#
#          ARK Shoulder Registry
#
# Each record in this registry file specifies a shoulder under a particular
# ARK NAAN namespace, in this case, under the NAAN, 99999, that is reserved
# for test ARKs. See https://n2t.net/e/pub/naan_registry.txt for information
# on NAANs and fill out the "Other information" field in the form at
# 
#      https://n2t.net/e/naan_request
#
# if you wish to reserve an ARK shoulder.
#
# Terminology is based on the metaphor of a key (or name or identifier),
# locksmithing jargon, and the concept of a branded plastic key-cover.

# // Reserved NAANs
#
# The non-organizational NAANs below are reserved and meant for sharing
# across organizations. To use one requires reserving a shoulder under it.
#
#       12345 99152 99166 99999
#
# Any recipient of an ARK with a 99999 NAAN should understand that this
# ARK is meant for temporary test purposes and not for archival reference.
# If it resolves at all, it must not be expected to resolve in the future.
#
# The 12345 NAAN is used for example ARKs in documentation. Such ARKs may
# resolve or not, and they should not be used for archival reference.
#
# The 99152 NAAN is used for ARKs that reference vocabulary terms. These
# may or may not resolve, and they are often used in metadata assertions.
#
# The 99166 NAAN is used for ARKs that reference persons or agents. They
# may or may not resolve.
#
# // Opacity in Shoulders
#
# The recommended practice for shoulders is make the "primordinal":
# they should be semantically opaque, start with a "/", followed by one
# or more "betanumeric" letters (bcdfghjkmnpqrstvwxz), and end implicitly
# with (inclusively) the first digit encountered. There is NO fixed,
# exclusive delimiter character to mark the end of a primordinal shoulder,
# so in the ARK,
#
#     ark:/99999/fk48tr3g
#
# the shoulder is ark:/99999/fk4.
#
# // Quick Test ARK Shoulder Convention
#
# When presented for resolution at N2T.net, any "quick test ARK", which is
# an ARK of the form
#
#     ark:/99999/9<NAAN>_<remainder>
#
# will be redirected to the same base ARK but hosted at the organizational
# URL (resolver) listed in the NAAN registry for the given <NAAN>.
#
# // Forwarding Unknown ARKs to N2T.net
#
# The administrator of a non-N2T ARK resolver may choose to redirect ARKs
# to N2T.net that it does not know about locally.
