Abstract: The EDM4hep project aims to design the common event data model for the Key4hep project and is generated via the podio toolkit. We present the first version of EDM4hep and discuss some of its use cases in the Key4hep project. Additionally, we discuss recent developments in podio, like the updates of the automatic code generation and also the addition of a second I/O backend based on SIO. We compare the available backends using benchmarks based on physics use cases, before we conclude with a discussion of curren… Show more

“…The standardization of tools is likely important in view of a future lepton collider. For Higgs factories, a common software framework, EDM4HEP is being developed [1265], that is based on a common event data model from the generator over the detector level simulation towards reconstruction and analysis. This event data model is encoded in the event format LCIO [1266].…”

“…For an introduction to the general design choices and capabilities of the podio toolkit we refer to previous publications [2][3][4]. Here, we will instead entirely focus on the most recent developments that we consider to be the most important ones; the Frame concept, Schema evolution of generated EDMs and the possibility to extend EDMs.…”

“…These include data types to represent data generated during simulation, as well as the ones encountered during reconstruction starting from raw data from the detector, up to the data types representing higher levels of reconstruction. The general structure of EDM4hep and the relation between LCIO and EDM4hep is discussed in slightly more detail in [4].…”
