The Library of Congress and Xerox will work together to build a repository of around 1 million JPEG 2000 images of public domain works.
Here's an excerpt from the press release:
The two organizations are studying the potential of using the JPEG 2000 format in large repositories of digital cultural heritage materials such as those held by the Library and other federal agencies. The eventual outcome may be leaner, faster systems that institutions around the country can use to store their riches and to make their collections widely accessible.
The project, designed to help develop guidelines and best practices for digital content, is especially relevant to the Library’s National Digital Information Infrastructure and Preservation Program, which has been working with several other federal agencies on digitization standards.
The trial will include up to 1 million digitized, public domain prints, photographs, maps and other content from the Library’s extraordinary collections. Scientists in the Xerox Innovation Group will work with these materials to create an image repository that they will use to develop and test approaches for the management of large image collections.
The images to be used from the Library’s collection are already digitized (primarily in TIFF format), but JPEG 2000, a newer format for representing and compressing images, could make them easier to store, transfer and display. According to Michael Stelmach, manager of Digital Conversion Services in the Library’s Office of Strategic Initiatives, JPEG 2000 holds promise in the areas of visual presentation, simplified file management and decreased storage costs. It offers rich and flexible support for metadata, which can describe the image and provide information on the provenance, intellectual property and technical data relating to the image itself.
Xerox scientists will develop the parameters for converting TIFF files to JPEG 2000 and will build and test the system, then turn over the specifications and best practices to the Library of Congress. The specific outcome will be development of JPEG 2000 profiles, which describe how to use JPEG 2000 most effectively to represent photographic content as well as content digitized from maps. The Library plans to make the results available on a public Web site.
