The Variation Ontology (VariO) is an ontology for the standardized, systematic description of effects, consequences and mechanisms of variations. It describes the effects of variations at the DNA, RNA and/or protein level.

Pattern for Local Unique Identifiers

Local identifiers in Variation Ontology should match this regular expression:

Example Local Unique Identifier
0376   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Variation Ontology should match this regular expression:

Example CURIE
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 Variation Ontology, the banana looks like VariO:. Therefore, you may see local unique identifiers for this resource that look like VariO:0376 (instead of the canonical form 0376) and CURIEs for this resource that look like VariO:VariO:0376 (instead of the canonical form VariO:0376). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

RDF Information

When using this resource in RDF, the following URI format should be used:$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 0376 is used to demonstrate the providers available for Variation Ontology. A guide for curating additional providers can be found here.
