RFC 6920: Naming Things with Hashes
Potentially a useful alternative to tag URIs and uuid URNs for something I’m looking do implement.
I found this by accident when looking for an alternative to this internet draft that attempted to defined a hash urn namespace. Unfortunately, that seemed to go nowhere, but this ni: URI namespace looks promising. I read some objections to it that objected to the use of ; (which is is generally used to introduce fragments at the end of a path), but this isn’t something to be parsed, only validated at most. It’s only if you’re actually trying to resolve a URN (in which case you should be able to recognise the pattern) that you need to detect that kind of thing.
Anyhoo…
