Billions of new images are generated daily. However, the management and exchange of the associated metadata remains cumbersome. Therefore, the Joint Photographic Experts Group (JPEG) has recently promoted a new set of technologies enabling the interoperability between image repositories and/or their clients to an international standard. JPSearch is a suite of specifications that supports the enrichment with metadata data stored in JPEG or JPEG 2000 image formats. It addresses schema and ontology building blocks, a query format, a file format for metadata embedded in image data, and a data interchange format for image repositories.
