Import chain of taxonomically arranged Uberon modules. Each combined module at different taxonomic levels imports the relevant native ontologies as well as bridge files that specify the logical definitions. The number of equivalent class (EC) or SubClass (SC) axioms in each bridge file are shown, illustrating the contributions of each ontology to the total infrastructure. The files linked with dotted lines represent the mechanism by which a new chicken anatomy ontology (and similarly, archosaur) would be integrated.
