Agenda (Draft)

1. Potential implication of further reviews required by ANC on the comments to the METP endorsed proposals to ICAO Annex 3

   • It is understood that the process to approve IMP endorsed proposals to ICAO Annex 3 will continue. They will be published as Amendment 81 and become applicable in Nov 2024. For METP endorsed proposals the approval process will be delayed and hopefully be published as Amendment 82 and become applicable in Nov 2025.
   • Recalling that the development of IWXXM release candidate has leapfrogged the approval of the METP endorsed proposals, the risk for the approved version being different from the proposed one has inevitably increased. ICAO Secretariat subsequently advised that "During the consultation phase, there were no comments from States and International Organizations on solely IWXXM-related proposals, while there are several comments on the proposed Standard for VONA exchange via IWXXM, suggesting it should be kept as a recommended practice."
   • Noting also that there are voices from some members of ICAO WG-MOG wishing to start trial production of QVACI by Nov 2024 even though Amendment 82 has yet to be approved, it is proposed to pursue with the public consultation in late Jan/early Feb 2024. Those who would like to conduct tests can make use of the release candidate published on http://schemas.wmo.int/iwxxm by then.
   • We will need to rename the version from 2024-xRC1 to 2025-xRC1 before publishing the release candidate for public consultation.

2. Setting up of sub-groups to:

   • Review existing codelists used by IWXXM, advised possibility of consolidation, proposed consolidated lists and implementation plan
   • Review the replacement of text mentioning WMO No.49-2 by ICAO Annex 3/PANS-MET in IWXXM models, schemas, documentations (e.g. WMO No.306 Vol. I.3), websites, etc., proposed respective changes and implementation plan

3. Some other potential activities requiring establishment of other sub-groups:

   • Development of shared representations to be used by iwxxm:originatingCentre (if necessary), iwxxm:phenomenonGeometry (if necessary) and iwxxm:phenomenonProperty. This ties in with the development of IWXXM-SX to support future MET information services on SWIM
   • Exploration of the workflow to develop JSON version of IWXXM and recommend if this should be made available in parallel with XML schemas
