The full definitions of the concepts | Pneumonia (disorder) |,|Infective pneumonia (disorder)| and |Bacterial
pneumonia (disorder)| are shown below. Each line represents a defining Attribute with a value.
• | is a | = | pneumonitis |
• , | is a | = | lung consolidation |
• , { | associated morphology | = | inflammation |
• , | associated morphology | = | consolidation |
• , | finding site | = | lung structure | }
Figure 4: Definition of |Pneumonia (disorder)|
• | is a | = | infectious disease of lung |
• , | is a | = | pneumonia |
• , | pathological process | = | infectious process |
• , { | associated morphology | = | inflammation |
• , | associated morphology | = | consolidation |
• , | finding site | = | lung structure | }
Figure 5: Definition of |Infective pneumonia (disorder)|
• | is a | = | bacterial lower respiratory infection |
• , | is a | = | infective pneumonia |
• , | causative agent | = | bacteria |
• , | pathological process | = | infectious process |
• , { | associated morphology | = | inflammation |
• , | associated morphology | = | consolidation |
• , | finding site | = | lung structure | }

Figure 7 illustrates some of these Relationships graphically. | is a | Relationships relate a concept to
more general concepts of the same type. In contrast, Attribute Relationships (such as | Finding site | and
| Causative agent |) relate a concept to relevant values in other branches of the subtype hierarchy.
