Since version 2015.02 FEWS makes it possible to configure so-called 'flagSource columns' for each individual validation step, in which the flagSource of the specific validation step will be recorded. From these flagSource columns the user can deduct which individual validation steps have been performed and to what result. Even when a defined validation step has been executed successfully and no quality flag has been changed, a default flagSource "OK" will be set for the respective flagSource column. The flagSource columns therefor provide details on all the validation steps. Since 2016.01
Configuration
FlagSource columns can be defined in FlagSourceColumns.xml regional configuration file. These flagSource Columns are stored for each timestep for all timeseries that have been validated in the FEWS database. Various configuration options allow the user to harness the Validation Status in the operational process, either by visualisation, export, conditional filtering in transformations, etc.
Within the flagSourceColumns configuration file, several columns can be defined.
flagSourceColumn
column id
Id of the column. This id is only used to reference this column from the rest of the configuration. This id is not stored in the database. This id can be changed at any time without the requirement of deleting the datastore
column name
optional element with name of the column. When not specified the id is used as the name
...
Background color of this column in the the time series dialog
timeOfValidity (since version 2016.01)
Optional element. When configured, the defined flagSourceColumn open up functionality in the time series display related to Time of Validity.
columnId
Flag source column used as base for the time of validity
defaultFlagSource
Flag source used to fill this column. Flag source should be a predefined flag source or flag source defined in the customFlagSources.xml
Example configuration
The example configuration below defines 5 validation steps. It also has the timeOfValidity element defined.
