Pattern for Local Unique Identifiers

Local identifiers in Ontology Concept Identifiers should match this regular expression:
^[0-9]{12}$

Example Local Unique Identifier
190000021540   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Ontology Concept Identifiers should match this regular expression:
^ocid:[0-9]{12}$

Example CURIE
ocid:190000021540
MIRIAM Namespace Embedded in LUI
The legacy MIRIAM standard for generating CURIEs with this resource annotates the namespaceEmbeddedInLUI as true. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Ontology Concept Identifiers, the banana looks like ocid:. Therefore, you may see local unique identifiers for this resource that look like ocid:190000021540 (instead of the canonical form 190000021540) and CURIEs for this resource that look like ocid:ocid:190000021540 (instead of the canonical form ocid:190000021540). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.
Metaregistry Ontology Concept Identifiers

The metaregistry provides mappings between the Bioregistry and other registries. There are 1 mappings to external registries for this resource with 1 unique external prefixes.

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE ocid:190000021540 is used to demonstrate the provides available for this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
