Cern announces open-data policy

Data from Large Hadron Collider experiments to be released publicly after five years

The European Organization for Nuclear Research, Cern, has announced that it will openly release data produced by experiments using its Large Hadron Collider particle accelerator, a move it said was intended to make science more accessible.

“The policy provides a progressive framework for the openness and preservation of experimental data,” said Jamie Boyd, who convened the working group that created the policy, which was endorsed on 11 December by the major LHC collaborations Alice, Atlas, CMS and LHCb.
