It is possible to add filters for the data which was extracted of the IWXXM data into the data scheme of the WFS service. At the moment this is:
- filename in WMO naming convention scheme
- incoming date of the file
- ICAO code of the aerodrome
- ICAO name of the aerodrome
A hanbook of how to use filters with WFS could be found on the OGC Website: https://www.ogc.org/standards/filter
