First tests in July 2009: XML-encoded METAR sent from Brussels

(Belgium) to Hong Kong (China) via London (UK), Singapore and Bangkok (Thailand) on 23-July-2009

ICAO AFTN is suitable for dissemination of XML-type messageso Full IA-5 character set necessaryo Only small size messages (<1800

characters) tested

Report ET-ODR 4

Future activities of CBS IPET on MDI

Assess current data-standards landscape, a.o.: ISO 191xx series OGC O&M model WXCM-WXXM (Eurocontrol + US FAA)

Develop candidate common data-model to support all MET domains First focus on aviation MET & WMO resolution 40

« essential » data In line with WMO WIS concept

Develop candidate data-encodings, including XML-type encoding

Demonstrations via test-beds Develop governance / maintenance

arrangements for data-model and -encoding
