Registry Experimental Factor Ontology

The Experimental Factor Ontology (EFO) provides a systematic description of many experimental variables available in EBI databases. It combines parts of several biological ontologies, such as anatomy, disease and chemical compounds. The scope of EFO is to support the annotation, analysis and visualization of data handled by the EBI Functional Genomics Team.

Pattern for Local Unique Identifiers

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

Example Local Unique Identifier
0005147   Resolve
Pattern for CURIES

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

Example CURIE
efo:0005147

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE efo:0005147 is used to demonstrate the provides available for efo. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
