Description
Going back in time by about 30 years or more, the CERNLIB library was used by a large number of experiments and collaborations, across a huge number of platforms and architectures. Written (mostly) in C and Fortran, it contained a large number of highly optimized tools, among them the "Physics Analysis Workstation (PAW)", a popular tool to visualize scientific data at the time, and the predecessor of Root. While no longer officially supported for more than 20 years, CERNLIB is still alive and plays an important role in data preservation. This presentation tells the story about how xrootd came into the game of data preservation, and how it can be used in this context, within the original frameworks of old experiments.
