Well, one way to look at the IETF is as a set of structures the enable whoever is interested in a specific technical topic to come together under known rules; so if the big data community does the work here, that community is part of the IETF and thus does have the related expertise. One of advantages of participation as the key identifier, rather than membership, is that we have that fluidity. But beyond that, there is a lot of IETF-relevant protocol work to be done in this space: in network discovery, online access methods,and in access control. We didn't focus on that part of the work in the BoF because it generally needs to come after the core identifier interoperability work has gotten a mental framework built. In many ways, though, that's when real cross-fertilization with existing IETF work will get going. While you could argue that that is after that core interoperability story is ready that it should come to the IETF, I think we all benefit if it gets early exposure. To take one example, a simple way to create interoperability in a system like this is to have a layer of indirection which creates a new identifier in a distributed global namespace by hashing the existing identifier with other metadata so as to create a new globally unique name within the new namespace. You go to the new namespace manager to retrieve the mapping and there you go, right? Of course the access control methods on such a scheme are three kinds of nightmare and the new namespace manager needs a global caching scheme to prevent the index from being unwieldy, but that creates a discovery/redirection scheme that looked so easy to avoid with a single, global, trusted namespace manager. If you know what a particular interoperability method will end implying in terms of related network infrastructure, access methods, and access control, you avoid that simplistic method of creating interoperability via single indirection (or at least you know what you're getting into). Giving the Big Data folks a home here helps makes sure that those issues get surfaced early, and that may be a benefit to all of us. Just my two cents, Ted Hardie
