I really don't want to open up the old debate about whether to use URLs or URNs for XML namespace names, but I am curious about how to go about doing it properly with a URN, should that route take my fancy... I tried "asking the internet", but a search for 'URN + assignment' on google provides precious little information, aside from references to the present, lightly populated "registry" and a flurry of papers and documents dating from 1994-5 (have URNs simply gone out of fashion? :-). The apparent process for requesting the assignment of a "top level" URN domain (or 'NID') appears way too heavyweight for most everyday uses, and delegation to lower level naming authorities seems to be non-existent, though I did find a reference to the reserved status of two letter NIDs for "future use as countrycode-based NIDs for eventual national registrations of URN namespaces". Did this ever happen? Is it ever likely to? Maybe I'm just looking in the wrong places, so any pointers to resources would be appreciated. Given that it appears difficult, if not quite impossible, to obtain a properly registered URN-based namespace, why shouldn't I just roll my own, so long as I'm careful? Who's going to challenge urn:uk:co:gid:..., for instance, and stop me using it?. -- Andy Greener Mob: +44 7836 331933 GID Ltd, Reading, UK Tel: +44 118 956 1248 andy@g... Fax: +44 118 958 9005
