  An inter-experimental study group, DPHEP, was formed in 2009 to
systematically investigate the technical and organisational aspects of data
preservation and long-term analysis in high-energy physics, a subject which had
hitherto lacked clarity in the field. The study group includes representation
from all major high-energy physics collider-based experiments and laboratories,
as well as computing centres and funding agencies. A major report was released
in May 2012, greatly expanding on the ideas contained in a preliminary
publication three years earlier, and providing a more solid set of
recommendations, not only concerning data preservation and its implementation
in high-energy physics, but also the future direction and organisational model
of the study group. A brief description of the DPHEP Study Group and some of
the key messages from the major report are presented.
