Pattern for Local Unique Identifiers

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

Example Local Unique Identifiers

0002533   Resolve
HOM0000022   Resolve

Pattern for CURIES

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

Example CURIEs

RO:0002533
RO:HOM0000022

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 Relation Ontology, the banana looks like RO_. Therefore, you may see local unique identifiers for this resource that look like RO_0002533 (instead of the canonical form 0002533) and CURIEs for this resource that look like RO:RO_0002533 (instead of the canonical form RO:0002533). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

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

When using this resource in RDF, the following URI format should be used:

http://purl.obolibrary.org/obo/RO_$1

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier 0002533 is used to demonstrate the providers available for Relation Ontology. A guide for curating additional providers can be found here.

Additional providers curated in the Bioregistry are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
