Terms of Reference for IPET-MDI

1. 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);
2. 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;
3. Develop a WMO inter-programme metadata and data representation policy, including governance;
4. Coordinate extensions to the WMO core profile needed to satisfy the requirements of all WMO Programmes;
5. Develop guidance for the implementation and use of the data representation systems, metadata and the WMO core profile, including training aspects;
6. Propose extensions to the ISO 191xx series of standards required for the WMO core profile and liaise with ISO and OGC as required.

OGC Liaison
