Meeting of the JPEG 2000 Interest Group on Jan 14th in Philadelphia

The JPEG2000 in Archives and Libraries Interest Group met on Saturday afternoon. 11 people attended the meeting. In the information sharing part of the meeting, there was discussion of the benefits, drawbacks, and considerations of “visually lossless” versus “digitally lossless”. In particular, one of the attendees talked about how the Internet Archive had chosen to go with visually lossless J2K files after extensive testing and review. (This attendee was not from the Internet Archive, but knew about its project.)

Some ideas for subsequent programming could be a review of J2K tools and a discussion of how much metadata is appropriate to put in the JP2/JPX file format metadata boxes.

The IG is preparing a program on using JPEG2000 for preservation for the Annual meeting in Anaheim. The description of the program was revised to:

The JPEG2000 image file format has made modest progress as an access master in cultural heritage application. Its acceptance as a preservation master format has been necessarily more cautious and deliberate. Panelists in this program will offer perspectives for using the JPEG2000 standard for preservation of still and moving image archives. Participants will learn the advantages and disadvantages of JPEG2000 as a preservation format and gain an understanding of trade-offs in the parameters that the specification offers.

Billy Kwan was also mentioned the options for online courses using ALA’s new Moodle system. At this time, the j2kIG doesn’t have any plans to take advantage of that, but the chair will put it on the agenda for the IG’s business meeting in Anaheim. The j2kIG interest group is also up for renewal this year, and is working through the paperwork. In that process, the attendees at this meeting selected Peter Murray from OhioLINK to continue as chair and Nick Baker from Williams College to be vice-chair.
