    comments:
    - the list of applicable slots is inherited from parent classes
    - This defines the set of slots that are allowed to be used for a given class.
      The final list of slots for a class is the combination of the parent (is a)
      slots, mixins slots, apply to slots minus the slot usage entries.

    description: the refinement of a slot in the context of the containing class definition.
    comments:
    - Many slots may be re-used 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

    comments:
    - attributes are an alternative way of defining new slots.  An attribute adds
      a slot to the global space in the form <class_name>__<slot_name> (lower case,
      double underscores).  Attributes can be specialized via slot_usage.

      We call the slot with the serialization the s-slot, the slots used in the {}s
      are v-slots. If both s-slots and v-slots are populated on an object then the
      value of the s-slot should correspond to the expansion.

      PARSE: implement automated normalizations by parsing denormalized strings into
      complex objects (b) GENERARE: implement automated to_string labeling of complex
      objects

      For example, a Measurement class may have 3 fields: unit, value, and string_value.
      The string_value slot may have a string_serialization of {value}{unit} such
      that if unit=cm and value=2, the value of string_value shouldd be 2cm'
