Challenges in preservation (planning) Becker, Christoph Preservation planning software engineering scalability measurements benchmarking ground truth longevity This short paper attempts to highlight some challenges to be tackled by DP research in the next years, taking as a starting point the perspective of preservation planning. These challenges are in short: (1) Scalability (up and down) requiring (2) measurement of relevant decision factors, in turn requiring (3) benchmarking and ground truth. (4) Quality-aware emulation. (5) Move from the current closed-systems approach to open structures that accomodate evolving knowledge. (6) Move from post-obsolescence actions to 'longevity engineering'.
