add guidance on centre-id #51

Closed tomkralidis closed 11 months ago

tomkralidis commented 1 year ago

WTH should provide guidance (requirements or recommendations) on how centres should craft their centre-id value. Examples:

golfvert commented 1 year ago

The centre-id name should be based on the name of the institution, whether it is an acronym (eg. smhi, cma,...) or a "full name" (eg. meteo-france, maroc-meteo,...).

from @solson-nws: Consider adding language for centre-id that makes it clear the distinction between organization vs. originator/provider level. Perhaps one of the examples could be something like noaa-nws-spc

golfvert commented 1 year ago

I don't understand the point above. For me, for NWS the "base" of potential multiple centre-id should be: us-noaa-nws

Depending on local choices, one organization may decide to run multiple WIS2 Nodes (eg. one for the NC function, one every DCPC function,...). In this case, we would have the "base" eg. fr-meteofrance and then specialized WIS2 Nodes:

And following the same logic, the Global Broker operated by Météo-France could be:

At the moment, the Global Broker is not producing messages for itself. However, this might change to eg. use MQTT messages for monitoring/management purposes.

So, WIS2 Node, Global Caches, Global Brokers, Global Discovery Catalogs,... everything would have it own centre-id.

Agree with @golfvert ... the centre-id should provide some form of descriptive token, ideally based on the WMO function that the centre is fulfilling. For many, that will simply be nc.

For example: uk-metoffice-nc

Need to add this guidance to the Guide.

Decision The Secretariat will make sure that the rules for centre-id are applied when a centre is submitting a WIS2 node registration

The rules are in the specs centre identification

Examples and the specs will be provided in the guide.
