Phenotype and Trait Ontology (PATO)¶
The Phenotype and Trait Ontology (PATO) is a structured vocabulary for describing phenotypic qualities, attributes, and traits in a species-neutral way [1] [2]. It provides a standardized framework for annotating and analyzing phenotypic data by defining qualities such as size, shape, color, morphology, and other characteristics that can be combined with biological entity ontologies to describe phenotypes [2] [4]. PATO is widely used in phenotype annotation and in the logical definition of phenotype terms across species, supporting data integration and comparative analysis in genetics, developmental biology, and related life science domains [1] [3]. By providing a common language for phenotypic qualities, PATO facilitates cross-species interoperability, computational reasoning, and semantic analysis of phenotype data [4] [5].
Example Usage: Annotate a genetic or phenotype study with PATO terms to describe qualities such as red coloration, increased size, abnormal shape, or altered morphology in association with a specific biological entity, enabling cross-study comparison, semantic integration, and computational phenotype analysis [2] [3].

Usage Example¶
Use the following code to import this ontology programmatically:
from ontolearner.ontology import PATO
ontology = PATO()
ontology.load("path/to/PATO-ontology.owl")
# Extract datasets
data = ontology.extract()
# Access specific relations
term_types = data.term_typings
taxonomic_relations = data.type_taxonomies
non_taxonomic_relations = data.type_non_taxonomic_relations
