By defining a 'visibilityControllingFlagSourceColumnId' element in the timeSeriesSet, the existence of a flagSource Column for a particular timeseries (step) can be used as a condition for for example a transformation. When the configured flagSourceColumn is not existing for a particular timeseries step, the value will be perceived as 'Missing' for the transformation. All values that did not pass this validation step are removed on read. They are set to missing for equidistant timeseries and removed for non-equidistant timeseries. The flagSourceColumnId needs to be defined in flagSourceColumn.xml configuration file.
qualifierAggregation
Can have values sum, mean, min or max.
When specified all the time series that have ALL the specified qualifiers are aggregated to a single time series on read. Can not be specified when this time series set is meant for writing.
