AvXML-1.0RC1

AvXML - testing of version 1.0 Release Candidate 1




Consultation on AvXML v1.0 RC1 is now closed.

Testing of AvXML

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 first release candidate of this and associated models and their XML schema.

Version 1.0RC1 of AvXML.

TT-AvXML ran a consultation period for comments on issues with implementing IWXXM and METCE to create XML representing operational meteorological reports for aviation. This ran for December 2012 and January 2013. Version 1.0 is intended to provide an XML representation that is exchanged in the OPMET TAF, METAR, SPECI or SIGMET formats.

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
  • Meteorological Basic Types - classes extending the concepts of the GML "Measure" class to represent physical quantities in the domains of interest to WMO
  • 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
