DLXS Middleware: 50 MB to store the libraries and programs that make up the working DLXS system.
Content: This varies dramatically according to the amount and format of your material. For a collection of significant scale, the storage requirements will be dominated by the number of page images and/or continuous tone images--SGML and metadata are quite small in comparison. DLXS allows you to store the middleware and the content in different locations to simplify system administration.

Root access (to change aspects of the environment, e.g., directory and file permissions, web server configuration, etc.)
A web server that supports Apache sessions. We recommend Apache 1.3.34 or higher.
OpenSP 1.5 or higher (for using the supplied tools to prepare SGML and/or XML content for delivery via DLXS).
Perl 5.8.8 or higher.
The following Perl modules that are not part of the base Perl distribution (where versions are given, DLXS requires that version or higher). Note that XML::LibXML and XML::LibXSLT are now required for all classes except BibClass. Currently, the BibClass user interface is not based on XSL. We recommend these Perl modules be installed before you begin the DLXS installation process.

MySQL version 4.1 for Image Class metadata, for storing session data and for Collmgr collection data. MySQL command line client must also be version 4.1 or newer. For some useful MySQL tips in a Solaris environment, see Installing DLXS Version 13 on Solaris 10

c42pdf for displaying TIFF images in PDF format (free)
tif2web for displaying TIFF images in GIF and/or PNG format (free). Note that we distribute the Linux and Solaris binaries for tif2web version 1.0.4.

a JPEG2000 encoding tool such as kdu_compress that supports batch encoding of images (provided to DLXS subscribers and readily available at Kakadu Software)
kdu_expand for expanding and displaying JPEG2000-compressed images (provided to DLXS subscribers and readily available at Kakadu Software)
cjpeg for use in conjunction with kdu_expand for JPEG2000 web delivery (available as part of libjpeg)

a MrSID encoding product such as MrSIDGeo that supports batch encoding of images (not free)
mrsid_retrieve for displaying MrSID-encoded images in JPEG format (free)
