Digital still images are generated, distributed and stored worldwide at an ever increasing rate. Yet, the large number of available metadata description formats prevents consistent and efficient access to image repositories. Standardized solutions for unifying the access and the retrieval of image repositories are therefore strongly needed. The ISO/IEC SC29 WG1 (more commonly known as JPEG) established the JPSearch project, which aims to standardize interfaces of an abstract image retrieval framework. In this context, the paper introduces our contribution consisting of a reference metadata model, which in combination with the JPEG query format improves interoperable image retrieval for users. Second, a transformation rule declaration language for query reformulation is presented, which contributes to interoperability at the repository side.
