The JPEG2000 in Archives and Libraries Interest Group of the LITA division of ALA is pleased to present a program on Archiving in Practice with JPEG2000 on Sunday, June 29th from 8am to 10am in Ballroom E, Anaheim Convention Center.

Lead Presentation

Mr. Justin Dávila, Digital Media Workflow, Business and Technology Consultant, will start the program with an overview of the JPEG2000 technology followed by a review of projects that use JPEG2000 for still and moving images. Special emphasis will be placed on the concept of "visually lossless" compression -- a middle-ground between mathematically lossless compression and lossy compression. Projects and technologies to be reviewed include the Dance Heritage Coalition, Library of Congress, National Institute of Health/National Library of Medicine, and the Sony 4k Digital Cinema Projectors.

JPEG2000 Lightning Talks

Following Mr. Dávila's presentation, members of the audience are invited to contribute to the discussion by presenting 5-minute "lightning talks" on a project or technology in the cultural heritage arena. The "lightning talk" format is an adaptation of the "unconference" meeting style. The concept is to have self-selected presenters talk on a topic of interest to the audience for no more than five minutes at a time. The goal is to give an inch deep and mile wide perspective on topics that can be the start of follow-up conversations among the presenters and members of the audience.

Due to the quick nature of the lightning talk format, presenters are strongly encouraged to bring presentation materials on a USB flash drive or download them from the web to avoid the complications of laptop switching. It is anticipated that wireless access will be available in the meeting room.

Suggested topics include:

• Descriptions of other visually lossless experiments or extended comments on the topic
• Overview of a project using JPEG2000 as an archival master format
• Overview of a project using JPEG2000 as an access master format (using some other format as an archive master)
• Advantages and Disadvantages of embedding metadata into the JPEG2000 file
• Tests of quantitative measurements of JPEG2000 quality
• Use of Motion JPEG2000 in the cultural heritage arena
• Differences between JPEG2000 Part 1 (JP2) and Part 2 (JPX), and the complications of proprietary color profiles
