3. Christian Gerke, DESY EPICS Meeting, Legrano, 15-17 October 2008 XFEL The European X-Ray Laser Project X-Ray Free-Electron Laser 3 What do we need? –Many records –many fields –many similar records –few different fields –similar groups of records –> structure –(0...n)*(groups of) groups of records –> hierarchy
