Rdf:type is fine for many such examples.

However, it is not always such a good idea to create special
classes/types for every such fact.
For example: 
	My car is red.
	This food tastes good.

To use rdf:type food these statements requires one to create artificial
classes/types for such notions as RedThings, or GoodTastingThings.

One can do it, but it is not always what you want.
