The OBO Relation Ontology provides consistent and unambiguous formal definitions of the relational expressions used in biomedical ontologies.
ro
RO
Local identifiers in Relation Ontology should match this
regular expression:
^\d{7}$
Compact URIs (CURIEs) constructed from Relation Ontology should match
this regular expression:
^ro:\d{7}$
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 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.
