Pattern for Local Unique Identifiers

Local identifiers in Reference Sequence Collection should match this regular expression:
^(((AC|AP|NC|NG|NM|NP|NR|NT|NW|XM|XP|XR|YP|ZP)_\d+)|(NZ\_[A-Z]{2,4}\d+))(\.\d+)?$

Example Local Unique Identifier
NP_012345   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Reference Sequence Collection should match this regular expression:
^refseq:(((AC|AP|NC|NG|NM|NP|NR|NT|NW|XM|XP|XR|YP|ZP)_\d+)|(NZ\_[A-Z]{2,4}\d+))(\.\d+)?$

Example CURIE
refseq:NP_012345

Metaregistry Reference Sequence Collection

The metaregistry provides mappings between the Bioregistry and other registries. There are 7 mappings to external registries for refseq.

Providers

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