Program

• 9.00 - 10.30, Keynote by Peter Buneman, University of Edinburgh
  Abstract: Nearly all the data we rely on -master data, curated data, reference data- is now held in some kind of database, be it a traditional database or some form of ontology. Databases, unlike traditional publications and records, change over time in both content and structure. This leads to some interesting questions for the preservation of this important data. Why is preservation important? If so how much of the history of data should we preserve: should we record every state or every transaction of the database? Also how and in what form should we preserve it: can we rely on the survival of database management systems and other software for this purpose?
  These questions lead to some interesting challenges not only for computer scientists but also for the economics and practice of data publication. For example, the traditional distinctions between those who create (or author) data, those who publish data, and those who archive data are fast disappearing.

  Abstract: Data from high-energy physics experiments are collected with significant financial and human effort and are mostly unique. At the same time, there is no coherent strategy for data preservation and re-use, and many important and complex data sets are simply lost. While the current focus is on the LHC at CERN, in a period of a few years, several important and unique experimental programs at other facilities will come 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.
  This talk describes the problems of data preservation in high energy physics and the first conclusions and recommendations of the study group. The physics motivation for data preservation, generic computing and preservation models, technological expectations and governance aspects at local and international levels are examined. The group now aims to publish a full and detailed review of data preservation in high energy physics in 2011.
