IFC (IFC4X3_ADD2) under development IfcRegularTimeSeries Semantic definition

In a regular time series, the data arrives predictably at predefined intervals. In a regular time series there is no need to store multiple time stamps and the algorithms for analyzing the time series are therefore significantly simpler. Using the start time provided in the supertype, the time step is used to identify the frequency of the occurrences of the list of values. Entity inheritance Attributes

# Attribute Type Description
IfcTimeSeries (9)
1 Name IfcLabel

An unique name for the time series.

2 Description OPTIONAL IfcText

A text description of the data that the series represents.

3 StartTime IfcDateTime

The start time of a time series.

4 EndTime IfcDateTime

The end time of a time series.

5 TimeSeriesDataType IfcTimeSeriesDataTypeEnum

The time series data type.

6 DataOrigin IfcDataOriginEnum

The origin of a time series data.

7 UserDefinedDataOrigin OPTIONAL IfcLabel

Value of the data origin if DataOrigin attribute is USERDEFINED.

8 Unit OPTIONAL IfcUnit

The unit to be assigned to all values within the time series. Note that mixing units is not allowed. If the value is not given, the global unit for the type of IfcValue, as defined at IfcProject.UnitsInContext is used.

HasExternalReference SET [1:?] OF IfcExternalReferenceRelationship FOR RelatedResourceObjects

Reference to an external reference, e.g. library, classification, or document information, that is associated to the IfcTimeSeries.
