High Energy Physics experiments initiate with this Study Group a common reflection on
data persistency and long term analysis in order to get a common vision on these issues and
create a multi-experiment dynamics for further reference.
The objectives of the Study Group are:
Review and document the physics objectives of the data persistency in HEP.
Exchange information concerning the analysis model: abstraction, software,
documentation etc. and identify coherence points.
Address the harware and software persistency status.
Review possible fundings programs and other related international initiatives.
Converge to a common set of specifications in a document that will constitute the basis
for future collaborations.
A series of workshops have been held by the Study Group, access to which can be found using
the links below.
The 3rd workshop was preceded by a public
The first DPHEP publication, containing the
initial recommendations of the Study Group was released in December 2009.
This was followed by a more comprehesive, second
publication in May 2012.
