Free software is not the same as open source, but the two concepts are related. In the specific area of research, we always recommend making (self-) created software available and publishing it under a free licence. This simplifies the subsequent use of your software. If you are looking for a software product, we recommend that you check whether there is a suitable free software or open source product on the market. When choosing a suitable licence, there are many different licences on the market and we can therefore not recommend a licence for all use cases. Please contact us in individual cases, we will be happy to advise you on a suitable licence and also help you find a suitable place to store and publish your software. We will also be happy to advise you on legal questions regarding the use, application and publication of software in research.
