The problems are large but I also wonder what part of this is in IETF scope. I asked about this in the halls after the BOF. If this work takes place in the IETF I will be very involved, but IETF expertise is primarily in protocol engineering, and I don't see much need for that here. There is a slight overlap with CDNI but not much. However, we (Internet2) need to work on these issues somewhere, and if the IETF is glad to host the work, we're glad to be active in it. -> I suggest a side discussion at the October DSII meeting in Arlington about specifics of how the IETF could help. (Alas, I can't be there, it overlaps with our member meeting.) Regardless of where the work is done, I do not think we should attempt "limiting number of PID schemes" (they, like collaboration environments or mail apps, are very subjective and attempts to quash inventiveness will be futile). Instead of putting large amounts of effort into unification and not completely succeeding, we should try for federation: define interfaces for interworking while also supporting local innovation. The "core set of metadata" is that which is to be presented to the "interoperability API" ... whether metadata is constructed that way internally should be an independent matter. Scott
