Description
TimeSeries for an Observation is defined by the associated DataItem::representation as TIME_SERIES.
DataItem::representation as TIME_SERIES MUST have DataItem::category of SAMPLE.
Figure TemperatureTimeSeries shows the model for Temperature («abstract» Sample type) with a «abstract» Representation type of TimeSeries.
Note: See Section Representation Schema Diagrams for XML schema.
TimeSeries MUST report multiple values at fixed intervals in a single Observation. At minimum, one of DataItem::sampleRate or «abstract» Sample::sampleRate MUST be specified. When both are specified, the «abstract» Sample::sampleRate supersedes the DataItem::sampleRate.
Observation::timestamp MUST be set to the time the last value was observed. The «abstract» Sample::duration MAY indicate the time interval from the first to the last value in the series.
Section Value Properties of TimeSeries defines additional attributes for an Observation with TimeSeries «abstract» Representation type.
