  • Review and discuss the draft document version 0.1

    • Lifecycle section

    • Discussion if time permits:

      • What are the distinctions between Information life cycle and information management life cycle?

      • Which one should we be focusing on in this document?

Discussion topics









  • David from the WMO Secretariat will be supporting the ET.

  • Hassan, as WIS 2.0 manager in Secretariat, will continue supporting the team for a while.

  • Reschedule of INFCOM 2nd Session: from February 2022 to November 2022.

  • a draft to be proposed to INFCOM, and then be delievered to Cg-19 (2023). work process is INFCOM--EC74-Cg2023

    • Question: do we collect comments for the drafted version within experts.

    • (Ge Peng) Draft to be ready at the beginning of October 2022)

    • (Enrico) No precise date. October 2022 is safe.

    • The team agrees to be working on document to keep momentum going.




  • recognition process: stations not include stations with over 100 years' records but also other shorter records stations.

  • 1991-2020, by 2022, test is going on. Collection of these normals will commence in October 2021 and be concluded by late 2022, ahead of Cg-2023.

  • daily climate message: summary of important climate parameters, daily climate guidance. In finalising Guidance, the DayCli team is considering measurement type issues; data should be quality controlled.

  • openCDMS, direct link with our ET. WIGOS MDR standards will be the basis of the openCDMS data model. Recommendation: project team decided to go to Amazon cloud for OpenCDMS prototyping.


Ge Peng

  • expert team members on climate hydrology are invited to review draft



WIS 2.0 Workshop

  • There are 11 presentations in the WIS2.0 workshop, including 4 categories: data exchange, data discovery, Earth system domains and LDCs and SIDs.

  • Lessons learned: WIS2.0 is not a dream; Web services and APIs for data exchange and data discovery.

  • (Enrico) There will be a new demonstration projects. TT WIS Metadata team will work with Wikimedia team to publish the data, with the function of harvesting OSCAR data into Wikimedia.



  • Question 1: What are the distinctions between Information life cycle and information management life cycle?

    • (Ge Peng) Information life cycle is more about: from curation to preserve to publish to be used; information management life cycle is about life cycle stages of managing information, focusing on different activities.

    • (Hassan) Information management is how to manage the information.

    • (Axel) Backgound information is suggested to be added.

  • Question 2: Which one should we be focusing on in this document?



Lifecycle section

  • There are two parts, from William and Rachid, which William has attempted to merge.

  • This makes three documents: 1 from William; 1 from Rachid; 1 combined version.

  • The team considered that there was little benefit in attempting to separate out the information lifecycle and information management lifecycle concepts. In any case, Enrico noted that it would be hard to explain to users what the difference was, and therefore probably not helpful in achieving the overall aim of providing clear guidance.

  • Ge Peng) agrees that there should be no distinction.

  • (Hassan) Information management is a wide subject. to focus on generic terms to provide for all WMO programs. Draft version to be ready is the first step. The 2nd step is to collect comments from experts within interested experts.

  • (William) Document structure is OK. The lifecycle chapter should serve as an introductory chapter to rest of the document.

  • (Axel) Information lifecycle is part of Information management lifecycle. any guidance for implementation of information management lifecycle?

  • (Enrico) lifecycle is the guidance from the producers' point of view. Different communities may have different needs. generic guidance + external document to be linked for reference.

  • (Ge Peng) agrees that the ET-IM Guidance document should be simple, clear, high-level and be developed further by various communities on their own.

  • (Peng Wang) Information management lifecycle is more of mechanism to provide new information.

  • (Enrico) all the elements are included in the current document structure. We should stick to the structure.

Action items

William to share the 3rd (merged) version of the lifecycle Chapter with Rachid for his comments, and once this is finalised, the Chapter placed on the Confluence page for team members' comments.
the Secretariat to compile the various draft Chapters into one document, so Team Members can better assess the flow and consistency of the document.
