Applying RFC 2141 is fine from my point of view. As such I need to
update the examples I provided earlier to reflect marlin and phoenix
as subdomains of the avalon domain.

Is that what you want to do? There is no sub-domain notion within RFC 2141.

The format of a URN is "urn:" <NID> ":" <NSS>. NID is Namespace IDentifier,
and NSS is Namspace Specific String. One example might be:

urn:avalon:home.work

where "urn:" is required, avalon is the NID and home.work is the NSS. In
all of your examples, the NID was apache, and everything else was the NSS.

update merlin specific keys to be RFC 2141 based on
a *apache:avalon:merlin* domain

If "domain" is supposed to be NID, that would not be valid. The ':'
character is not valid within an NID, and is valid within the NSS. So your
string would be interpreted as having an NID of apache, with avalon:merlin:
being part of the NSS, which is probably not what you're going to want
internally when you process the NSS. Alternatively, you could use
apache-avalon-merlin as an NID.

Yep - I was looking at the excluded charcter list - not the actual included list.

Valid options for the NID (Namespace Identifier) for something like Merlin would seem to include:

apache-avalon-merlin: (using hyphen because "." and ":" are not allowed)

or

avalon-merlin:

or

merlin:

Given that there isn't a DNS like domain name equivalence here - I'm now thinking it is easiest to run with:

avalon: + the avalon standard specification strings

phoenix: + the phoneix standard specification strings
merlin: + the merlin standard specification strings
fortress: + the fortress standard specification strings
See how easy it is for to change my mind!

;-)

Cheers, Steve.
