9 Properties

Things can have certain characteristics. To express them, natural and artificial languages make use of syntactic elements like adjectives / adverbs, or attributes / slots, respectively. Examples are: the severity of a rhinitis (a severe or minor); the shape of a nose (bulbous, pointy, flattened); the size of a filing cabinet; the size of a clinical trial (the number of participating patients); the number of centers comprising mono- and multi-center trials; the age of a patient (which may affect the inclusion or the exclusion in a trial); the reputation of a university.

In the following, we present the GFO account on properties, which consists of two parts: First, the distinction between abstract property universals and their concrete instances, which are called property individuals.21Second, both property universals and property and individuals must be distinguished from their respective values.
