I would agree as well, but for another reason: the URN namespace is by definition *universal* and *immutable*. It's not an address, but a persistent *name*, perhaps resolvable to an address, or not. In this hierarchy of naming schemes we have, URN's are the highest and most asbstract of them. They name topics. Below them are URI's, which name resources which have something to do with those topics. Then below those are URL's, which tell where those resources can be found. So, URN's are two levels of abstraction removed from a weblink. They are by design so, and should be kept there. I for instance can refer to myself as urn:oid:1.3.6.1.4.1.12798.1.2049.1 . That's not about my site, not about my online presence, but me as myself, as a person. Having procured an OID prefix via IKI ry, here in Finland, I have numbered myself, and that number is then immutable. I have permanently plaecd myself within on ISO/ITU-sanctioned and IETF-embedded namespace, as a *concept*. Please enumerate yourselves and everything under your control like I did years back. Because however bureaucratic the ISO might be, in their namespace management they did something right. In ASN.1 they even encoded this hierarchical namespace of theirs pretty much right, and concisely. And then, IETF has even come to embed all this into their URN syntax, in textual form. That's nice work, and should be respected. Definitely not to be redone, without very good reason. -- Sampo Syreeni, aka decoy - decoy@iki.fi, http://decoy.iki.fi/front +358-40-3648785, 025E D175 ABE5 027C 9494 EEB0 E090 8BA9 0509 85C2
