I don't have a lot of hands-dirty experience with data here, but my feeling is this is a reasonable approach. Thinking purely practically as a programmer, I suspect that, as you start to explore more and more tree display cases, you'd find it's quite difficult to come up with a completely general set of SKOS extensions/add-ons that would allow you to layer the required display information as more RDF statements on top of the existing SKOS RDF data - although I think it would be worth enumerating some test cases and evaluating some RDF representations because this is just a hunch. Some sort of companion representation for the tree display data as XML or JSON sounds like a good idea, for now at least. Good to hear from you, great to hear you're back working on the metadata registry.
