Leibniz MMS Days 2017 - Abstract
Software is widely used and referenced in research and scientific publications. Hence, just like the results published in an article, associated software should be preserved and made long-term accessibly as well. Due to the nature of software and its dynamic aspects, this is rather challenging though. Very commonly, only related materials, such as a software's documentation, parts of its source code or change logs, are freely available. However, these can be very valuable to comprehend or reproduce experiments described in literature. We found that a big portion of this data is provided on the Web. Around 60% of the software webpages we analyzed link to documentation, while another 50% even contain some artifacts of the actual software [1, 2]. Web Archives are a way to preserve this information and allow for long-term accessibility, even if the software and corresponding information change. Although many of those websites are already archived, our study shows that the evolution of a software is not always well captured. Therefore, we are working towards a pro-active approach to archive software on the Web in the future as part of the scientific process.
