The order in which the flagSourceColumns are configured should reflect the sequence of the respective validation steps in the validation process. This order is also used in the timeseriesDisplay - tableview, when the 'Validation Steps' are visualized. Note that the order in the configuration file is from top (first validation step) to bottom (last validation step), in the interface the order is from right (first) to left (last).

When a data value is deleted (either by the user or by a different action), the flagSources for that timestep will remain. For an individual value in the time series table, the history of that value can be shown using the right-mouse menu - Show history (CTRL+H). This menu also shows the 'state' of the flagSourceColumns for each time the value was changed in the datastore.

A Tv button becomes available in the time series button panel, which activates all 'Time of Validity' related functionality. The button is only be visible in the button panel, when the timeOfValidity element has been defined in the flagSourceColumns.xml file. Note that none of the Tv functionality is available when the Tv button is not activated.
Image of Tv button in Toolbar
Besides the functionality as described below, when the Tv button from the toolbar is activated, the time series display will be set to 'edit mode' automatically.

An example for a single timeseries is given in the image below
The Tv (Time of Validity) for a display node needs to be calculated by aggregating the Tv's for all the timeseries displayed under that node. Display nodes are configured in the displayGroups.xml configuration file.
...
When the timeOfValidity element has been defined in the flagSourceColumns.xml file, the Time of Validity will be calculated for each timeseries in the database lister. Note that - different from the time series in the time series display - the Tv is calculated based on the complete time series.

- using an option through the rightmouse menu
- using a simple keyboard shortcut: CTRL+SHIFT+T
The update will only take place for the view period of the display. When this update function is used when Tv is outside the view period of the display, a pop up will be displayed warning the user that a validation gap would be created. The update action will not be performed in this case. This might for example happen when the validator updates the flagSourceColumns using the functionality described above - without saving. Delft FEWS does not know in that case that the Tv should be updated, as the Time of Validity is only recalculated after the timeSeries have been saved.
Export of flagSourceColumns
In the FEWS client, it is possible to use the validation status as a condition for the interactive export. A specific flagSource Column can be selected which is used as a filter for the export. The flagSource Columns are included for the PI-XML data type and will always be exported when available. The GeneralCSV datatype can be configured as an interactive export type as well. The flagSource columns that should be exported can be configured in the explorer.xml configuration file.
In the regular timeseries exports, the export of flagSourceColumns is supported for the PI-XML format and the GeneralCSV format. In PI-XML, the flagSource columns will always be exported. When exporting using the generalCsv export format, inclusion of flagSourceColumns can be defined in the configuration with the use of Table Layout.
