REGISTRATION.DISCOVERY
Advisory
Subject Name Syntax
_RV.INFO.RVCM.REGISTRATION.DISCOVERY.subject
Purpose
A listener presents this advisory when it discovers a new (previously unfamiliar) sending CM transport.
Remarks
Discovery occurs when a listening CM transport receives a labeled message from a CM sender that is not listed in the listener’s ledger. Four things happen as a result (not necessarily in this order):
• | Rendezvous software queues the inbound message (but this message is not itself certified). |
• | Certified delivery software adds the sender’s name to the listener’s ledger, as a source of messages on the subject. |
• | The listener automatically requests certified delivery of the subject from the sender. |
• | The listener presents this advisory message. |
The subject
element is the subject name of the certified message. The subject often consists of several elements, so the wildcard character ">"
(rather than "*"
) is the correct way to match all subjects in this position.
