Eliot, Your question takes us to other questions to which I don't know the answer... but they do have implications for the community. I note that I would know the answers if I were privy to international IAB discussions, RSOC discussions, and discussions within the RFC Editor function but, by and large I'm not (and you may know more about some of this than I do). For example: There were discussions for a while about the RFC Editor taking on publications for some other bodies. When I was last involved, it wasn't clear whether, if that happened, it would be as a fifth stream or a separately-named and identified document series. I also don't know whether idea is now completely deal or might come back up some day soon. I also don't know what the contract with Crossref says or how they feel about assigning multiple identifiers to the same publisher (or, if they will allow it, what they charge for the second one). For the reasons that Melinda discussed (abbreviated above), I think that having a different publication series use the same DOIs as the IETF/IAB/IRTF/ISE RFC Series would be a decision that community should be consulted on, with the option of using a little apparent hierarchy as a better way to resolve the problem than debates about opacity. FWIW, my experience suggests that while I would agree that "Additional hierarchy comes with its own complexities.", providing for the possibility of cleanly adding additional hierarchy often does not. "1.1149" is no more complex than "rfc1149". It might involve more complexity (or make it easier to have different staff maintain databases) when one adds "2.54321" in association with a different document series or subset. And, course, for someone looking up a DOI through DOI lookup mechanisms, they are all opaque strings and nothing makes any difference. john
