An Archival Resource Key (ARK) is a Uniform Resource Locator (URL) that is a multi-purpose persistent identifier for information objects of any type.
ark
Local identifiers in Archival Resource Key should match this
regular expression:
^/*[0-9A-Za-z]+(?:/[\w/.=*+@\$-]*)?(?:\?.*)?$
Compact URIs (CURIEs) constructed from Archival Resource Key should match
this regular expression:
^ark:/*[0-9A-Za-z]+(?:/[\w/.=*+@\$-]*)?(?:\?.*)?$
namespaceEmbeddedInLUI
as true. The actual
part that gets prefixed before the local unique identifier regex,
otherwise known as the banana, is ark:
.
Therefore, you might see local unique identifiers written out as CURIEs.
The metaregistry provides mappings between the Bioregistry and other registries. There are
3 mappings to external registries for ark
.

Providers are various services that resolve CURIEs to URLs. The example CURIE
ark:/12345/fk1234
is used to demonstrate the provides available for
ark
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
