Release Notes
Release notes for AvXML 1.0RC2 are included in the release Package. They are available from the Release Notes wiki page.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.
