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

The metaregistry provides mappings between the Bioregistry and other registries. There are 12 mappings to external registries for this resource with 3 unique external prefixes.

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 0005147 is used to demonstrate the providers available for Experimental Factor Ontology. 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.
