Description
TimeSeries for an Observation is defined by the associated DataItem’s property representation as TIME_SERIES.
DataItem with TIME_SERIES representation MUST have a category of SAMPLE.
Figure TemperatureTimeSeries shows the model for Temperature (Sample type) with a Representation type of TimeSeries.
Note: See Figure AbsTimeSeries Schema for XML schema.
TimeSeries MUST report multiple values at fixed intervals in a single Observation. At minimum, one of DataItem or Observation MUST specify the sampleRate in Hertz(values/second); fractional rates are permitted. When the Observation and the DataItem specify the sampleRate, the Observation sampleRate supersedes the DataItem.
The Observation MUST set the timestamp to the time the last value was observed. The 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 Representation type.
