Pattern for Local Unique Identifiers

Local identifiers in Relation Ontology should match this regular expression:
^\d{7}$

Example Local Unique Identifier

0002533   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Relation Ontology should match this regular expression:
^ro:\d{7}$

Example CURIE

ro:0002533

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 RO_. Therefore, you might see local unique identifiers written out as CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 14 mappings to external registries for ro with 4 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE ro:0002533 is used to demonstrate the provides available for ro. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
