add KPIs on WCMP2

[tomkralidis]

WIS2 encoding specifications have 1. conformance classes and 2. key performance indicators (KPIs). KPIs provide valuable feedback in support of continuous improvement of metadata.

Current WIS2 KPI implementation can be summarized per below:

Specification	KPI	Status
WCMP2	https://wmo-im.github.io/wcmp2/kpi/wcmp2-kpi-DRAFT.html	Draft
WNM	https://wmo-im.github.io/wis2-notification-message/kpi/wis2-notification-message-kpi-DRAFT.html	Draft
WME	None

Steps in KPI implementation:

• determine document target (manual, guide, cookbook) (TT-W2IT)
• review/update KPI implementations (TT-WISMD)
  • WCMP2
  • WNM
  • WME
• approval/consensus
  • TT-WISMD
  • ET-W2IT
• update of target document(s) (@tomkralidis)

Personally, I think that KPI makes really sense for WCMP2. Not for the others. WNM is strict in the spec, only metadata_id really makes a difference in terms of KPI.
Same for WME, we follow cloud event spec. Done.

TT-WISMD 2025-10-06

• WCMP1 KPIs were a specific chapter in the WIS1 Guide (not the Manual)
• We can integrate into the WIS2 Guide
  • add annex/appendix on "Key performance indicators" and reference from the relevant parts of the document accordingly
    • WCMP2
      • use only section 2
    • WNM
      • only 1 KPI (properties.metadata_id given it will become a requirement)
      • ACTION: @tomkralidis remove KPI support altogether in WNM
    • WME
      • defer and consider KPI implementation as required once WME is formally approved/published
• final approval levels
  • Guide: INFCOM
  • Manual: Executive Council or Congress (whichever happens first in time)
• timelines
  • 2025-12-31: TT-WISMD review/approval
  • 2025-06-30: ET-W2IT review/approval
  • INFCOM-4: Q3/Q4 2026

ACTION: TT-WISMD to review the existing WCMP2 KPIs before June 2026 (target=INFCOM-4) by end 2025.

TT-WISMD 2025-10-07:

• KPIs removed from WNM via remove KPI definition wis2-notification-message#171

Add section(s) on KPIs for WCMP2 (only section 2) and WNM (only for properties.metadata_id) to the WIS2 Guide.

Adding a new section to the Guide is a reasonably large change - suggesting this should be scheduled for INFCOM4. Also note that there will be broader discussion on KPIs at INFCOM4 relating to the performance of Global Services. Consequently, it could make sense to bundle all the KPI items in the INFCOM4 release?

@tomkralidis - this is currently scheduled for FT2026-1. Keep in that release or push to INFCOM4?

ET-W2IT meeting 5-Jan-2026

@tomkralidis commented that TT-WISMD are meeting on 6-Jan to review / amend KPIs for WCMP2. Their discussion will include deciding how / where to include the KPIs in the TechRegs. ET-W2IT asked to review KPIs once all the proposals from TT-WISMD have been merged. Scheduled for next meeting on 19-Jan-2026.

ET-W2IT meeting 19-Jan-2026

@tomkralidis reported that TT-WISMD had proposed some changes to the KPIs. Most of these have been implemented, one is outstanding. @tomkralidis will report back to ET-W2IT in 2-weeks (ET-W2IT meeting on 2-Feb-2026).

Update: WCMP2 KPIs are now reviewed by TT-WISMD in full, and available at https://wmo-im.github.io/wcmp2/kpi/wcmp2-kpi-DRAFT.html for further review and comment.
