Minutes

  • Choy mentioned that minutes of AIRM CCB meetings were made available for team's awareness.
  • Jan had yet to work on Issue #271
  • Dirk learnt that Amendment 81 could be delayed not only for one but two years; ongoing discussions could be the reason for not issuing an ICAO State Letter announcing the delay
  • Mark indicated that he would be making available his work on QVA for discussion before end of this year
  • The team discussed options for Mark to show his progress with the team. He would raise a GitHub issue and post whatever he want to elaborate his work
  • Choy invited team members to join the meeting with AIM/AIXM folks on Dec 9
    • Dirk and Dmitry would like to join
    • The discussion would cover (1) Data Product Specifications for MET information and (2) Issues on IWXXM referencing AIXM
      • Dmitry would like to add #216
      • Mark would like to raise the question for UoM not making reference to UCUM
  • Development of new examples has not started yet.
  • Workflow updates (Anna)
  • There was a discussion about providing test samples to showcase changed and new features during publication of release candidates and finalized version to help developers confirm their implementation. Noting that this was different from the examples included with the schemas which was intended for portraying instances for different use cases. Choy mentioned that the team may not have enough resources to provide such test suites but we could probably save the test instances used to validate schema changes during development for this purpose. He invited Mark to try this during development of IWXXM for QVA
  • Dirk mentioned that there were missing codes for certain combinations of weather phenomena like freezing rain with snow. Choy mentioned that the code list http://codes.wmo.int/306/4678 contains a list of reasonable combinations of weather elements in WMO No.306 Vol 1 code table 4678 created by a group of MET experts back in the time of IWXXM version 1. [Post meeting note: Choy found an e-mail from Greg indicating that an action should be taken by WMO Secretariat/TT-AvData to raise the issue at WG-MIE.]
  • Jan raised a couple of points:
    • The proposed delay in applicable date of relevant clauses in Annex 3 and PANS-MET to allow ample time for implementation of IWXXM should be brought up at appropriate time. He indicated that a software developer may need 6 months to develop and validate the implementation depending on the complexity of the changes and more time for deployment for their clients. Choy and other members of WG-MIE in the team would raise this in subsequent WG-MIE meetings.
    • End users were not too sure whether they need an upgrade to their system when new versions of IWXXM had been published, probably because they were not well informed of what they should be using to comply with the latest Annex 3 amendments. Choy would take a look at this.
