Yes, but you can coin names without binding them to anything, or without being clear about what you're naming. >> In addition, it needs to be clear what is being named by the URN. >> Otherwise there's no way to ensure persistence of the binding between >> the URN and the resource. > > Given a UUID, there's no way to know *what* is being named without > additional information. How is that a problem in practice, if all you > need is a unique identifier? URNs aren't merely unique; the binding between the URN and the resource named is expected to be persistent. By declaring something to be a URN, you're making both assertions. UUIDs are unique (by definition), but just because you create a UUID for something doesn't mean you're committing to making the binding between the UUID and that something persistent. It follows that not every UUID should be considered to be suitable for use in a UUID URN. (naming is tricky and extremely subtle) Keith
