This is a summary of the discussions of the participants at the interest group meeting during the ALA Annual Conference 2007 in Washington DC.

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.
