Hi, Jonathan, Two points as you search out a solution: 1. I agree with your assessment of the current RDA carrier vocabulary. You might want to look at the RDA/ONIX vocabularies (still not registered, but there are plans to do so: http://www.dlib.org/dlib/january07/dunsire/01dunsire.html). 2. These vocabularies are a start, not a finish: once RDA and the vocabularies are "published" there's an intention to begin improving them. The first step was to get the out of the text, the second to build on the NSDL Registry's vocabulary development tools (some there, some not yet) to build them up in ways that will be much more useful.
