Fig. 2From: Linking rare and common disease: mapping clinical disease-phenotypes to ontologies in therapeutic target validationThe cell line design pattern in EFO links an EFO class ‘cell line’ to external ontologies via import mechanism. An EFO cell line derives_from a cell type class from Cell Ontology, which is part_of an organism – a class imported from NCBI Taxon. EFO cell line class is also a bearer_of a disease – a class imported from ORDO or class native to EFO itselfBack to article page
