DNS based URI without any set access semantics?

2002-07-25 Thread Clark C . Evans
IETF Gurus, I'm looking for a URN scheme that uses DNS for uniqueness (perhaps in conjunction with a date) but doesn't have any attached semantics. I'm asking this beacuse XML has the duck problem. It uses URIs for namespace names, but only the URI syntax (for uniqueness), thus you see

ick. please don't embed URIs in URNs. that will just tempt people to use the embedded URIs and not treat them as URNs. I can see wanting to have a URN that's based on DNS, but there shouldn't be any expectation that you can derive a URI from the URN just by modifying the syntax. that defeats
