Filtering Capabilities WFS

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/ .
