OIDs provide a persistent identification of objects based on a hierarchical structure of Registration Authorities (RA), where each parent has an object identifier and allocates object identifiers to child nodes.

Pattern for Local Unique Identifiers

Local identifiers in ISO Object Identifier should match this regular expression:
^[\d.]+$

Example Local Unique Identifiers
2.16.840   Resolve
2   Resolve
2.16   Resolve
2.16.840.1   Resolve
2.16.840.1.113883   Resolve
2.16.840.1.113883.6   Resolve
2.16.840.1.113883.6.88   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from ISO Object Identifier should match this regular expression:
^oid:[\d.]+$

Example CURIEs
oid:2.16.840
oid:2
oid:2.16
oid:2.16.840.1
oid:2.16.840.1.113883
oid:2.16.840.1.113883.6
oid:2.16.840.1.113883.6.88

Providers

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 2.16.840 is used to demonstrate the providers available for ISO Object Identifier. A guide for curating additional providers can be found here.

Extra Providers

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