2012 The Units Ontology: a tool for integrating units of measurement in science

Pattern for Local Unique Identifiers

Local identifiers in Units of measurement ontology should match this regular expression:
^\d{7}$

Example Local Unique Identifier

0000080   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Units of measurement ontology should match this regular expression:
^UO:\d{7}$

Example CURIE

UO:0000080

Pattern for RDF URIs

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

Example RDF URI

http://purl.obolibrary.org/obo/UO_0000080

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 , the banana looks like UO:. Therefore, you may see local unique identifiers for this resource that look like UO:0000080 (instead of the canonical form 0000080) and CURIEs for this resource that look like UO:UO:0000080 (instead of the canonical form UO:0000080). 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 13 mappings to external registries for this resource with 3 unique external prefixes.

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 0000080 is used to demonstrate the providers available for Units of measurement ontology. Some providers may use a different example, which is displayed in the table below. 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.
