Re: informal URN namespace identifiers

[Benja Fallenstein <[e-mail]>]

Hi Peter,

urn-5 was intended for actual use, and there's software by our group
publicly available that generates them internally and there are a few
files on the web containing them. I don't know if anyone's using the
software at the moment, quite possibly not, but I have in the past and
may again -- not that I'd really expect noticeable breakage, but I
think it would be quite a strange thing to do to un-assign an assigned
URN namespace of all things!

That said, if by "clean up" you mean inserting the parts IANA was
supposed to insert, that could make sense (such as, according to the
process as it was when urn-5 was registered, the registration date,
and arguably the "replace xxx" part in the urn-7 registration, though
IIRC when I last looked the process was to use a placeholder and tell
the reader that. The urn-5 registration is actually still an example
of that, which is probably an oversight on my part, since the
registration was updated once and I could have inserted the actual
identifier then.)

All the best,
- Benja
