      •      Development of a WMO core profile of the ISO 191xx series of
             standards for metadata and data, encompassing the WMO Metadata
             core profile of the ISO metadata standard, including relevant ISO
             191xx feature catalogues, application schema(ta) and data product
             specification(s);
      •      Further develop procedures and guidance for the interoperability of
             metadata and data, including BUFR, CREX, GRIB, XML, NetCDF and
             HDF, and liaise with the NetCDF and the Climate and Forecast (CF)
             communities in this respect , in particular develop and maintain a
             WMO conceptual data model to facilitate the interoperability of
             metadata and data;
      •      Develop a WMO inter-programme metadata and data representation
             policy, including governance;
      •      Coordinate extensions to the WMO core profile needed to satisfy the
             requirements of all WMO Programmes;
      •      Develop guidance for the implementation and use of the data
             representation systems, metadata and the WMO core profile,
             including training aspects;
      •      Propose extensions to the ISO 191xx series of standards required for
             the WMO core profile and liaise with ISO and OGC as required.

Urgent need for sample metadata (not just GTS metadata)

                 Need for sample metadata is understood.
                 Anticipate sample metadata elements being included
                 within best-practice ‘manual’
                 Do you need complete records to ingest into WIS test-
                 systems?
                 Do you have clear scenarios or use-cases that can be
                 provided to scope the request for metadata?
                 For IPET-MDI to best support ET-WISC we will need to
                 be provided with a clear understanding of how the WIS
                 infrastructure will operate, the ET-WISC priorities & their
                 perceived barriers to implementation



                                                                     21

Urgent need for guidelines on creating and managing metadata

                 Guidelines indicating best practice methodologies for
                 construction of metadata records is a current work in
                 progress.
                 No current activity underway regarding the management
                 of metadata. Defining the process for management of
                 the standards, profiles & vocabularies falls within remit
                 of IPET-MDI – anticipated that management of metadata
                 instances is a GISC implementation concern




                                                                    22

                                                                   24
              Questions from ET-WISC
                … for discussion …

                 IPET-MDI seeks to accommodate the effort to integrate
                 ISO23950 SRU into the WIS by developing mappings
                 from ISO19115 to the SRU query string
                 IPET-MDI members have, where possible, identified
                 initiatives within their host organizations that may
                 provide ISO23950 SRU interfaces, but there is no
                 coordinated activity being promoted by IPET-MDI at this
                 time
                 The Huddle site could continue to be a forum for these
                 discussions?

Urgent need for access to searchable (ISO23950 / SRU) interfaces




                                                                  25
               Questions from ET-WISC
                 … for discussion …




                  This does not appear to be a core activity of IPET-MDI –
                  should ET-WISC look to co-ordinate experience with
                  GEONETWORK as part of the WIS implementation
                  effort?


Updates on the Member’s and secretariat’s work on
GEONETWORK and a need for sharing and coordination of this activity
                                                                     26
