> The Biodiversity Heritage Library (BHL) has integrated djatoka, the
> new
> open source JPEG 2000 image server developed by Ryan Chute and Herbert
> Van de Sompel at Los Alamos National Laboratory, into its production
> portal at http://www.biodiversitylibrary.org. BHL is a consortium of
> natural history libraries who are partnering with Internet Archive to
> digitize public domain scientific literature of use to individual
> scholars and large bioinformatics projects like the Encyclopedia of
> Life. To date more than 27,000 volumes have been made available in
> open
> access through Internet Archive and the BHL Portal.

> Since last Thursday (Jan 22), djatoka has been serving the images for
> the (nearly) 11 million pages available through BHL. It's scaling &
> performing well under our normal load of 1,500 users per day, but we
> wanted to give it a more robust test...which we're hoping to see with
> this e-mail post to various listservs. We've written a blog post with

> We also wanted to make this announcement in support of djatoka and
> JPEG
> 2000, given the recent survey of JPEG 2000 implementation in
> libraries,
> available at http://digitalcommons.uconn.edu/libr_pubs/16/. In short,
> our experience evaluating and implementing djatoka has been extremely
> smooth and we were able to drop it into our existing infrastructure
> and
> UI with a minimum of customization (as described in the post). It
> replaces a non-scalable, proprietary JPEG 2000 image server that until
> now has been the biggest bottleneck in delivering our content to
> users.
> The lack of open source options for JPEG 2000 delivery is often among
> the most frequently cited reasons why cultural heritage organizations
> have not embraced the JPEG 2000 format. Hopefully our positive
> experience implementing djatoka and its demonstrated use within BHL
> can
> be a stimulus for other projects to evaluate the software and/or put
> JPEG 2000 back in consideration as a delivery format.
