Workshop on Diffraction Data Deposition (DDD)

Monday August 6th 2012

Realfagbygget (Science Building), Allégaten 41, University of Bergen, Bergen, Norway

This full-day Workshop is organised by the DDD Working Group (WG), appointed by the IUCr Executive Committee to define the need for and practicalities of routine deposition of primary experimental data in X-ray diffraction and related experiments. It will take the form of a one-day workshop to review progress during the Working Group's first year of activity.

Objective: To help frame a policy to be drafted by the IUCr DDD WG on raw diffraction data deposition for final approval by the IUCr Executive Committee.

There is a public forum for discussion of the issues covered in this workshop at
