Abstract

“Our data are going to be valuable for science for the next 50 years, so please make sure you preserve them and keep them accessible for active research for at least that period.”
 These were approximately the words used by the principal investigator of the Kepler Asteroseismic Science Consortium (KASC) when he presented our task to us. The data in question consists of data products produced by KASC researchers and working groups as part of their research, as well as underlying data imported from the NASA archives.
 The overall requirements for 50 years of preservation while, at the same time, enabling reuse of the data for active research presented a number of specific challenges, closely intertwining data handling and data infrastructure with scientific issues. This paper reports our work to deliver the best possible solution, performed in close cooperation between the research team and library personnel.

Highlights

  • The Kepler Asteroseismic Investigation is part of the scientific organisation of the NASA Kepler mission1 to observe stars for the possible discovery of extrasolar planets (Kjeldsen et al, 2010)

  • KASOC consists of a website where data and documentation from NASA can be retrieved alongside with the derived data products, documentation, journal articles and related materials produced by the Kepler Asteroseismic Science Consortium (KASC) members

  • The extended mission has been named K2, and the KASC and KASOC remain active in the processing and scientific exploration of new data

Abstract “Our data are going to be valuable for science for the 50 years, so please make sure you preserve them and keep them accessible for active research for at least that period.”. These were approximately the words used by the principal investigator of the Kepler Asteroseismic Science Consortium (KASC) when he presented our task to us. The overall requirements for 50 years of preservation while, at the same time, enabling reuse of the data for active research presented a number of specific challenges, closely intertwining data handling and data infrastructure with scientific issues. An earlier version of this paper was presented at the 12th International Digital Curation Conference.
