GENO is an OWL model of genotypes, their more fundamental sequence components, and links to related biological and experimental entities. At present many parts of the model are exploratory and set to undergo refactoring. In addition, many classes and properties have GENO URIs but are place holders for classes that will be imported from an external ontology (e.g. SO, ChEBI, OBI, etc). Furthermore, ongoing work will implement a model of genotype-to-phenotype associations. This will support description of asserted and inferred relationships between a genotypes, phenotypes, and environments, and the evidence/provenance behind these associations. Documentation is under development as well, and for now a slidedeck is available at

RDF Information

When using this resource in RDF, the following URI format should be used:$1


Providers are various services that resolve CURIEs to URLs. The example CURIE GENO:0000632 is used to demonstrate the provides available for this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
