Pattern for Local Unique Identifiers

Local identifiers in Chemical Entities of Biological Interest should match this regular expression:
^\d+$

Example Local Unique Identifier

138488   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Chemical Entities of Biological Interest should match this regular expression:
^CHEBI:\d+$

Example CURIE

CHEBI:138488

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 Chemical Entities of Biological Interest, the banana looks like CHEBI:. Therefore, you may see local unique identifiers for this resource that look like CHEBI:138488 (instead of the canonical form 138488) and CURIEs for this resource that look like CHEBI:CHEBI:138488 (instead of the canonical form CHEBI:138488). 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 19 mappings to external registries for this resource with 8 unique external prefixes.

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

http://purl.obolibrary.org/obo/CHEBI_$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 138488 is used to demonstrate the providers available for Chemical Entities of Biological Interest. 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.
