The University of Michigan includes JPEG2000 delivery support in DLXS.
DLXS is, in part, a system for providing access to full text, image,
finding aid, and bibliographic content on a large scale.
Specifically, DLXS Image Class uses JPEG2000 to provide access to
continuous tone images like those typically found in museum, visual
resources, and special library collections. Image Class provides robust
cross-collection search and retrieval, along with advanced image
viewing functionality such as zooming. DLXS middleware is distributed
as Open Source, and Image Class can be implemented with the Open Source
database MySQL. DLXS support is available a fee.
DLXS includes unix command line tools for encoding and expanding
JPEG2000 compressed files in the JP2 and JPX formats.
The next release (12) of DLXS adds to Text Class JPEG2000 support for
continuous tone page images.
University of Michigan Image Services (implementation of Image Class)
Below is a specific example of JPEG2000 within Image Class. Note that
the vast majority of the 300,000 images in our system use MrSID, which
is also supported by Image Class. Early in 2004 we began using JPEG2000
for all newly added content.
DLXS uses the Kakadu Software Development Kit for JPEG2000.
