Data preservation in high energy physics — •Ulrich Schwickerath — CERN, Geneva, Switzerland

We preserve our data to extend the scientific reach of our experiments. In high energy physics it is cost-efficient to warehouse data from completed experiments on the tape archives of our national and international laboratories. To use data archived in such a way we must also preserve our ability of use the data, specifically the documentation, computing environment and software of the experiments and analyses. Successful data preservation thus requires careful planning and ongoing effort. The contribution illustrates the challenges of long-term data preservation with experience from the LEP and LHC experiments at CERN. Examples will be given of the varying degrees of success in supporting new physics searches resulting from different approaches to data preservation.
