scope:

This Recommendation describes the data model for the sleep management service. Sleep data can be expressed through data measured by various sensors such as electrocardiogram (ECG), electroencephalogram (EEG) and acceleration sensors. These data are complicated and difficult to express in an integrated system. This Recommendation describes a structured model of data for expressing data collected from sensors as information such as sleep time, sleep stage and sleep goal, to be applied to sleep management services.
