The DRS is writing a version associated with the atomic dataset as defined within it. We expect modelling groups would conform to that, and update versions according to it. We could rewrite the DRS ... (and hence CMOR presumably ... but it's a bit late for that ... or maybe I'm missing something).

That means, if we leave things the way there are: there is a logical disconnect, and the risk of either vastly more data movement than is necessary, or a complex resolution problem (is my replicated "realm" level dataset the same as yours, if we've done replication at the file level).

cheers
Bryan
