      (e.g. java classes, python classes) then is a is used. When translating a framework
      without polymorphism (e.g. json-schema, solr document schema) then is a and

      we can avoid subclassing by defining a class gene_my_organism, adding the slot

      slot will be 'injected into' the gene class.

    description: 'Used on a slot that stores the string serialization of the containing

      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.

      Implementations of frameworks may choose to use this property to either (a)
      PARSE: implement automated normalizations by parsing denormalized strings into
      complex objects (b) GENERATE: 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'
