Executive Summary | JPEG 2000 in Archives and Libraries

Executive Summary | JPEG 2000 in Archives and Libraries:
"For many years, libraries and archives have used the JPEG and TIFF coding standards to store images in an electronic format. These older standards were not designed to integrate the presentation of technical and descriptive metadata associated with images that has become so crucial to long-term usability, nor provide for quick access to these bundles of information. JPEG 2000, named by the Joint Photographic Experts Group, was created to offer these and other significant improvements over the first JPEG standard. In particular, the JPEG committee sought to create an open standard that provided the ability to bundle metadata with images in the same physical file, better efficiency in image compression including the option of “lossless” compression, and storage of multiple resolutions of the same image in one file. The intention of the committee is for JPEG 2000 to replace JPEG as the prevalent standard for storing digital images across many industries and research fields. Although members of the library and archives communities were not explicitly involved with the creation of the new standard, the characteristics of JPEG 2000 files are of great interest. JPEG 2000 is not only an evolutionary progression of formats but also as a revolutionary step that changes best practices in ways that can sustain the profession for a long period of time."
There was also a good program on JPEG 2000 at ALA: http://j2karclib.info/node/65
