Circularity
Medicine and Sports not included in each other
Symbols referenced using fully qualified names
E.g., Roller-Blading@Sports, Anabolic-Steroids@Medicine
Symbol references cause axioms to be added
E.g., Medicine will contain all axioms from Sports
Neither ontology a symbol source for the other
E.g, Sports is not a symbol source for Medicine
- Symbols from one not recognizable in the other
E.g., “Pass” not interpreted as a sports term in Medicine
