Yup, URNs were part of the "semantic web" craze, so you could e.g. record facts about a book with isbn: scheme URNs. Nothing much consequential ever came from all that committee busywork, but people got to pontificate and sound smart talking about reification and so on. I still wonder who paid for all of it.
