Class-Individual Relationship

based on https://www.taoke.de/ke/Conceptual%20Meta%20Modeling/Class-Individual-Relationships/index.html

The OntoGraph in Figure MetaOntologyRT) shows the relationship between the car designer Marcello Gandini and the car model Lamborghini Miura, which he designed in 1966. The class ^Miura is a subclass and at the same time an instance of the class ^Lamborghini, which itself is a subclass and instance of the class ^Car. TheOP definition for ◊is_Designer_of is
(^natPerson, ◊is_Designer_of, ^Car)

This makes clear that >NPS-Marcello_Gandini is the designer of the car model ^Miura rather than each particular ^Miura.

Classes and particulars can also be connected by relators and thus connect KSs between the SL layer and the PL layers. The relator >>TaxonAuthor_Bear (s. Labeled Property Graph in Figure LPG-TxBear) expresses that Carl Linnaeus created the taxon for ^Bear in 1758 and is an instantiation of the OP ◊TaxonAuthor with

(»TaxonAuthor_Bear, .TaxonYear, 1758) and
(^Bear, »TaxonAuthor_Bear, >NPS-Carl_Linnaeus).

In general relationships between particulars and classes are allowed. Here are some more examples:

(>Yo-Yo_Ma, ◊isExpertOf, ^Violin) or the inverse
(^Violin, ◊hasExpert, >Yo-Yo_Ma)
(>NPS-Albert_Einstein, ◊isCreatorOf, ^Special_Theory_of_Relativity) or
(^Special_Theory_of_Relativity, ◊hasCreator, >NPS-Albert_Einstein)
