Answer by the British Library:
„“I think there may be some confusion about what an ARK is.
The use of ARK identifiers does not require participation in external ARK resolvers. Please see the specification for details https://tools.ietf.org/html/draft-kunze-ark-18 but specifically, the discussion around the Name Mapping Authority Hostport (NMAH, 2.1)
As you can see from the n2t.net site itself, http://n2t.net/e/partners.html, the British Library is not currently a partner in their project, and our ARKs cannot therefore resolve through it.”
A persistent identifier scheme accepting only local resolvers ist for me nothing but a joke.
URL isn’t working!
