We helped organize a Dagstuhl seminar on Global Measurements: Practice and Experience from January 04–07, 2016. This was a followup of the seminar on Global Measurement Framework. The second seminar aimed at discussing the practical experience gained with building global measurement platforms. It brought together people who are actively involved in the design and maintenance of global measurement systems, who do research on the data delivered by global measurement systems, and who use data derived from global measurement systems in order to manage networks or services or as input for regulatory decisions. For details, see the seminar report.
