WIS2 to GTS question

[golfvert]

At the moment, in the Technical Requirement for Data Provider wanting to use the gateway, it says:

. The GTS header CCCC code to be used for the bulletins published on their behalf.
. The list of GTS bulletins, and, where appropriate, their cut-off times, to be published by the Gateway on their behalf.

I don't really understand and I don't agree with the part I get...

Typically, the CCCC will be available in each notif message from the producer. So, there is no predefined list...

Then below in the same adoc:

. Add the CCCC code designated by the Member to the Gateway's publication whitelist.
. Complete configuration required in the MSS for each bulletin specified by the Member; e.g., set up the data import channel, set the cut-off time, etc.

@6a6d74 Can you explain (it seems you wrote that) ?

I also want to add a question. The doc says "Subscribe to notifications on the topic: cache/a/wis2/{centre-id}/data/core/#". So we are not forwarding recommended data from WIS2 to GTS?
