 The Platonist view of properties is that they are transcendent universals. They exist independently, and are outside of space and time, unchanging, and causally inert. Clearly such things cannot be parts of ordinary material objects which are inside space and time, change, and participate in causal chains. But objects still are red, large, heavy, and the like—and this in virtue of standing in some relation to the transcendent universals. That relation is usually called exemplification or instantiation, and it is taken as primitive. But, importantly, it is external—objects are related to things outside of themselves—whereas the relation between object and property on constituent ontologies is internal.
