Logo for Cell Ontology The Cell Ontology is designed as a structured controlled vocabulary for cell types. The ontology was constructed for use by the model organism and other bioinformatics databases, incorporating cell types from prokaryotes to mammals, and includes plants and fungi.

Pattern for Local Unique Identifiers

Local identifiers in Cell Ontology should match this regular expression:
^\d{7}$

Example Local Unique Identifier
0000062   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Cell Ontology should match this regular expression:
^CL:\d{7}$

Example CURIE
CL:0000062
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 Cell Ontology, the banana looks like CL:. Therefore, you may see local unique identifiers for this resource that look like CL:0000062 (instead of the canonical form 0000062) and CURIEs for this resource that look like CL:CL:0000062 (instead of the canonical form CL:0000062). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.
