(a) The process of representing the SNOMED CT concept Hematoma, stored in RF2 relational release format in the generic OAF ontology representation. The “generic concept” data type of OAF is extended into a “SNOMED CT concept” data type that stores Hematoma with the status “active” and “non-primitive.” This concept has one attribute relationship, Associated Morphology, with a target of Hematoma (morphologic abnormality). It is stored as an inheritable property. (b) The process of representing the NCIt concept Neoplasm, as given in OWL format, in the generic ontology representation. The “generic concept” data type is extended into an “OWL Class” data type, storing annotations such as the class label (not shown). The restriction on Neoplasm (Disease Has Abnormal Cell some Neoplastic Cell) is stored as an inheritable property.
