Welcome to the TT-AvXML page for activities before 2017
The Task Team on Aviation XML is a team managed by WMO's Commission for Basic Systems that includes experts from the Commission for Aeronautical Meteorology and ICAO. Its purpose is to create an XML representation of meteorological information that is compatible with both WMO and aviation systems.
The Data Representation Standard
Current version of WMO IWXXM (version 1.1)The sixteenth World Meteorological Congress approved IWXXM version 1.1 (formerly known as AvXML), a WMO standard data representation to be included in the new Volume I.3 of WMO-No. 306, Manual on Codes.
The formal definition of IWXXM 1.1 is currently being edited and translated ready for publication.
The unedited version of the text is available in the following locations: changes to the Manual on Codes and guidelines on data modelling in the WMO context. Note: these links will be changed to point to the published version of the Manual on Codes when it has been prepared.
Initial documentation is provided on this wiki in draft form.
