Metadata used to describe classes in EFO

Below is a table summarising the metadata used in EFO:

Metadata Annotation Property
Class label - most common name for the class. RDFS:label
Textual definition of class. definition
A referential mapping of the class to other equivalent classes in external ontologies or resources. Subproperties of definition_citation exist which map to specific resources, e.g. SNOMED_definition_citation contains mappings to SNOMED, etc. definition_citation
Synonyms and other alternatives labels used instead of the class label. alternative_term
Curator responsible for creating and/or editing the class. definition_editor
An example demonstrating how the class may be used. example_of_usage
Explanation describing why a class has been made obsolete, providing audit trail. reason_for_obsolescence
An EFO version number capturing when a class was made obsolete. obsolete_in_version
Given value ‘true’ to flag classes that are structural in nature, such as upper ontology classes. While important for ontology engineering, such classes are hidden from Atlas presentation layer as they have proved confusing to users. organizational_class
