a domain ontology would, for most domains, especially scientific ones, need  to include references to special individuals,
Yes, but what is important is to unambiguously identify individuals from classes. For that purpose the identity criteria introduced in OntoClean is of utmost importance. For example:
like zero,  -> criteria of identity: its symbol

like the chemical elements, -> criteria of identity: its chemical symbol in the Mendeleev table

as individuals, like the earth,  -> criteria of identity: its name


This approach works well for people called 'Smith'.
BS
It was only some examples (of course not complete). For people I do not suggest the name but rather e.g., a Social Security Number (SSN).
