We aim to give you an insight may always have suspected it, but this issue presents some into the programs and some of their philosophies. In this issue we will look at proof: Free Software is good for your health! BY GEORG C. F. GREVE the ways Free Software is helping in the world of medicine and health.

Unfortunately the project also plans the private and the very intimate spheres The program is easy to use thus packaging proprietary software that is of human life – as is the case for doctors preventing both errors and frustration distributable at no cost, creating a – has to fulfil certain basic criteria, which would work against the patient’s weakness for the mid- and long-term which currently only Free Software can interests.

But if enough people hope to fully satisfy. administration makes sure that express their wish to think in the long-term here, I’m sure that this decision is not carved in stone. Bringing Free Software into the medical area is something that I always considered to be quite important and if you are looking for a useful project to engage yourself in, Debian-Med will most likely be a good choice. Gnumed Among the programs used within Debian-Med is Gnumed, [8] an official GNU project designed for a paperless medical practice. The project was born in Australia, Figure 1: Gnumed prescription dialog where a heated discussion about the 88 October 2002 www.linux-magazine.com Brave GNU World COMMUNITY the Gnumed team. information about them; although it In the Gnumed team would of course also be possible to use it there are many for invoices, deliveries or accounts. physicians from The OIO-library is a metadata many different repository, which allows exchanging fields, who know metadata like plug-and-play web forms what they want, but or project descriptions between server often not how to and client. implement it.

This already shows the largest problem of this Free Software project under the GNU General Public License and GNU Free Documentation License, because lacking a full-featured Free Software Java implementation, the freedom of the project is in danger. But freedom was a major motivational factor for Christian to begin working on Res Medicinae. He wants to overcome the very expensive and proprietary scene of medical information systems and give users in less privileged countries access to a free, stable, secure, platform independent and extensive system. The project is still rather young. According to the plans, at the end of 2002, the ResMedLib framework should be consolidated and prototypes for two complete modules should be available. In 2003, the administrative module, Figure 5: JavaRisk preparing to battle printing forms and generating reports should work. a BSD license and the already mentioned lems following.

The answer is clear: We need a Free statistical module should be added.
