The setup of a coherent strategy for long-term analysis and preservation of HEP data is the goal of the DPHEP collaboration, a study group endorsed by the International Committee for Future Accelerators (ICFA) in charge of addressing the different issues and problematics related to preservation of HEP data and software environments.
The SFT group is actively engaged in these activities through the promotion of the CernVM- based solution for software environment preservation, which is now one of the main research lines of DPHEP. The solution basically exploits the time-machine features of CernVM-FS and the flexibility of the new uCernVM technology to recreate software environments as they were at a given time in the past.
