Good stuff, Phil. I saw the announcement of y’all’s work, but didn’t have a chance to blog pointers to it. Thank you for doing so (both for the work and for telling us about it!).

Just a quick note, at the Biodiversity Heritage Library [http://www.biodiversitylibrary.org/] we are now serving all page images via djatoka [http://biodiversitylibrary.blogspot.com/2009/01/now-serving-all-page-images-via-djatoka.html]. Also, I have written a detailed breakout of the architecture I’ve designed to provide this service on my blog [http://www.fak3r.com/2009/01/27/howto-serve-jpeg2000-images-with-a-scalable-infrastructure/]

So far djatoka, has been tremendous, it’s stable, fast and was easy to implement. The only thing that took time was the reworking of the viewer, our dev reworked the newer iipviewer with mootools (code release forthcoming) to function more like our old viewer.

Thanks

Phil

Ron — I hope interest now starts in earnest around JPEG2000 as an access format now that an open source, web based viewing engine is now available. Then institutions can really start to see that a very good access format is also a very good preservation format.

anon — I believe djatoka is using a freely redistributable compiled Kakadu library. So while Kakadu is not open source itself, its use here as a compiled library is within bounds of most definitions of “open source”.

Thsi is slightly misleading, because the Kakakdu software is not open source software.

The Library of Congress Preservation Directorate’s Digital Preservation laboratory has – in anticipation of this critical Cultural Heritage community development – been investigating methods for determining JPEG 2000 quality encoding settings for a range of image content and use.

If parties reading this post want to start an online discussion along those lines on the Jester, please respond here. A potential venue for this discussion is the JPEG 2000 in Archives and Libraries website –>> http://j2karclib.info/

That site has been around for around five years now, but should now see increased activity as a function of interest in djatoka.
