Description
The event data model (EDM) of the ATLAS experiment is presented. For large
collaborations like the ATLAS experiment common interfaces and data objects are a
necessity to insure easy maintenance and coherence of the experiments software
platform over a long period of time. The ATLAS EDM improves commonality across the
detector subsystems and subgroups such as trigger, test beam reconstruction, combined
event reconstruction, and physics analysis. Furthermore the EDM allows the use of
common software between online data processing and offline reconstruction. One
important task of the EDM group is to provide know-how and the infrastructure to
secure the accessibility of data even after changes to the data model. New processes
have been put into place to manage the decoupling of the persistent (on disk)
storage and the transient (in memory), and how to handle requests from developers to
change or add to the stored data model.
