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:
^\d+$

Example Local Unique Identifier

0376   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Variation Ontology should match this regular expression:
^VariO:\d+$

Example CURIE

VariO:0376

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.

The metaregistry provides mappings between the Bioregistry and other registries. There are 10 mappings to external registries for this resource with 2 unique external prefixes.

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

http://purl.obolibrary.org/obo/VariO_$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.

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