## Comments
* Many slots may be reused across different classes, but the meaning of the slot may be refined by context. For example, a generic association model may use slots subject/predicate/object with generic semantics and minimal constraints. When this is subclasses, e.g. to disease-phenotype associations then slot usage may specify both local naming (e.g. subject=disease) and local constraints
