This is a draft of the proposed web page for AvXML 1.0RC2. It will be moved to the correct position when the release is ready to be published.

Initial development of the WMO Logical Data Model, metce, is aimed at supporting an XML representation of weather information to support the use of XML by ICAO.

This page provides information about testing of the second release candidate of this and associated models and their XML schema.

Structure of AvXML

AvXML is built on several packages:

Packages managed by WMO

  • metce - a set of foundation building blocks to support application schema in the domains of interest to WMO, notably the weather, climate, hydrology, oceanography and space weather disciplines
  • Observable Property Model - based on work by the OGC Sensor Working Group, this allows creation of definitions that are derived from the meteorological basic types.

Packages managed by ICAO

  • iwxxm - ICAO Weather Information Exchange Model - defines the reports required by ICAO (the equivalent of METAR/SPECI, TAF and SIGMET) that are built from the components of the packages managed by WMO
  • saf - Simplified Aviation Features, that allow items such as airports, or runways to be described to the level of detail required for reporting aviation weather

More details of these packages are available on a separate wiki page.


Some examples of how the AvXML standard has been applied are available.
