Via Antony Theobald's message, the U.K.'s Digital Preservation Coalition and the British Library will be holding a workshop in June on JPEG2000. From the workshop announcement page:

This forum will look more into the details of the standard and expert speakers who are familiar with the standard or have implemented it will share their experiences. The forum will also include industry experts to talk about the creation of the file formats. Delegates will learn about the benefits of the standard, especially with regard to digital preservation and whether it is worth implementing it within their own institutions as an image storage format. Guest speakers include Bill Comstock, Harvard College Library, Christoph Becker, Vienna University of Technology, Manfred Thaller, Cologne University and Jim King, Adobe.

An August 1, 2005 invitational meeting gathered about fifty archivists and technologists involved in the long term preservation of videos and films. The meeting, "Getting to Disk-based Lossless Digital Video Compression", was hosted by the U.S. National Library of Medicine, itself much involved in moving image preservation.

Participants considered the potential of lossless, on-disk video storage in light of the "twilight of tape" as a cost-effective storage media. Other speakers reviewed current video metadata standards, and recent work in automatic extraction of metadata from video. The meeting included the first public demonstration of real-time, full-screen, mathematically-lossless video compression and decompression based on the Motion JPEG 2000 (MJ2) standard.

Heard during the Google and Libraries: What’s in Store for Google Print and Google Scholar presentation at ALA: participating libraries can receive either G4 TIFF or JPEG 2000 image files for the scanned books. No word yet as to whether they are JP2s, JPXs, or JPMs...

For many years, libraries and archives have used the JPEG and TIFF coding standards to store and make available images in an electronic format. Decades of research in image compression techniques as a subfield of signal processing have yielded advancements through the use of wavelet transformation (as opposed to JPEG which uses discrete cosine transformation and various competing standards for TIFF compression), and some have adopted products based on proprietary wavelet compression implementations such as SID. In the 1990s, under the auspices of the International Standards Organization and the standards section of the International Telecommunication Union, the Joint Photographic Experts Group worked to create a new imaging standard using wavelet compression. The work of the committee reached a pinnacle in December 2000 with the ratification of Part 1 of the JPEG 2000 standard.

The symposium organizers view JPEG 2000 as both an evolutionary progression of formats and a revolutionary step in the advancement of best practices that will sustain the library and archive communities for a long period of time. On November 4-5, 2004, the invited speakers and delegates considered the adoption of the JPEG 2000 standard by libraries and archives. The symposium was arranged in an arc to take delegates from little assumed knowledge of the JPEG 2000 standard, through an awareness of how it can be used, to a point where a discussion could occur on stewarding the critical aspects of the standard. The result was a dialog that started the process of the adoption of this important standard into best practices, products, and services that meet the unique needs of the library and archive communities.
