Dear Colleagues, A couple of research data matters that I imagine will be of general interest I have placed at the IUCr CommDat Forum:- The Photon and Neutron EU Facilities Open Science Cloud announced their “doi per experiment” described in this 3 minutes youtube movie clip https://forums.iucr.org/viewtopic.php?f=39&t=431 Secondly, the Swiss Universities Bulletin have produced a special issue on Research Data Management, to which I have contributed an article on Open science and the reproducibility of the scientific record https://forums.iucr.org/viewtopic.php?f=39&t=432 Best wishes, John Emeritus Professor John R Helliwell DSc Chairman of the IUCr Committee on Data
