Produce one or more mapping strings for the given property's value.
This is a virtual method, to be overridden by subclasses of Persona who have linkable properties.
Each of their linkable properties should be handled by their implementation of this function, examining the current value of the property
and calling callback
with one or more mapping strings for the property's value. Each of these mapping strings will be added
to the IndividualAggregator's link map, related to the
Individual instance which contains this Persona.
prop_name |
the name of the linkable property to use, which must be listed in Persona.linkable_properties |
callback |
a callback to execute for each of the mapping strings generated by this property |
