INTRODUCTION
The DICOM "Basic Worklist Management - Modality Worklist Management SOP Class" allows
modalities to query and retrieve worklist information from hospital information systems offering a
DICOM Modality Worklist SCP interface.
The OFFIS wlmscpfs utility supports the Modality Worklist Management SOP Class as an SCP,
allowing clients to connect and to query worklist information. However, wlmscpfs is not a hospital
information system. Therefore, worklist entries must be created, updated and deleted manually.
Since the DICOM services do not support this, a WWW server application has been developed which
allows to use a web browser from any workstation in the demonstration network to create, edit and
delete worklist entries. During DICOM exhibitions, this WWW server will reside on a test workstation,
so that vendors participating in the demonstration only require a web browser on their systems.
PREREQUISITES
1. Web Browser
The Web Server component utilizes the HTML3 <TABLE> tags. Therefore, the web browser used
should support either HTML3 or HTML2 with Netscape extensions. We recommend Netscape 2.01
(any platform).
2. Web Server
The CGI scripts have been developed for the NCSA HTTPd 1.5 web server. However, any web
server supporting the same CGI interface should work. NCSA HTTPd 1.5 is available on many ftp
sites, including:
ftp://ftp.uni-oldenburg.de/pub/unix/net/www/server/ncsa-httpd.
3. Perl Interpreter
The CGI scripts are written in "perl", an interpreted script language. The scripts have been
developed for GNU Perl 4 (Patchlevel 36) and have also been successfully (though, shortly)
tested with GNU Perl 5 (Patchlevel 1). GNU Perl 4 is avaible on many ftp sites, including:
ftp://ftp.uni-oldenburg.de/pub/gnu/perl
We recommend to install the perl binary as /usr/local/bin/perl.
