XML-based multimedia retrieval systems. However MPQF is not directly supported by any database products including native XML database and relational database. Since relational databases such as Oracle, DB2 and MS SQL Server are still the mainstream database products in practice to store multimedia data such as MPEG-7 and Dublin Core XML document, this paper aims to propose a method to translate an MPQF query to SQL that relational-based multimedia database can evaluate and execute.
