The Open eXchange Data Format, or OpenXDF, is an open, XML-based standard for the digital storage of time-series physiological signals and metadata. OpenXDF primarily focuses on electroencephalography and polysomnography.
History
Neurotronics began work on OpenXDF in 2003 with the goal of providing a modern, open, and extensible file format with which clinicians and researchers can share physiological data and metadata, such as signal data, signal montages, patient demographics, and event logs.
Neurotronics released the first draft of the OpenXDF Specification just before the 18th meeting of the Associated Professional Sleep Societies in 2004. Neurotronics has since relinquished control of the format to the OpenXDF Consortium.
Compatibility
As of version 1.0, OpenXDF is 100% backward compatible with the European Data Format, the current defacto standard format for physiological data exchange.
