Minor nit in the problem definition: "...simple set of mechanisms (the PROPFIND and GET methods) to locate resources of interest, those meeting client-defined criteria." I think this would be clearer if everything after the comma was deleted. also in problem definition: "capabilities of the modern storage systems." I'm not sure what the queen's English would have to say about this sentence but I suspect the "the" should be removed. Other than these two nits I love the new charter! Very well written. Congratulations are due to all.
