Description
Data from high-energy physics experiments are collected with significant financial and human effort and are mostly unique.
However, until recently no coherent strategy existed for data
preservation and re-use, and many important and complex data
sets have simply been lost. While the current focus is on the
LHC at CERN, in the current period several important and unique
experimental programs at other facilities are coming to an end,
including those at HERA, b-factories and the Tevatron. To address
this issue, an inter-experimental study group on HEP data
preservation and long-term analysis (DPHEP) was convened at the
end of 2008. The group now aims to publish a full and detailed
review of the present status of data preservation in high energy
physics. This contribution summarises the results of the DPHEP
study group, describing the challenges of data preservation in
high energy physics and the group's first conclusions and
recommendations. The physics motivation for data preservation,
generic computing and preservation models, technological
expectations and governance aspects at local and international
levels are examined.
