A comment about the time series.

Key

KeywordValueStruct

A keyword value pair which characterizes the underlying nature of this value. The key value may provide part of the unique identity of an instance of a concept or it may characterize the underlying concept. The key value will be defined within the specified keyword naming system. This is essentially a classification of the data in the specified system (keyword).

Maximum

DimensionlessMeasure

The maximum value within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

Mean

DimensionlessMeasure

The arithmetic mean (sum divided by count) of all values within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

MeasureClass

MeasureClass

Defines the type of measure that the time series represents. If this is specified then unit must be specified. This may be redundant to some information in the keys but it is important for allowing an application to understand the nature of a measure value even if it does not understand all of the underlying nature.

Median

DimensionlessMeasure

The median value of all values within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

Minimum

DimensionlessMeasure

The minimum value within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

StandardDeviation

DimensionlessMeasure

The standard deviation of all values within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

Sum

DimensionlessMeasure

The sum of all values within the time range of dTimMin to dTimMax. Element "unit" defines the unit of measure of this value.

Unit

UomEnum

If the time series is a measure then this specifies the unit of measure. The unit acronym must be chosen from the list that is valid for the measure class. If this is specified then the measure class must be specified.
