Testing ARKs with N2T

There are two ways to create test ARKs,

1. Test with your own NAAN

If your organization already has its own NAAN, you can immediately create and use a “quick test ARK”. This is an ARK that starts with ark:/99999/9NNNNN_, where NNNNN represents the NAAN (preceded by ‘9’ and followed by ‘_’). There is no need to register a quick test namespace since it is automatically set aside for each NAAN. As with any prefix, there is an infinite number of possible test ARKs in each NAAN’s quick test namespace. Two versions of an example quick test ARK belonging to the BnF (NAAN 12148) are


Note that N2T.net is configured to forward any quick test ARK it receives (second version above) to the appropriate local resolver (first version).

2. Request a shoulder under a shared NAAN

As mentioned, to implement a shoulder under your own NAAN requires no special request. To implement or change a shoulder under a shared NAAN, however, requires getting into the shared NAAN shoulders registry, which means filling out an online shoulder form. For security purposes requests are processed manually. Example reasons for a change may include

  • notifying N2T of a change in your organization’s contact person or resolver URL,
  • updating your organization’s name assignment policy (sample policy),
  • requesting an additional shoulder, eg, to support a significant new body of ARKs or new organizational division, and
  • transitioning your shoulder to another organization that will carry on your work and future use of your shoulder.

Like NAANs, shoulders under shared NAANs are portable. If your organization transitions into or out of a vendor relationship, there is no impediment to taking your shoulder with you.
