Outcome of WIGOS Metadata Task Team (TT-WDM-1)

Note: below is just my personal analysis of publicly-available documents.

There was a meeting TT-WMD-1 in March.

* Documents: http://www.wmo.int/pages/prog/www/WIGOS-WIS/meetings/TT-WMD-1/TT-WMD-1.html

* Final Report: http://www.wmo.int/pages/prog/www/WIGOS-WIS/reports/TT-WMD-1_Final-Report_Geneva_2013.doc (pdf-converted: http://goo.gl/6jcpX)

FR§5.2 says WIGOS will develop a web portal called WIR.  Existing OSCAR will be a component of WIR in following structure:

WIR

 |

 +- SORT: standards of observing methods

 |  (I guess WIS metadata don't link to that in near future)
 |

 +- OSCAR: DB of requirements and capabilities of observatios

    |

    +- OSCAR/Surface: evolution of Volume A

    +- OSCAR/Distributed: DBs made for each regional/progamme community

FR§5.2.6 says the radar DB http://wwr.dmi.gov.tr/ is an example of OSCAR/Distributed.  I wonder where is existing satellite DB in OSCAR is located, perhaps as an instance of OSCAR/Distributed.

FR Appendix II (p.18) gives a draft spec of "Core WIGOS Metadata".  It's a list of elements with Mandatory/Conditional/Optional flags.  The elements are in conceptual level, so the encoding or instantiation has to be developed later before actual catalogue-building can be started.

Regarding the future of Volume A, FR§6.3 says it's primarily the role of CBS, but in my understanding CIMO will augment a number of elements (such as shown in Doc.7 to that meeting http://www.wmo.int/pages/prog/www/WIGOS-WIS/meetings/TT-WMD-1/Doc7_Metadata.doc ).

FR§5.2.4 shows an idea of linkage from WIGOS (WIR) to WIS.  That must raise requirement of some interface - i.e. rules of linkage (URL) to data searched by some criteria (ex station, variable, equipment etc) and sustainable operation with organizational arrangement (I mean which GISC does the service).

Similarly it is conceivable to link from WIS to WIGOS.
