Nowadays multimedia data is produced and consumed at an ever increasing rate. Similarly to this trend, diverse storage approaches for multimedia data have been introduced. These observations lead to the fact that distributed and heterogeneous multimedia repositories exist whereas an unified and easy access to the stored multimedia data is not given. In this talk, an architecture, named AIR, will be presented that offers the aformentioned retrieval possibilites. To ensure interoperability, AIR makes use of recently issued standardisation efforts, in names the MPEG Query Format (MPQF) (multimedia query language) and the JPSearch Transformation Rules (metadata interoperability).
