Description

A new event data format has been designed and prototyped by the CMS collaboration to satisfy the needs of a large fraction of Physics Analyses (at least 50%) with a per event size of order 1 Kb. This new format is more than a factor 20x smaller than the MINIAOD format and contains only top level information typically used in the last steps of the analysis. The talk will review the current analysis strategy from the point of view of event format in CMS (both skims and format such as RECO, AOD, MINIAOD, NANOAOD) and will describe the design guidelines for the new NANO format.
