    "abstract": "The ATLAS High Level Trigger (HLT) consists of two selection steps: the\nsecond level trigger and the event filter. Both will be implemented in\nsoftware, running on mostly commodity hardware. Both levels have a coherent\napproach to event selection, so a common core software framework has been\ndesigned to maximize this coherency, while allowing sufficient flexibility to\nmeet the different interfaces and requirements of the two different levels. The\napproach is extended further to allow the software to run in an off-line\nsimulation and reconstruction environment for the purposes of development. This\npaper describes the architecture and high level design of the software.",
