replication – Choosing name for MongoDB replica set

Are there any guidelines for choosing names for MongoDB replica sets? The documentation seems to mostly contain examples like rs1, rs-test, … Is replica set name fully redundant, or could it reflect some entity?

I am setting up a new MongoDB service in my organization. Eventually we plan to serve multiple applications, so I think the replica set names that appear in the customer’s connection string should be generic, but meaningful. Would love to hear the words of wisdom from the experienced DBAs.
