DESY has a long history in High Energy Physics (HEP) and Synchrotron radiation. DESY operates a Tier-1 centre for the LHC project and has proven expertise in the management and storage of very large data volumes. DESY jointly provides the major software framework (dCache) for large scale and secure data storage and is currently establishing the infrastructure for long term archival and management of the data and metadata from all photon science experiments on site, enabling remote access to data as well as dedicated compute resources, the PaNdata data policy framework being a crucial element for this effort. DESY is currently operating two dedicated synchrotron sources (Doris and Petra III) as well as a free electron laser for the VUV and soft X-ray wavelength regime. (FLASH). Although Petra III, the most brilliant synchrotron source world wide, became operational only very recently, an extension of Petra III to host additional instruments is already in planning phase. The construction of the European XFEL (, is progressing well and construction of a second FLASH facility will start soon, accompanied by the foundation of a Center for Free Electron Lasers (CFEL) as well as a Center for Structural and System Biology (CSSB). In parallel, detector development is rapidly progressing, which will allow to obtain diffraction images at a sub-millisecond timescale to cope with the unique time structure of the European XFEL laser light. DESY, in close co-operation with the Max-Planck Society (MPG), the European Molecular Biology Laboratory (EMBL) and the Helmholtz Centre Geesthacht, which operate several instruments at DESY lightsources, supports several thousand users per year performing photon science experiments, ranging from material sciences to tomography of biological samples. To fully exploit the scientific opportunities at the different light as well as neutron sources, the standardization of experiment descriptions, data formats and policies across facilities is a crucial element. Based on this, implementation of new technologies fully exploiting the capacities of parallel software and dedicated multi-core architectures will become feasible, thereby creating a scalable infrastructure for new analysis and data flow frameworks.
