Data for Generations - Keeping data reusable for really long periods of time

An increasing amount of published data with various data types and formats generates challenges for reusability of research data. Since published content is essential for scientific research over long time periods, reusability should not be limited by the life-time of a format. Various other limitations like unclear usage rights may also impact reuse in the scientific context.

This presentation regarding format recommendations, including surveys and an exercise, was held at the international BonaRes Data Workshop "Make the best of your data" (29. 09. 2021) by ZALF and ZB MED. The workshop's aim was introducing scientists to efficient management and proper tools that support scientists in their daily work in general and specifically when using the BonaRes Data Repository.

The presentation introduces the challenge of format diversity, which is explained in relation to digital preservation methods. Recommendations for format types when publishing data are given: open, text-based and popular formats. Further recommendations regarding files are conveyed: files without passwords, sufficient rights information and metadata. Following the recommendations supports data reusability over the long term. An exercise for the participants, ranking formats according to their suitability for digital preservation, is included. Similarly, the participants' answers to surveys regarding used data types and file formats, as well as data reuse issues are added.
