Pattern for Local Unique Identifiers

Local identifiers in Archival Resource Key should match this regular expression:
^/*[0-9A-Za-z]+(?:/[\w/.=*+@\$-]*)?(?:\?.*)?$

Example Local Unique Identifier

/12345/fk1234   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Archival Resource Key should match this regular expression:
^ark:/*[0-9A-Za-z]+(?:/[\w/.=*+@\$-]*)?(?:\?.*)?$

Example CURIE

ark:/12345/fk1234

MIRIAM Namespace Embedded in LUI

The legacy MIRIAM standard for generating CURIEs with this resource includes the 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.
