If the metadata can be in an arbitrary location then it does sound like the extra GET may be unavoidable. But if the metadata can always be at a predictable location relative to the original URI, and you can figure out a simple pattern matching rule to convert the original URI to the metadata URI, then a smart agent could inspect the first URI, determine that it uses the XRI http subscheme convention, and use the pattern match to transform it into the metadata URI without doing a GET on the original URI. Would that be a viable approach for you?
