I would like to use URNs in a project of mine. And I am hardly willing to apply my humble project for official IANA registration but would like to keep from violating standards if possible. That's why I'd like to know if there is a standard (or de-facto common practice at least) NID to be placed instead of private in the following example:

urn:private:mycompany:myproject:mycollection:myresource

According to rfc2611 you can define any NID you like so long as it starts with "X-". Such namespaces are considered experimental:

No provision is made for avoiding collision of experimental NIDs; they are intended for use within internal or limited experimental contexts.

As there is no registration, no registration maintenance procedures are needed.

  • FYI, namespace id starting with 'X-' is no longer allowed, per [rfc8141](https://tools.ietf.org/html/rfc8141#section-5.1) – user3076105 Apr 23 '21 at 19:45
