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

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 Units of measurement ontology, 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 10 mappings to external registries for uo with 2 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE uo:0000080 is used to demonstrate the provides available for uo. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
