Description
The seminar will present a new paradigm that emerged in high energy physics around the management of big data sets collected with significant human and financial effort by complex experiments at colliders and elsewhere. These experiments are mostly unique and it would therefore be prudent to envisage some form of conservation of their respective data sets. However, HEP has little or no tradition or clear model of long-term preservation of data. It is likely that the majority of older HEP experiments are unable to analyse the original data sets, mainly because a lack of appropriate planning. An inter-experimental study group on HEP data preservation and long-term analysis (DPHEP http://www.dphep.org/) was convened in 2009 as a panel of the International Committee for Future Accelerators (ICFA). The most recent DPHEP report (May 2012) will be presented, including: the physics case, the experiment-level and laboratory-level strategy including concrete projects started at DESY and SLAC, global projects for HEP-wide sustainable data preservation and the international co-ordination proposals. The most recent reflections on these issues at LHC will be discussed as well as a rapid survey of the funding models and multi-disciplinary aspects of this new paradigm.
