Nevertheless experimental facilities such as synchrotrons and free electron lasers may have additional requirements, mostly related to the necessity of managing the access for thousands of scientists. A complete data lifecycle describes the seamless path that joins distinct IT tasks such as experiment proposal management, user accounts, data acquisition and analysis, archiving, cataloguing and remote access. This paper presents the data lifecycle of the synchrotron ELETTRA and the free electron laser FERMI. With the focus on data access, the Virtual Unified Office (VUO) is presented. It is a core element in scientific proposal management, user information DB, scientific data oversight and remote access. Eventually are discussed recent developments of the beamline software, that holds the key role to data and metadata acquisition but also requires integration with the rest of the system components in order to provide data cataloging, data archiving and remote access. The scope of this paper is to disseminate the current status of a complete data lifecycle, discuss key issues and hint on the future directions.
