    "abstract": "Among the many challenges presented by the future ATLAS detector at the LHC\nare the high data taking rate and volume and the derivation of a rapid trigger\ndecision with limited resources. To address this challenge within the ATLAS\nsecond level trigger system, a Region-of-Interest mechanism has been adopted\nwhich dramatically reduces the relevant fiducial volume necessary to be readout\nand processed to small regions guided by the hardware-based first level\ntrigger. Software has been developed to allow fast translation between\narbitrary geometric regions and identifiers of small collections of the event\ndata. This facilitates on-demand data retrieval and collection building. The\nsystem is optimized to minimize the amount of data transferred and unnecessary\nbuilding of complex objects. Details of the design and implementation are\npresented along with preliminary performance results.",
