The chemical information ontology (cheminf) describes information entities about chemical entities. It provides qualitative and quantitative attributes to richly describe chemicals.

Pattern for Local Unique Identifiers

Local identifiers in Chemical Information Ontology should match this regular expression:

Example Local Unique Identifier
000410   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Chemical Information Ontology should match this regular expression:

Example CURIE
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 Information Ontology, the banana looks like CHEMINF:. Therefore, you may see local unique identifiers for this resource that look like CHEMINF:000410 (instead of the canonical form 000410) and CURIEs for this resource that look like CHEMINF:CHEMINF:000410 (instead of the canonical form CHEMINF:000410). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

RDF Information

When using this resource in RDF, the following URI format should be used:$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 000410 is used to demonstrate the providers available for Chemical Information Ontology. A guide for curating additional providers can be found here.
