- summary Phenotype LogicalDefinitions
"Logical Definitions" is the term we use for definitions expressed in a logic language such as OWL. For phenotype ontologies, logical definitions connect phenotypes to classes in multiple OBO library ontologies.
Logical definitions are expressed using the Web Ontology Language (OWL). For historic reasons, some of these logical definitions are authored in OBO-Format, which is a restricted subset of OWL.
